Family: Melanotaeniidae

Distribution: The Misool Rainbowfish is currently only known from the clear, moderately fast-flowing jungle streams on Misool Island, west of the Vogelkop Peninsula in Indonesia.  They were introduced to the aquarium hobby in 2001.

PH: 6.0 – 8.5

Temperature: 22°C – 28°C (72 – 82F)

Hardness: 9 – 16dH

Description: At a maximum of 6cm in the hobby, and 8cm (3 inches) in the wild, the Misool Rainbowfish is one of the smaller Rainbowfish.  It has a white belly, a yellow body and a thick blue-black mid-lateral stripe.

Diet: A nutritious varied omnivorous diet will keep your Misool Rainbowfish in top form.  Feed regular portions of live food, including insect larvae, worms and shrimps.

Breeding: Get your breeding pairs into condition by feeding them larger quantities of live food.  Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.  Raise the temperature to mimic the bountiful wet season and spawning should occur. The eggs will hatch within ten days and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar.

Comments: While Misool Rainbowfish are relatively uncommon in the aquarium hobby, they are easy to keep.  Suitable and highly adaptable, they make exuberant, zippy little additions to both the species and community aquarium.  They are adapt well to different water chemistry although will not cope well with rapid changes in pH, so it is best to keep it steady.  As with other rainbows, house in a tank rich in floating vegetation, hiding places created by driftwood, provide open swimming areas and change the water regularly to keep the water clear and clean.

Rainbowfish are a great community species in terms of their temperament and apart from other Rainbowfish species they also live happily with most Tetra species (particularly the Neon Tetra and Black Tetra). They are also great tank mates with Discus, CorydorasCatfish  (particularly Corydoras Sterbaiand Corydoras aeneus) Angelfish, Clown loach, the common Guppyand Platy and most Gourami(such as the Blue Gourami and Dwarf Gourami like the Honey Gourami) Also can live happily with most Danio(particularly the Zebra Danioand Pearl Danio)  and also many Killifish make great tank mates. One thing you should take into consideration when housing rainbows with these recommended species is the water quality. Temperature and Hardness are similar but P.H. can be quite different, although it is not ideal, if you keep your water at a P.H. of 7 this should keep your community happy.

Rainbowfish are schooling fish and should be kept in groups consisting of at least six individuals, preferably no less than 10-15. Mix it up with enough females to give them a rest when the males are on the chase, but provide enough males to bring out their vibrant colours when they are in competition for female attention. Whilst this is beneficial to the health and wellbeing of the fish, a large school is rewarding for the aquarist because a school of iridescent Rainbowfish is more dramatic to the eye than a few shy fish peeking out from behind dense vegetation.

Fish Tropical Fish Aquariums Fish experts Aquarium

Family: Melanotaeniidae

Distribution: The Goldie River Rainbowfish has been found in a wide range of habitats, including swamps, creeks, large rivers and deep pools behind fallen trees.  Specifically, Melanotaenia goldiei has been identified in the Goldie River in Southern New Guinea, and in the Laloki and Brown rivers, and their respective tributaries.  They are very abundant throughout Southern New Guinea.   Melanotaenia goldei have a preference for small, clear, slow moving waters littered with leaves and plant debris.

PH: 7.0 – 8.0

Temperature: 24°C – 28°C (75 – 82F)

Hardness: 8 – 16dH.

Description: Melanotaenia goldiei can reach a length of up to 12cm and can live up to 8 years.  They display a radiant coppery glow on the upper half of their body and creamy white on the lower section.  Dark blue and orange stripes adorn the rest of the body, giving it characteristic Rainbowfish beauty.

Diet: A daily supply of small flakes and weekly supplements of live or frozen bloodworms and brine shrimp will keep your Gold-Line Rainbowfish in top health.  Typical of most Rainbowfish, they are not picky eaters.

Breeding: Gold-line Rainbowfish are relatively simple to breed.  Get your breeding pairs into condition by feeding them larger quantities of live food.  Set up a separate breeding tank with slightly alkaline pH and provide plentiful fine leaved plants, like java moss, or spawning mops.

The eggs will hatch after a week, and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar and keep them separate until they are ready to rejoin the community tank.

Comments: Provide a large amount of short stemmed plants and open swimming areas in your Gold-line Rainbowfish aquarium. This species of peaceful Rainbowfish are suitable for confident beginners and intermediate aquarists as long as their specific water requirements are adhered to. Overall a peaceful, sociable fish, they are suitable for either a Rainbowfish aquarium or a community tank.

Family: Melanotaeniidae

Distribution: Melanotaenia splendida inornata hail from the floodplain rivers and clear streams near the Gulf of Carpentaria, and the northernmost parts of Northern Queensland and Northern Territory.  They are abundant in these areas.

PH: At least 6.5 – 8.0

Temperature: 24°C -33°C (75 – 91F)

Hardness: 8 -10 dH

Description: Reaching a length of up to 15cm in the wild and 12cm in captivity, these gorgeous fish have an intricate chequered pattern of black and yellow streaks.  Throw in a veritable mix of radiant silvery grey and pink with red, blue and yellow along the sides of its body, and you have a Rainbowfish deserved of its name.  Along with this beautiful array of colours, the Chequered Rainbowfish has exceptionally long dorsal and anal fins.

Diet: Feed the carnivorous Chequered Rainbowfish up to twice a day on a nutritious balanced diet of live and processed food.  While they prefer meaty foods, they will live happily on an omnivorous diet.

Breeding: Melanotaenia splendida inornata will readily spawn in the aquarium environment, with the females releasing up to 100 eggs per week.  As they are so easy to breed, be prepared with the amount of fish you will end up with!  If you have an excess, the fry could always be used as live food.

Start by setting up a separate breeding tank with lots of fine leaved plants or spawning mops.   Once hatched, remove the fry to a separate tank to avoid predation.  Raise the fry on small live food, such as baby brine shrimp, or crushed flakes.

Comments: The popular Chequered Rainbowfish is a great fish for beginners as they are very hardy.  For best colouration, include a couple of males in a school of females.  Like other Rainbowfish, they are active, vivacious swimmers so will appreciate a long, well-planted tank for open swimming.  Aim for a 55 gallon aquarium.

Fish Tropical Fish Aquariums Fish experts Aquarium

Family: Melanotaeniidae

Distribution: Melanotaenia praecox was initially found in the tributaries of the Mamberamo and Wapoga River systems in West Papua.  They have since been found in the small creeks and swampy waterways near Siewa in the Tirawiwa River system, a remote area of northern West Papua.

PH: 6.5 – 8.0

Temperature: 24°C -28°C (72 – 79F)

Hardness: 5 – 30dH

Description: This miniature Rainbowfish exhibits the usual Rainbowfish characteristics of big eyes and twin dorsal fins.  Additionally they have brightly coloured fins, yellow on females, red on males, and pinkish grey scales with neon blue tonings that range from brilliant lavender through to teal.  Females are smaller and more silvery than males. They grow up to 6cm (2 inches).

Diet: Dwarf Rainbowfish are omnivores and will readily accept most commercial foods, whether live or frozen.  Feed them high quality flake or pellet food and offer large amounts of live food like brine shrimp, blood worms and tubifex worms.  They love chopped up, defrosted peas and will even eat garden lettuce as a plant food source.  An easy feeder!

Breeding: Breeding Dwarf Rainbowfish is relatively easy.  Get your breeding pairs into condition by feeding them higher quality and quantities of live and plant based food.  Set up a separate breeding tank with lots of fine leaved plants or spawning mops and keep the water soft and acidic. Keep the breeding pair in a species only tank as they will cross breed with other Rainbowfish.  Watch the female to make sure she doesn’t get stressed with the mating chase ritual.

While the breeding process is initially simple, the fry can be challenging to raise because of their size.  The eggs will hatch within a week and should be removed to a separate tank to avoid predation.  Feed on microworms or baby brine shrimp and keep them separate until they are old enough (about two months) to rejoin the community tank.

Comments: Dwarf Rainbowfish are extremely popular in the aquarium hobby because adapt exceptionally well to a beginner’s community aquarium.  They bring their trademark peaceful, colourful personalities to the fray.  Provide aquatic vegetation, submerged logs and other hiding places to keep your fish happy.

While Dwarf Rainbowfish are easy to keep, getting the most out of their spectacular colouration takes a bit of effort.  Use a dark substrate and contrasting colour on the backing of the tank.  Add floating plants and at least a third of the tank should be open water to encourage the fish to swim there.  Allow for an extra few hours of sunlight to further display their radiance.

For basic care, replace at least 25-50% of their water weekly and make sure your tank is at least 20 inches long and 20 gallons in size.  Secure a firmly fitting top as these fish love to jump.

Mountain Rainbowfish

Melanotaenia monticola

Family: Melanotaeniidae

Distribution: Unlike other Rainbowfish, the Mountain Rainbowfish habitat includes high altitude tributuitars with fast-flowing waterways practically void of aquatic vegetation.  Specifically it lives in the upper Purari and Kikori river systems in Papua New Guinea’s Southern Highlands.

PH: 7.5– 8.0

Temperature: 17°C – 25°C (63 – 77F)

Hardness: 16dH

Description: With blue-grey to green variances on the back and a coppery-golden sheen to their scale margins, Mountain Rainbowfish are very beautiful.  The male fish is further adorned with a pale lilac breast and fin colouration.  They grow up to 10cm (4 inches).

Diet: The omnivorous Mountain Rainbowfish needs a varied vegetable and protein based diet to stay healthy.  For example, mix high quality flakes with live food such as larvae, worms or brine shrimp.

Breeding: The lovely Mountain Rainbowfish will spawn readily in aquariums, particularly if you keep the temperature over 20C (68F).  However, they will spawn in lower temperatures.

Get your breeding pairs into condition by feeding them larger quantities of meaty food. You will know when your male Mountain Rainbowfish is ready to spawn because overall colouration and coppery scale edges will darken and become more intense and an orange colour will appear on the top of his head. Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.

The eggs will hatch within 12 days and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar.

Comments: Keep the oxygen levels high and keeping Melanotaenia monticola should be relatively straight forward.  Good filtration is imperative, as is hiding places, and fresh water changes.  Rock, plant and driftwood cover is perfect in this case.  Create your aquarium environment with their natural habitat in mind.  Mountain Rainbowfish are suited to both species and community tanks.

Barred rainbowfish

Chilatherina fasciata

Family: Melanotaeniidae

Distribution: The Barred Rainbowfish lives in northern New Guinea, including the river systems of Markham, Ramu, Sepik and Mamberamo in both the lowlands and highlands. The preferred habitat of the Barred Rainbowfish is a clear rainforest stream consisting of gravel or sand and littered with leaves and rainforest debris. They have also been found in Lake Wanam in Papua New Guinea. With an appreciation for sunlight and warm waters, Chilatherian fasciata is one of the most abundant fishes in Northern New Guinea.

PH: 7.1 to 8.1

Temperature: 28° -32°C (82 – 90F)

Hardness: 0-12DH

Description: The Barred Rainbowfish can be roughly 14 cm (5.5 inches) long. With the overall specific coloration depending on its geographical origins, it usually ranges from brownish to bluish green on the back with yellow/white sides. Most adult males have black bars on their lower sides and will enhance and intensify their colours to a deep bronze/red-orange during breeding. The females range from silver to olive with clear fins. Both share a uniquely deep, laterally compressed body. Overall, Chilatherian fasciata are a beauty to behold in the world of rainbowfish.

Diet: Mimic the natural diet of the Chilatherian fasciata by serving up a veritable delight of fish algae, live insect larvae (and other live foods), and processed foods. Allow for natural algae growth as it is on the top of the menu for tastiness in this rainbowfish’s mind.

Breeding: Male aggression is the biggest issue when breeding this species. It can be quite dangerous for the females if you don’t provide two or three females for each male. Set up a separate breeding tank filled with dense vegetation like java moss.

Keep the water temperature in the upper eshalons of the recommended range to decrease incubation time.

It is advisable to move the spawning medium into a different container to avoid predation. Feed fry with newly hatched brine shrimp or powdered flake food.

Comments: The Barred Rainbowfish is a common choice for all aquarists as they are relatively easy to care for. Opt for a well-planted tank with the intention of mimicking its natural habitat. A plentitude of hiding spots, open swimming areas and submerged diftwood will make for a satisfied rainbowfish. Just like their rainbowfish relatives, their serene, shoaling fish nature makes them a great addition to any community tank.

Tip: These fish are sun worshippers…give them a couple of sunlight exposure each day and watch them shine!

Melanotaenia Australis

Western rainbowfish/Australian rainbowfish

Melanotaenia australis

Family: Melanotaeniidae

Distribution: Found in the Kimberly and Pilbara regions of Western Australia and both the eastern and western parts of Darwin in the Northern Territory, Australian rainbowfish live in lakes, pools in drying waterways, lagoons, marshlands, creeks and rivers. Melanotaenia australis is considered to be one of the most abundant species of Rainbowfish in Australia.

PH: 6.0 – 8.0

Temperature: 23°C – 32°C (73 – 90F)

Hardness: 3 – 30DH.

Melanotaenia australis are used to significant changes in water hardness. Ideally keep your Australian rainbowfish in hard water from April through to October then gradually make the water softer to mimic the coming of the ‘wet season’ in their natural habitat. Ensure that all changes to water conditions are gradual.

Description: The Australian Rainbowfish can reach a length of 10 cm (4 inches). This hardy schooling fish is noted for its pair of zigzagging blackish lines that can be seen on the lower sides of the body. Its main body colour varies depending where it comes from and can range from brown, olive, black and white, with either indistinct or distinct double or single orange-red stripes.

The males are usually longer, more vibrantly coloured, have bigger dorsal fins and are deeper bodied than the females.

Diet: In the wild, Melanotaenia australis thrive on an omnivorous diet with a preference for insects, worms, aquatic larvae and crustaceans. They are not fussy eaters and will take most aquarium foods. For optimum health, choose a combination of live and frozen food for their aquarium diet.

Breeding: Australian Rainbowfish reach sexual maturity when they are around 4 cm (1 ½ inches) and are moderately easy to breed. Set up a separate breeding tank of approximately 30 litres (8 gallons), and provide an abundance of java moss or similar in your set up. Be

prepared for vigorous and aggressive chasing. Provide a couple of females for each male to reduce the stress of the chase. Eggs will be deposited daily and the vegetation will be used as the spawning medium. As long as your fish are well fed and the vegetation plentiful, you may not need to remove the parents. Even with these safeguards, the parents could still eat their young.

Tip: The Australian rainbowfish are often overlooked by people searching for a colourful addition to their aquarium community. Seemingly the perfect fish – adaptable, peaceful, full of energy – people will still walk past them because as juveniles their colour lacks the vibrancy that it will exhibit in adulthood.

Comments: Australian rainbowfish are a popular choice for both beginners and the more advanced fish enthusiasts. Its highly adaptable, hardy, social nature makes it an easy and rewarding fish to keep.

Opt for gentle water movement, driftwood and live plants when setting up your aquarium.

This popular Australian prefers an active social life rather than that of solitude ensuring that they will thrive in a school of fellow rainbowfish. They are active swimmers so be sure to provide open swimming areas.

Perform frequent partial water changes to ensure optimum health of your fish.

Fish Tropical Fish Aquariums Fish experts Aquarium

Family: Melanotaeniidae

Distribution: Melanotaenia affinis are found across Northern New Guinea from Oomsis River to West Papua.  Commonly found in the Markham, Ramu and Sepik rivers, their preferred habitat includes clear rainforest streams, swamps, pools and lagoons abundant in vegetation and submerged logs.

PH: 6.0 – 7.0

Temperature: 21°C -27°C (70 – 80F)

Hardness: 3 – 16dH

Description: The attractive New Guinea Rainbowfish has different colouration depending on location and water conditions.  Olive, brown, blue, silver, white or red body colours, orange or dark stripes and yellow to translucent fins are some of the varied colourations you might see.  Even the shape of the fish is determined by location and water chemistry.  New Guinea Rainbowfish grow up to 13cm (5 inches).

Diet: A nutritious varied omnivorous diet will keep your New Guinea Rainbowfish in good form.  Use dried food as a base and supplement with live or frozen food.  They are not picky eaters and will even nibble at lettuce or spinach.

Breeding: Breeding the New Guinea Rainbowfish can be successful and quite simple if you follow their usual water requirements, and mimic the natural habitat during the abundant wet season.

Get your breeding pairs into condition by feeding them larger quantities of live food.  Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.

The eggs should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar and keep them separate until they are ready to rejoin the community tank.

Comments: The hardy New Guinea Rainbowfish is generally easy to keep because they are used to variances in water quality and conditions.  Use their natural environment as a template for your aquarium – include hiding spots, gentle water movement and plentiful aquatic vegetation.    Change at least 25% of the water on a weekly basis.  A tank sized at  48″ x 12″ x 12″ (120cm x 30cm x 30cm) and around 110 litres is suited for the energetic New Guinea Rainbowfish, making sure that there are large areas provided for open swimming.

Family: Melanotaeniidae

Distribution: Known only from Batanta Island in the Raja Ampat Islands of West Papua, Melanotaenia batanta were collected from Warmon Creek on the northern tip of the island. Batanta rainbowfish were only found in a 400 metre section of clear, moderately fast-flowing brackish mangrove habitat.

PH: 7 to 9, although naturally it varies considerably according to the seasons.

Temperature: 18° -32°C (72 – 90F)

Hardness: 0-12DH, although naturally it varies considerably according to the seasons.

Description: With an overall blue body, white to silver lower body, orange stripes between each horizontal scale, a dark blotch behind the eye and translucent fins, the Melanotaenia batanta makes for yet another beautiful rainbowfish variety. Males and females are alike in colouration making them unique in terms of typical rainbowfish gender colour and shape differences.. Males may reach a maximum size of 10 cm, but females are usually less than 8 cm.

Diet: Whilst there is no known record of this freshwater beauty being kept in aquarium conditions, we can infer that by mimicking the natural diet of the Melanotaenia batanta and providing a mixed omnivorous diet of live, frozen and processed aquarium foods, the aquarist would have the best chance of seeing a thriving fish community.

Breeding: There is no known record of this species being bred in captivity. Should you be lucky enough to be in a position to do so, it would be best to follow a breeding set up similar to its Melanotaenia relatives.

Comments: As yet, there is no recording of live specimens having been collected for the aquarium hobby. As with breeding, by replicating the habitat of Batanta Island, the hobbyist would be better set up for a healthy school of Batanta Rainbowfish . Choose a tank with an array of sheltered areas, secluded hiding spots, dense vegetation and submerged driftwood.

Tip: This species is often confused with its relative the Batanta Island Rainbowfish. Batanta Rainbowfish is a different species.

Family: Melanotaeniidae

Distribution: The Ornate Rainbowfish typically lives in stagnant streams, tannin-stained streams, calm backwaters or creeks with either no flow, or very little. The Ornate Rainbowfish will group around tree debris and banks dense in vegetation.  Geographically, they can be found on the islands and coastal drainages off the coast of Southern Queensland and northern New South Wales in Australia, specifically east of the Great Dividing Range and as far north as Waterpark Creek.  Rhadinocentrus ornatus is yet another victim of habitat loss due to land clearing, housing and commercial developments.

PH: 4.0 – 7.0

Temperature: 20°C -32°C (68 – 90F) Although these fish have known to be able to survive in 8°C (47F) waters.

Hardness: 0 – 6 dH

Description: The Ornate Rainbowfish couldn’t be more deserving of its name.  With stunning and elaborate decorations of dark scale margins, neon blue scales, shimmering shades of blue, red or pink, and tints of yellow, black, red and purple throughout dependent on the individual specimens, this beautiful little Australian is truly eye-catching.   They are a small Rainbowfish and will only grow up to 6cm in length.

Diet: As with all Rainbowfish, the Ornate Rainbowfish are omnivores, easy feeders and will readily accept most commercial foods, whether live or frozen. A prepared food base mixed in with a supplement live diet of insects, small crustaceans, algae, daphnia and spirulina flakes will do the trick.  Allow for natural algal growth to further supplement their vegetable intake.

Breeding: Ornate Rainbowfish will readily spawn in aquariums providing you provide specific water conditions; acidic, soft water.  Get your breeding pairs into condition by feeding them higher quality and quantities of live and plant based food.  Set up a separate breeding tank with suitable spawning medium, that is, lots of fine leaved plants or spawning mops.

While the breeding process is initially simple, the fry can be challenging to raise because of their size.  The eggs will hatch within a week and should be removed to a separate tank to avoid predation.  If this is not possible, keep the small fry in a well decorated tank with lots of hiding places and a small amount should survive.  Feed on microworms or powdered flake food and keep them separate until they are old enough to rejoin the community tank.

Comments: Ornate Rainbowfish are popular in the aquarium hobby because of their exceptional beauty.  While they are relatively easy to keep, they are not recommended for beginners simply because of their size, temperament and inability to thrive as well as other rainbows in a community tank.  They are very stress-sensitive and delicate.

These little rainbows will do well in a species tank, about 30 litre (8 gallons) – about six Ornate Rainbows will suit this sized tank.

Provide large amounts aquatic vegetation, sheltered areas and other hiding places to keep your fish happy.

Article/Books:

Recommended Compatible Species:They will live happily with Tetra species (particularly the Neon Tetra and Black Tetra).

Arfak’s Rainbowfish

Melanotaenia arfakensis

Family: Melanotaeniidae

Distribution: Melanotaenia arfakensis live primarily in the streams, but also in the lagoons and swamps, on the Prafi Plains of Western New Guinea. The Arfak Rainbowfish preferred habitat includes tributaries rich in soil and sediment deposits, submerged logs, branches, and sub-surface vegetation.

Now listed as “Vulnerable” in the IUCN Red List of Threatened Species, Melanotaenia arfakensis is under dire threat due to an increased level of unsustainable land clearing and introduced species in the nearby Arfak mountains.

PH: 6.5 – 7.5

Temperature: 24°C – 28°C (75 – 82F)

Hardness: Approximately 0-6gDH – based on the Prafi River tributaries.

Description: The male Arfak Rainbowfish can be roughly 10 cm (4 inches) long while females are usually less than 8cm. The body is a gorgeous light mauve with silvery reflections, a bluish mid-lateral band and yellow-orange stripes between each horizontal scale row. The males are usually more vibrantly coloured and deeper bodied than the females.

As these fish are not common aquarium species, the details of this rainbowfish’s social habits, general temperament and gender traits are sketchy. Despite this, we can draw educated behavioural estimations from other rainbowfish varieties, such as Boeseman’s rainbowfish (Melanotaenia boesemani) or Duboulay’s Rainbowfish (Melanotaenia duboulayi) that are more commonly exhibited in aquariums. This leads us to infer a fish that is social, peaceful, and hardy in nature and who revels in abundant aquatic plant life in which to play hide and seek.

Diet: It is advisable to provide your Afrak Rainbowfish with a varied diet of dry and live food. An ideal mixture of brine shrimp, insect larvae and high-quality flake food would make for a happy fish.

Breeding: Melanotaenia arfakensis have never been bred in an aquarium. In their natural environment, this species distinctly pair, are open stream egg scatterers and do not guard their eggs. It is not known how they would react in a captive environment.

In general, rainbowfish should be bred in a separate spawning tank. You should lower the pH slightly and provide your fish with abundant vegetation. Rainbowfish are known to go wild during spawning so to avoid excessive stress, breed two or more females with

three or more males at any given time. This reduces the incidence of aggressive chasing. Additionally, it is advisable to remove the parents in order to prevent the young from being eaten.

Tip: Try to mimic its natural environment as closely as possible in the aquarium.

Comments: The Arfak Rainbowfish is not a common aquarium species and little is known about its specific requirements. All information here is based on its natural habitat or general information from other closely related rainbowfish species.

In general, Rainbowfish are highly adaptable, interesting and active little fish well suited to aquarium life. Their passive, community-loving nature makes them ideal for a medium to large tank.

Family: Melanotaeniidae

Distribution: The sensitive Celebes Rainbowfish is endemic to Sulawesi (Celebes), an Indonesian island located west of Borneo and east of Papua New Guinea.  It is specifically found in the fresh slow-moving waters in the foothills of this area.  Additionally, Marosatherian ladigesi has also be found in the Philippines.  They are listed as vulnerable on the IUCN Red List of Threatened Species.

PH: At least 7.0 – 8.0

Temperature: 25°C -30°C (77 – 86F)

Hardness: 10-20dH

Description: With large eyes, a neon green-blue stripe that runs along the backbone of the fish, and distinctive two-toned fins that vary from black to lemon, the slender Celebes Rainbowfish will add an individual brilliance to any hard water aquarium.  The males usually have longer fins and slightly brighter colours than the females but other than that, the two sexes are very similar.  Immature Celebes Rainbowfish take a while to grow into their beautiful colours, often displaying colourless fins and noticeably duller body colouration.  They grow up to 7.5cm (3 inches) and live for up to 5 years.

Diet: Feed the omnivorous Celebes Rainbowfish up to twice a day on a nutritious balanced diet of live and processed food.  As their throats are small, cater accordingly by feeding smaller types of food.  Such foods as blood worms, brine shrimp, insect larvae and tubifex will keep your brightly coloured Celebes happy and healthy.

Breeding: It is believed that breeding the Celebes Rainbowfish is moderately difficult, and quite uncommon, although certainly possible. Start by setting up a separate breeding tank with lots of fine leaved plants such as Cambomba, Java Moss, Mifoil or Riccia.  For best results, cool the water to 21-23°C (70-73F) and the breeding pair should begin to spawn among plant leaves.  Once hatched, remove the fry to a separate tank to avoid predation.  Raise the slow-growing fry on small live food, such as baby brine shrimp, or crushed flakes.  Please note that it could take up to five months before it is safe to allow the fry to rejoin the community aquarium.

Comments: Simulate the natural environment of the Celebes Rainbowfish as much as possible. However, there are a few extra things you can do to provide the most spectacular environment for this little wonder.  These include positioning the tank to allow for extra sunlight, adding an extra half a teaspoon of salt per gallon of water and providing dense aquatic plant cover (Water Wisteria, Hornwort, Java Moss).

Go for a tightly fitted top for your tank as these fish are vivacious swimmers and jumpers. Change 25-50% of the water each week as Celebes Rainbowfish are sensitive to water quality.

If you know that your specimen comes directly from the wild, you will need to be extra careful, as wild-caught Celebes Rainbowfish are very delicate.

Tip: Most aquarium stock come from the wild, so keep its vulnerability listing in mind when you purchase one.  Intricate fins mean that they are extra susceptible to diseases like fin rot.

Family: Melanotaeniidae

Distribution: Typically found in swamps and small, clear creeks, MacCulloch’s Rainbowfish live in a vast region that encompasses northern Australia to south-western Papua New Guinea.  It can be found from Fly River to Bensbach River in Papua New Guinea, and the Queensland coastal plains, in the McIvor River and in the rainforest creeks of the Daintree River in Australia.

PH: 5.5 -7.5

Temperature: 24°C -30°C (75 – 86F)

Hardness: 12 – 16dH

Description: Papua New Guinean MacCulloch’s Rainbowfish are far more colourful than that of the Queensland relatives.  The former displays a bright yellow tint on its body and has black striped fins.  Both types have silvery-white bodies adorned with red-brown stripes.  The Queensland variety has gorgeous red fins to make up for the rather plain body colouration.  MacCulloch’s Rainbowfish can reach a length of 7 cm (nearly 3 inches).

Diet: Give a combination of small meat and vegetable based foods for optimal health.  Live foods can supplement a base of dried or pellet vegetable food.  MacCulloch’s Rainbowfish are typically easy to feed.

Breeding: Breeding is easy.  Change about 40% of the water and plant an extra smattering of java moss or similar.  The breeding pair will lay and fertilize their eggs each morning.  Remove the fry to a separate tank to avoid predation.  Raise your young fry on finely crushed dry food.

Comments: Easy to keep due to their blasé attitude to water quality, MacCulloch’s Rainbowfish display the usual Rainbowfish characteristics of peacefulness and liveliness.  Keep in an 80cm aquarium that provides hiding places, plenty of aquatic vegetation and large areas in which to swim freely.  It is well liked by both beginners and expert aquarists because of their ability to adapt to different types of water chemistry.

Family: Pseudomugilidae

Distribution: The Forktail Rainbowfish is found in the heavily vegetated, fast flowing jungle streams of Papua New Guinea and Indo-Pacific regions.

PH: 7.0 – 8.0

Temperature: 24°C – 28°C (75 – 82F)

Hardness: 15 – 30dH.

Description: A truly vibrant Rainbowfish, the Forktail or Blue Eye is a sight to behold.  With black and bright yellow tipped fins and tail, silvery-grey bodies and glowing red markings, the Pseudomugil furcatus grows to a meagre 6.5cm (2.6 inches), and lives up to 3 years.  The males usually have a longer dorsal fin and are more brightly coloured than females.

Diet: Forktail Rainbowfish can be fed on a staple diet of dried food and supplemented with small live or frozen food.

Breeding: Pseudomugil furcatus is easy to breed.  The Forktail Rainbowfish only lays a few large eggs at a time, only 5-10 eggs a day and they will be laid on busy plants such as java moss.

The eggs will hatch within 14 days and should be removed to a shallow container to avoid predation.  Feed the tiny fry on baby brine shrimp or dust food and keep them separate until they are ready to rejoin the community tank.

Comments: Mimic the colourful Forktail Rainbowfish’s natural environment by providing dense aquatic vegetation and regular fresh water changes.  The males grow very rapidly and can often appear aggressive to females, so provide hiding places throughout the tank.  A sandy substrate and low lighting will help bring out their beautiful colours.  Overall a peaceful, sociable fish, they are suitable for either a Rainbowfish aquarium or a community tank.

Family: Melanotaeniidae

Distribution: Lakamora Rainbowfish are found in Lake Lakamora and Lake Aiwaso of the Triton Lakes in Western New Guinea.

PH: 7.0 – 8.0

Temperature: 24°C – 27°C (75 – 81F)

Hardness: 6 – 14dH

Description: Melanotaenia lakamora grow up to 5.5cm and exhibit a beautiful silver reflective body with dark mid-lateral stripes and orange-yellow fins and tail.  The males are more deeper bodied than the females.

Diet: Lakamora Rainbowfish will thrive on a mixed nutritious omnivorous diet with a base of flake or pellet food and weekly live or frozen food treats.

Breeding: While Lakamora Rainbowfish are not common in the aquarium hobby anymore, it has been said by expert aquarists that they can be quite simple to breed. It is suggested that you feed your breeding pairs larger quantities of live food than usual to get them into breeding condition. Set up a separate breeding tank with abundant fine leaved plants, like java moss, or provide artificial spawning mops.

The eggs will hatch within two days and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar.

Comments: These fish are currently uncommon in the aquarium hobby despite the fact that they are easy to keep and suitable for any enthusiastic, knowledgeable aquarist.  This has not always been the case and they are certainly available for purchase within aquarist circles.

Lakamora Rainbowfish do best in community and species aquariums that provide large open swimming areas.  Cater for their occasionally timid nature by providing hiding spots created by drift wood and dense aquatic vegetation.  Make sure your tank has a tight-fitting lid as they have been known to jump.

Family: Melanotaeniidae

Distribution: Endemic to Lake Terbera in the Southern Highlands of Papua New Guinea, the Lake Terbera Rainbowfish prefer clear, mountainous streams that are abundant in aquatic vegetation.

PH: 7.0 -8.0

Temperature: 20°C -26°C (68 – 79F)

Hardness: 12 – 16dH

Description: With a bright yellow body and blue-black mid lateral stripes, the Lake Terbera Rainbowfish will be sparkle to any Rainbowfish aquarium.  Fins are usually yellow or red.  The Lake Terbera Rainbowfish grow up to 12cm (4.7cm).

Diet: The Lake Terbera Rainbowfish is a lover of all things meaty.  Feed your fish on lives ants, insect larvae, brine shrimp and beetles, filamentous green algae and fruit and you have one happy fish!

Breeding: These fish are prolific breeders in the wild so they should be easy to breed in a suitable aquarium set up.  Start the process by getting your breeding pairs into condition by feeding them large amounts of meaty live foods. Set up a separate breeding tank with lots of fine leaved plants, like java moss, or provide artificial spawning mops.

After hatching, the fry should be removed to a separate tank to avoid predation.  Feed on crushed algal flake or baby brine shrimp, and keep them separate until they are ready to rejoin the community tank.

Comments: Keeping Lake Terbera Rainbowfish in a community or species aquarium is quite easy.

Remember that they like clear, clean water so regular water changes are a must.   With their trademark non-aggressive natures, they will do well in a community aquarium.  Keep your tank well-planted, and provide plenty of areas for open swimming.    As they a larger fish, use a 240 litre, 4ft tank to ensure plenty of room for all of the tankmates.  These fish are sensitive to nitrate levels and will jump, so fit a tightly secured lid to your tank.

Balloch’s rainbowfish or Glass Blue-Eye

Kiunga ballochi

Family: Pseudomugilidae

Distribution: Gerald Allen and John Paska first found Kiunga ballochi in 1982. Balloch’s Rainbowfish, or the Glass Blue-Eye as it is sometimes known, was collected from the small, shallow, clear tributary streams of the Ok Smak River, about 40 kilometres north of Kiunga, Papua New Guinea. At this stage, the full extent of their distribution range is unknown as most of their natural environment remains unexplored.

PH: Approx 7-8 based on its natural habitat

Temperature: 24° -25°C based on its natural habitat

Hardness: Up 15gDH.

Description: Kiunga ballochi have a mainly transparent body with a silver stomach, bold black borders on its anal fins and dominant translucent yellow bands. They have a moderately deep body for a blue-eye. One of the smaller Rainbowfish species, they grow to a tiny 3cm (1.2 inches). Unfortunately they are listed as critically endangered on the IUCN Red List of Threatened Species.

Not much is known about the social habits, gender traits and temperament of this reclusive freshwater tropical fish although we can infer similarities from a close relative that has been found in the same region, Kiunga Bleheri or Bleher’s Blue Eye, and the understandings of the Melanotaeniidae family.

Diet: Like all of the Rainbowfish species, Balloch’s Rainbowfish need a mixed omnivorous diet to provide optimal health. In an aquarium, this would include live and frozen and vegetable based aquarium food in order to best mimic its diet in the wild.

Breeding: Currently there is no record of this species being bred in an aquarium. In their natural environment, this species distinctly pair, are open stream egg scatterers and do not guard their eggs.

Comments: Balloch’s Rainbowfish do not cope well with being caught and transported. As a result, it is not a common aquarium fish. If you could mimic the small tributaries of the Ok Smak River as much as possible by maintaining water quality according to the prescribed requirements, and provide a large amount of plant life, this species could be a potential for the advanced aquarist.

Family: Melanotaeniidae

Distribution: Melanotaenia ogilbyi is known only from seven specimens collected from the Lorentz River in Western New Guinea in 1907.  Typically the Ogilby’s Rainbowfish lives in streams and swampy environments.

PH: Unknown

Temperature: Unknown

Hardness: Unknown

Description: The live colouration of Ogilby’s Rainbowfish is relatively unknown.  It is believed to be similar to Melanotaenia papuae and Melanotaenia splendida rubrostriata, with intense dark mid-stripes, occasionally red tinges, and a bluish to white body.  Ogilby’s Rainbowfish can grow up to 10cm, but is usually less than 8cm.

Diet: There is not enough data about the diet of Ogilby’s Rainbowfish.  As with other Rainbowfish, it could be theorized that they would do well on a nutritious varied omnivorous diet.

One thing you should take into consideration when housing rainbows with these recommended species is the water quality. Temperature and Hardness are similar but P.H. can be quite different, although it is not ideal, if you keep your water at a P.H. of 7 this should keep your community happy.

Rainbowfish are schooling fish and should be kept in groups consisting of at least six individuals, preferably no less than 10-15. Mix it up with enough females to give them a rest when the males are on the chase, but provide enough males to bring out their vibrant colours when they are in competition for female attention. Whilst this is beneficial to the health and wellbeing of the fish, a large school is rewarding for the aquarist because a school of iridescent Rainbowfish is more dramatic to the eye than a few shy fish peeking out from behind dense vegetation.

Family: Melanotaeniidae

Distribution: Most of the collections of the Papuan Rainbowfish have been found in rainforest and freshwater streams within a 30km radius of Port Moresby, Papua New Guinea. As yet, the full geographic distribution of Melanotaenia papuae is undetermined.

PH: 7.5 -8.0

Temperature: 22°C – 30°C (72 – 86F)

Hardness: 12-16gH

Description: Melanotaenia papuae exhibit a body colouration of olive-green grading out to either red/purple or yellow/orange, depending on sex, above the mid-lateral line and silvery white below with a red spot and black line features. Females are smaller, at 6cm, and less vibrantly coloured than the males, who grow up to 8cm.

Diet: A nutritious varied omnivorous diet will keep your Papuan Rainbowfish in top form. Feed regular portions of live food, including insect larvae, worms, insects, bloodworms and shrimps. They will also eat dry food.

Breeding: The information available about breeding Papuan Rainbowfish in the aquarium hobby is quite sketchy and rather limited.

It is known that breeding these little beauties can be labour intensive and difficult – definitely not recommended for the aquarist newcomer.

To start the breeding process, set up a separate breeding tank with lots of fine leaved plants, like java moss, or provide artificial spawning mops. About 20-30 eggs will be laid and after a week, they should hatch.

After hatching, the fry should be removed to a separate tank to avoid predation. Feed on crushed algal flake or baby brine shrimp, and keep them separate until they are ready to rejoin the community tank. They will be very small so keep them separate for at least a couple of months until they grow larger.

Comments: Papuan Rainbowfish were once very popular in the aquarium hobby but now are rarely seen. If you do manage to get your hands on one, it is in your best interest, and your fish, to mimic its natural habitat.

Keep your Papuan Rainbowfish in a tank no smaller than 80cm (30 inches) in length, and ensure it is well-planted with floating vegetation, has slow currents and shadowy lighting. Pay careful attention to nitrate levels as these fish can be sensitive to rapid changes in water chemistry.

They should do well in a species or community aquarium providing you adhere to their water chemistry conditions. Make sure you have a tank large enough for open swimming areas and change the water regularly.

Melanotaenia goldei or other such peaceful, similar sized rainbowfish, such as Melanotaenia sexlineata, would serve well as companionable tankmates. The former rainbow is found in the same water systems as Papuan Rainbowfish and will complement each other in a tank. Try danios, They should live happily with most Tetra species (particularly the Neon Tetra and Black Tetra). They also should be good tank mates with Discus, Apistogramma‘s like Apistogramma Cacatouides and Apistogramma Borelli, Corydoras Catfish  (particularly Corydoras Sterbai and Corydoras aeneus) Angelfish, Clown loach, the common Guppy and Platy and most Gourami (such as the Blue Gourami and Dwarf Gourami like the Honey Gourami) Also should live happily with most Danio (particularly the Zebra Danio and Pearl Danio)  and also many Killifish could make great tank mates.

Distribution: Mayland’s Rainbowfish lives in a limited region in the Mamberamo area of Western New Guinea.  Found upstream from Lake Holmes, it prefers narrow creeks with dense shadowy vegetation and rocky bottoms.

PH: 7.0 -7.5

Temperature: 26°C (79F)

Hardness: 10gH

Description:  Adult male Mayland’s Rainbowfish are olive green to brown on the upper body and silver-white on the lower parts of the body.  Between each horizontal scale row, there is a thin bluish stripe.  Females are usually smaller than the largest male size of 13cm (up to 5 inches).

Diet: A nutritious varied omnivorous diet will keep your Mayland’s Rainbowfish in top form.  Feed regular portions of live food, including insect larvae, worms, insects, bloodworms and shrimps.

Breeding: As far as we know, Mayland’s Rainbowfish has not been bred in aquariums.  Believed to be similar in reproductive habits to Melanotaenia affinis, the safest way is to utilize the information regarding the aforementioned species. Set up a separate breeding tank with lots of fine leaved plants, like java moss, or provide artificial spawning mops. After hatching, the fry should be removed to a separate tank to avoid predation.  Feed on crushed algal flake or baby brine shrimp, and keep them separate until they are ready to rejoin the community tank.

Comments: Mayland’s Rainbowfish is rare in the aquarium hobby, not because it is difficult to keep, but rather that it can be tricky to come by due to the isolated nature of its natural environment.

Should you manage to obtain a Mayland’s Rainbowfish, mimic the natural shadowy habitat of the Mamberamo region by using dim aquarium lighting, providing rocks, submerged driftwood and floating plants.

They should do well in a species or community aquarium providing you adhere to their water chemistry conditions.  Make sure you have a tank large enough for open swimming areas and change the water regularly.

Family: Melanotaeniidae

Distribution: Lake Kuromai Rainbowfish is known only from Lake Kuromai on the Vogelkop Peninsula of Western New Guinea, Indonesia.  As they are lake dwellers, they prefer low currents and clear, clean water.

PH: 6.5 – 7.5

Temperature: 24°C -26°C (75 – 79F)

Hardness: 12 – 16dH

Description: In usual Rainbowfish form, the males are far more attractive than their female counterparts.  The male Lake Kuromai Rainbowfish exhibit a beautiful blue to mauve body with a black midlateral band, silver speckle inflections and red fins.  The females are less colourful although still display the red fins.  They grow up to 7 - 9 cm (2.7 - 3.5 in).

Diet: In the wild, Lake Kuromai Rainbowfish live mainly on insects but will thrive on a wide variety of omnivorous dried, frozen and live food in an aquarium set up.  Live food supplements may include insect larvae or brine shrimp.

Breeding: Set up a separate breeding tank with lots of fine leaved plants, like java moss, or provide artificial spawning mops. After hatching, the fry should be removed to a separate tank to avoid predation.  Feed on crushed algal flake or baby brine shrimp after about 2-4 weeks, and keep them separate until they are ready to rejoin the community tank.   Wait until the fry are large enough before you feed them baby brine shrimp because the latter have been known to try and eat the fry.

Comments: Keeping the peaceful Lake Kuromai Rainbowfish is easy and is a suitable addition to a community or species tank.

Remember that they like clear, clean water so regular water changes are a must.   With their trademark non-aggressive natures, they will do well in a community aquarium.  Keep your tank well-planted, and provide plenty of areas for open swimming and places to hide.   Additionally, keep a low current in your tank as this mimics their natural habitat.

Family: Melanotaeniidae

Distribution: As you would expect, Melanotaenia fluviatilis is endemic to the Murray-Darling River systems in Australia.  You will find them in still or slow-moving rivers, billabongs and creeks, drains, ponds, and reservoirs.

PH: 7.0 – 7.5

Temperature: 22°C – 25°C (72 – 77F)

Hardness: 12 – 16dH

Description: With main body colourations of olive to brown with possible turquoise tinges, the specific colours of Melanotaenia fluviatilis depend on water conditions and location of the particular fish. Their fins are red or clear and can be decorated with light dots.  Occasionally, narrow brown, red or dark stripes can adorn the Murray River Rainbowfish.  They grow to a potential length of 11cm (4 inches) although most only reach 8cm (3 inches).

Diet: A nutritious varied omnivorous diet will keep your Murray River Rainbowfish in top form.  Feed regular portions of beef-heart mix, blood worms, black worms, mosquito larvae, flakes, small pellets and tetra bits to supplement their diet.

Breeding: Breeding is very easy by mimicking the seasonal changes experienced in the wild.  Get your breeding pairs into condition by feeding them larger quantities of live food. Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.

Expect 150-200 eggs to be laid in the morning sun.  The eggs will hatch after seven days and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar.

Comments: The Murray River Rainbowfish is a lively shoaling fish who appreciates the morning sun. They are suitable for community and species aquariums.  Provide a 100cm tank with large open swimming areas, hiding spots created by drift wood and dense plant life, and good filtration for these energetic, yet peaceful rainbows.  Go for a sandy substrate and a very tight fitting lid as these fish jump when startled.

Family: Melanotaeniidae

Distribution: Found in the northern and southern drainage systems of the Markham, Ramu, Sepik and Upper Purari rivers of Papua New Guinea, in areas up to 1525 metres (5000 feet) above sea level, the Highlands Rainbowfish prefer deep, clear backwater streams and pools.

PH: 7.5 – 8.0

Temperature: 22°C – 26°C (72 – 79F)

Hardness: 10-17dH

Description: With a variance of delicate olive or mauve back highlights and silver body flecks, the Highlands Rainbowfish can grow up to 9 cm (3.5 inches) long.  The females are generally smaller and less colourful.

Diet:

Highlands Rainbowfish need a varied diet suitable for omnivorous fish.  Provide a mixture of live and processed foods.  Live meaty foods will keep the colours on your fish vibrant and allow for spawning.  A diet lacking in live meat will result in colour loss.  Highlands Rainbowfish will also eat green filamentous algae, flake, frozen and freeze dried foods.

Breeding:

Start the spawning process by getting your Highlands Rainbowfish into breeding condition by providing them large quantities of live, meaty foods.

Set up a separate breeding tank with lots of fine leaved plants such as Cambomba, Java Moss, or Riccia.  For best results, take the water temperature to its upper echelons of the recommended range and the breeding pair should begin to spawn among plant leaves.  Once hatched, remove the fry to a separate tank to avoid predation.  Raise the slow-growing fry on small live food, such as baby brine shrimp, or crushed flakes.

Comments: Highlands Rainbowfish are easy to keep in a community aquarium.  Provide good filtration, ample sunlight and a 40 gallon well-planted tank for best results.  Highlands Rainbowfish do well in a species aquarium or a large community tank.

Family: Melanotaeniidae

Distribution: Thought to be extinct in 1987, the Lake Eacham Rainbowfish is found in the north-eastern corner of Australia. Their natural habitats are isolated crater lakes and rainforest creeks abundant in dense vegetation and fallen logs.  While they are now extinct from Lake Eacham, they can be found in small populations in Dirran Creek and Lake Euramoo.

PH: 7.0 – 7.5

Temperature: 23°C – 27°C (73 – 81F)

Hardness: Unknown

Description: Melanotaenia eachamensis is not quite as enchanting as other Rainbowfish but displays the characteristic silvery inflections of their species.  Reaching a length of  6.5 cm (2 ½ inches), the Lake Eacham’s Rainbowfish exhibits a silver to olive-brown body, reddish fins and thin horizontal brown stripes.

Diet: The information on Lake Eacham Rainbowfish is limited.  Try keeping them on a mixed nutritious omnivorous diet with a mix of live and dried foods.

Breeding: While this fish is uncommon in the aquarium hobby, and there are doubts whether or not those being circulated as Lake Eacham Rainbowfish are simply lookalikes or actual specimens, it is believed that this species readily spawns in aquariums. You can keep a pair for breeding or 2-3 females per male.

Set up a separate breeding tank with abundant fine leaved plants, like java moss, or provide artificial spawning mops. The eggs will hatch within a week and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar.

Comments: These fish are currently uncommon in the aquarium hobby despite the fact that they are easy to keep.  Keep your Lake Eacham Rainbowfish in 35 litre (10 gallon) well-planted tank, complete with open swimming areas and driftwood.  They would do well in either a species or community tank.

Distribution: The entire geographic distribution of Lorentz’s Rainbowfish is still yet undetermined.  For now, we know that it lives in the Sermoiwai and Tawarin river systems of West Papua, and from Puive Creek in Papua New Guinea.  Current research shows that their preferred habitat includes shadowed, slow-flowing waterways surrounded by dense rainforest.

PH: 7.5 -8.0

Temperature: 26°C -30°C (79 – 86F)

Hardness: 2 – 16dH

Description: One of the bigger Rainbowfish, Lorentz’s Rainbowfish can reach a length of at least 12 cm.  The sides of Lorentz’s Rainbowfish range from blue to silver and the body is brown to olive.  Male fish exhibit a broad black mid-lateral stripe.

Diet: As with most rainbows, Lorentz’s Rainbowfish will eat almost anything.  Provide a combination of protein and vegetable based foods for optimal health.  Live foods can supplement a base of dried or pellet vegetable food.

Breeding:

There are no current records of Lorentz’s Rainbowfish having been bred successfully in the aquarium hobby.

Comments:

Lorentz’s Rainbowfish is very uncommon in the aquarium hobby.  If you wish to do so, try to copy its natural habitat as much as possible by providing low aquarium lighting, an abundance of submerged logs, open swimming areas and floating plants.  Stress is common in this species so make sure hiding spots are plentiful.

Distribution: Another of the critically endangered Rainbowfish, The Lake Wanam Rainbowfish is found in Lake Wanam, a small lake located above the Markham River Valley in Eastern Papua New Guinea.  Its preferred habitat includes clear, shallow waters that are abundant in plant life and sunlight.

PH: 7.5 -8.0

Temperature: 26°C -30°C (79 – 86F)

Hardness: 10-18gH

Description: Graduating from orange to blue/green anteriorally, the male Lake Wanam Rainbowfish colouration doesn’t disappoint.  Metallic green backs and variations of turquoise to black fins continue to delight any Rainbowfish enthusiast looking to brighten up their aquarium.  Lake Wanam Rainbowfish can reach a length of roughly 13 cm (5.1 inches).  These species have very large distinctive fins in comparison to other members of its family.

Diet: As with the majority of other rainbows, a combination of high quality vegetable based food with meaty treats will keep the omnivorous Lake Wanam Rainbowfish in optimal health.

Breeding:

Start the breeding process by getting your Lake Wanam Rainbowfish pairs into condition by feeding them large amounts of meaty live and plant-based foods.

Set up a separate breeding tank with lots of fine leaved plants, like java moss, or provide artificial spawning mops.

The incubating period can be quite long and last up to 14 days. After hatching, the fry should be removed to a separate tank to avoid predation.  Feed on crushed algal flake or baby brine shrimp, and keep them separate until they are ready to rejoin the community tank.   Growth rate is usually slow so be patient.

Comments:

The Lake Wanam Rainbowfish need careful attention after handling and transportation.  Nurse them back to health with meticulous attention to water quality and diet.  They will continue to be extremely sensitive to changes in temperature and water chemistry for the rest of their lives.

Keep your tank dense in aquatic plant life and provide areas for open swimming and hiding spots.  House your Lake Wanam Rainbowfish in no less than a 100L (26 gallon) aquarium.

Family: Melanotaeniidae

Distribution: Known only from Werfyang Creek, part of the Triton Lakes on the southern coast of West Papua, Pierucci’s rainbowfish are found in the crystal clear, rapid flowing waters that run through dense rainforest habitat.

PH: 6.5 – 8.0

Temperature: Unknown although generally 72 – 82F is suitable for most rainbowfish

Hardness: 6-12 dGH

Description: Melanotaenia pierucciae exhibit a main body colour of mauve with a bronze sheen. Body scales have a thin dark outline and black to dark blue stripes enhance their scale rows. They grow up to 8cm and as usual, the females are smaller and less vibrantly coloured.

Diet: Although there is not a lot of information recorded about the specific dietary requirements of this fish, we can infer that it would survive well on a typical rainbowfish omnivorous diet supplemented by live food portions. Feed twice daily.

Breeding: There is scant information available about breeding Pierucci’s rainbowfish in the aquarium hobby.

Try to follow the usual breeding set up for rainbowfish. This includes providing plentiful spawning mops or fine leaved plants for spawning. Elevate the temperature slightly and bring your breeding pair into mating condition by increasing the quantity and quality of live food offerings.

After hatching, the fry should be removed to a separate tank to avoid predation. Feed on vinegar eels and small foods.

Comments: As with other rainbowfish, Pierucci’s rainbowfish is a peaceful, yet lively swimmer. Provide a harmonious balance of hiding places, such as rocks or caves and plant your tank out with abundant plant life. Provide open swimming areas and at least a 30 gallon tank.

This little middle dweller will make a beautiful addition to both community and species aquariums.

Good filtration and frequent water changes are important.

Recommended Compatible Species:

To bring out intense colouration, keep several male rainbows in one tank.

Melanotaenia pierucciae exhibit the usual peaceful temperament of the rainbowfish variety and should be tanked with other similarly sized, non-aggressive fish.

Family: Melanotaeniidae

Distribution: The small, clear, fast flowing streams of Australia’s Northern Territory is home to the majority of the Exquisite Rainbowfish population.  Additionally, Melanotaenia exquisita can also be found in Western Australia’s King George River and in Lake Malkyullumbo in Northern Australia.  It is not unusual for this adorable Australian to be found swimming around in rocky pools after waterfalls.

PH: 7.5 – 8.0

Temperature: 24°C -30°C (75 – 86F)

Hardness: 16 – 20dH

Description: A vibrant mixture of olive and silver comprise the back and lower sections of the adult Exquisite Rainbowfish.  Black and red stripes with dark zigzags, black spotting and bright red fins adorn this truly exquisite native Australian. The Exquisite Rainbowfish grow up to 7cm (2.8 inches).

Diet: A nutritious varied omnivorous diet will keep your Exquisite Rainbowfish in good form.  Use dried food as a base and supplement with live or frozen food.  They are not picky eaters.

Breeding: There is not a lot of information available about breeding Exquisite Rainbowfish in the aquarium hobby.  However, if you follow their usual water requirements and mimic the natural habitat during the abundant wet season, you may be successful. Get your breeding pairs into condition by feeding them larger quantities of live food.  Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.

The eggs will hatch within ten days and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar and keep them separate until they are ready to rejoin the community tank.

Comments: The Exquisite Rainbowfish are generally not hard to keep as long as you maintain the water condition.  Use their natural environment as a template for your aquarium – include hiding spots, plentiful aquatic vegetation and watch the nitrate levels as they are sensitive to it.    Change at least 25% of the water on a weekly basis.  A tank sized at 100cm (3 feet) is suited for the energetic Exquisite Rainbowfish, making sure that there are large areas provided for open swimming.

Rainbowfish are schooling fish and should be kept in groups consisting of at least six individuals, preferably no less than 10-15. Mix it up with enough females to give them a rest when the males are on the chase, but provide enough males to bring out their vibrant colours when they are in competition for female attention. Whilst this is beneficial to the health and wellbeing of the fish, a large school is rewarding for the aquarist because a school of iridescent Rainbowfish is more dramatic to the eye than a few shy fish peeking out from behind dense vegetation.

Family: Melanotaeniidae

Distribution: Melanotaenia oktediensis is currently listed as vulnerable, due to water pollution caused by the Ok Tedi copper mine. Oktedi Rainbowfish is only present in the Ok Tedi River, and respective tributaries, in the Upper Fly River System.  Their habitat consists of dense rainforest vegetation, cool, clear mountain waters and rocky bottoms.

PH: 7.0 – 9.0

Temperature: 22°C -26°C (72 – 79F)

Hardness: 12gH

Description:  With a body combination of copper brown to white or lilac and a dark mid-lateral stripe, the Oktedi Rainbowfish can grow up to 12 cm (4.7 inches).

Diet: In nature, the Oktedi Rainbowfish lives on a diet of algae and ants.  Therefore, in an aquarium environment, a combination meat, including insect larvae and brine shrimp, and plant based food plan would suffice.  Natural algae is beneficial, but always supplement it with vegetable based food.  Don’t feed your Oktedi Rainbowfish dead food because colouration will become less intense.

A nutritious varied omnivorous diet will keep your New Guinea Rainbowfish in good form.  Use dried food as a base and supplement with live or frozen food.  They are not picky eaters and will even nibble at lettuce or spinach.

Breeding: Breeding the Oktedi Rainbowfish can be quite simple if you mimic the natural habitat during the abundant wet season by raising the temperature to the upper echelons of the recommended range. Get your breeding pairs into condition by feeding them larger quantities of live food.  Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.

The eggs should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar and keep them separate until they are large enough to rejoin the community tank.

Comments: The popular Oktedi Rainbowfish is known to be an easy rainbow to keep worldwide.    Use their natural environment as a template for your aquarium – include hiding spots created by rocks and plentiful aquatic vegetation.  Use powerful aeration to mimic the fast-flowing currents of mountain streams.

Change the water regularly and keep nitrate levels low to non-existent.  Oktedi Rainbowfish are active swimmers and will need large open areas for swimming.  They are suitable for both species and community tanks.

Family: Melanotaeniidae

Distribution: Potentially distribuited throughout the southern coast of eastrn Papua New Guinea between the Kemp River and Milne Bay, Melanotaenia parkinsoni were originally collected from a small isolated pool surrounded by grassy plains and rainforest.

PH: 7.0 -8.0

Temperature: 24°C – 30°C (75 – 86F)

Hardness: 8-10gH

Description: Reaching up to 15cm in length, the mature male Melanotaenia parkinsoni can display a magnificent array of colours; silver body, rose-coloured chest and narrow scale row stripes with bright orange fins, often with a ragged appearance. The poor females are rather drab in comparison, being smaller and far less colourful.

Diet: Parkinson’s rainbowfish are easy to feed and will take all leading brands of tropical granular and flake foods. Feed regular portions of live food, including insect larvae, worms, insects, bloodworms and shrimps to keep your fish in top health.

Breeding: Breeding Parkinson’s rainbowfish is very simple. They are prolific breeders and are not fussy about water chemistry. The tricky process is in the raising of the fry, as they are small and grow very slowly.

After hatching, the fry should be removed to a separate tank to avoid predation. Feed on vinegar eels and keep them separate as the parents will eat them. They will require very small food and very clean water. As mentioned, they will be very small so keep them separate for at least a couple of months until they grow larger.

Comments: Parkinson’s Rainbowfish are very hardy fish and as such, are suitable for enthusiastic beginners. Keep your Parkinson’s Rainbowfish in at least a 55 gallon well-planted (fine-leaved plants) tank. They need to swim so allow for open swimming zones, especially in the middle section as that is where they spend most of their time.

They are known to be zippy fish who dart around the aquarium constantly and in their excitement, they have been known to jump so keep your lid securely fixed.

To bring out their colours even more, provide a couple of hours of sunlight per day.

They will adapt well in a single sex/mixed sex species or community aquarium.

Distribution: Found in south western Papua New Guinea, the Fly River Rainbowfish lives in an area that has not been properly surveyed – this doesn’t allow for the full knowledge of its actual geographic distribution. From what we know, the Fly River Rainbowfish is found in the small, clear, lowland rainforest creeks near Kiunga.

PH: 6.1 – 7.5

Temperature: 24°C  – 26°C (75 – 79F)

Hardness: 5 – 8dH.

Description: With a length of up to 7cm and vibrant body colouration ranging from luminescent bronze green to golden yellow with thin black stripes, it is easy to see why the Fly River Rainbowfish has become popular in the aquarium hobby.

Diet: The Fly River Rainbowfish needs a nutritious, varied omnivorous diet.  This could include a base of dried flaked food with supplements of live food, such as brine shrimp or insect larvae.

Breeding: Breeding Fly River Rainbowfish can be quite fruitful if you keep the water temperature within the upper reaches of the recommended range.  This will mimic the abundant wet season. Get your breeding pairs into condition by feeding them larger (than normal) quantities of live food.  Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.

The eggs will hatch within ten days and should be removed to a separate tank to avoid predation.  Feed the tiny fry on baby brine shrimp or vinegar eels and keep them separate until they are ready to rejoin the community tank.   The quality of the young fish can be quite bad so careful selection is reccomended.

Comments: The Fly River Rainbowfish adapts well to aquarium life and is known to thrive well in small 35L (9 gallon) aquariums.  This sized tank will house a group of five fishes quite well.

Mimic their natural environment by providing abundant back and side aquatic vegetation and plentiful floating plant life to shade the Fly River Rainbowfish from the lighting.  Provide good filtration and open swimming areas for a healthy community of Fly River Rainbowfish.

Distribution: The Desert Rainbowfish is found in all the larger rivers systems of arid Central Australia, New South Wales, Queenland, South Australia and the Northern Territory, specifically the Paroo, Warrego and upper Darling rivers.  The Desert Rainbowfish is chiefly an inhabitant of desert streams and reservoirs but has also been located in rocky gorges.

PH: 6.0 – 8.0

Temperature: 20°C – 30°C (68 – 86F)

Hardness: Up to 30dH

Description: Desert Rainbowfish grow up to 10cm and live up to five years.  The males of this unique species of Rainbowfish can be found in two colour forms.  One form displays a purple body with yellow-green fins and a dark speckled border.  The other has a blue-green body and fins.  During breeding, the male’s body turns a beautiful pink.  The female Desert Rainbowfish always have silver bodies and transparent fins.

Diet: Feed the omnivorous Desert Rainbowfish up to twice a day on a nutritious balanced diet of live and processed food.  In the wild they feed on algae, aquatic plants and invertebrates so mimic this healthy combination by providing vegetable-based foods with meaty offerings.  Natural algae growth can also help provide nutrition.

Breeding: Breeding Desert Rainbowfish in aquariums has not yet been recorded. Despite this, you could trigger breeding by mimicking the warm season of its natural habitat.  Start by setting up a separate breeding tank with lots of fine leaved plants such as Cambomba, Java Moss, Mifoil or Riccia.  For best results, take the water temperature to its upper echelons of the recommended range and the breeding pair should begin to spawn among plant leaves.  Once hatched, remove the fry to a separate tank to avoid predation.  Raise the slow-growing fry on small live food, such as baby brine shrimp, or crushed flakes.

Comments: The Desert Rainbowfish is not a common aquarium fish outside Australia and is recommended for the intermediate aquarist.  Simulate the natural environment of the Celebes Rainbowfish as much as possible by providing submerged logs and dense aquatic vegetation.  Provide a well-planted 20 gallon tank to allow for open swimming.

Distribution: The hardy Eastern Rainbowfish is found in almost every freshwater habitat, with a slight preference for clear, slow moving streams.  Geographically, this native Queenslander is found in Rockhampton in Central Queensland, east of the Great Dividing Range, and also along the coast of Queensland from Gladstone to the Normanby River system in Cape York Peninsula .

PH: 5.0 – 8.5

Temperature: 20°C -30°C (68 – 86F)

Hardness: 6 – 15dH

Description: With main body colours of vibrant variances of red, gold and blues, Melanotaenia splendida splendida is sure to delight any keen aquarist.  Typical of all Rainbowfish, the male has a larger dorsal fins, is deeper bodied, more colourful and has a sloped notched forehead than their female counterparts.  The large radiant Eastern rainbowfish can live for five years and grow up to 15cm long.

Diet: Although naturally carnivorous, the Eastern Rainbowfish are easy feeders and will readily accept most omnivorous commercial foods, whether live or frozen.  Feed them high quality flake or pellet food as their staple diet but do offer live food like brine shrimp and blood worms.  Supplement their diet with chopped up, defrosted peas or fresh salad lettuce to fulfil their vegetable dietary needs.

Breeding: Breeding the Eastern Rainbowfish is easy as they are prolific breeders, and are not picky about water requirements.  The only potential problem that you could encounter is in raising the fry. Get your breeding pairs into condition by feeding them higher quality and quantities of live and plant based food.  Set up a separate breeding tank with lots of fine leaved plants or spawning mops. Keep the breeding pair in a species only tank as they will cross breed with other Rainbowfish.

The eggs will hatch within a week and should be removed to a separate tank to avoid predation.  Feed on crushed algal flake or baby brine shrimp and keep them separate until they are ready to rejoin the community tank.

Comments: The hardiest of all Rainbowfish, the Eastern Rainbowfish are specially suitable for beginners. Characteristic traits of peacefulness, active swimming and reflective rainbow colouration will enliven any community aquarium.  Provide plentiful aquatic vegetation, submerged logs and large open areas for swimming.

A tank sized at 55 gallons is best suited for this larger Rainbowfish, and be sure to keep a firm lid on the top of your aquarium to prevent your Eastern Rainbowfish from jumping out of the top.

Family: Melanotaeniidae

Distribution: Melanotaenia solata occurs in the north-western part of the Northern Territory, from the Fitzroy River to the Adelaide River, east of Darwin.  They are also found on the large islands near the Gulf of Carpentaria, including Groote Eyland and Bickerton Island, and in Alligator River in Southern Arnhem Land, Australia.  Typically, the Northern Rainbowfish natural habitat includes vegetation-rich swamps and tannin rich pools in lowland tributaries and floodplains.

PH: 7.0 – 8.0

Temperature: Around 27°C (80F)

Hardness: 10dH

Description: Similar to Melanotaenia splendida rubrostriata in colouration, although paler, the Northern Rainbowfish exhibits a bright red tail, and a silvery-grey body with trademark black and orange to red stripes.   The exact tone and depth of colouration depends on geographic location. They grow up to 12cm; although commonly only reach 10cm.  Females are generally smaller, around 8cm, and are less vibrantly coloured.

Diet: A nutritious varied omnivorous diet will keep your New Guinea Rainbowfish in good health.  Offer small crustaceans, insect larvae and vegetable food like algae.  They adapt well to flakes and granules.

Breeding: It is easy to achieve success when breeding Melanotaenia solata. Get your breeding pairs into condition by feeding them larger quantities of live food.  Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.   Eggs will be laid on the plant matter.

The eggs should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar and keep them separate until they are ready to rejoin the community tank.

Tip: Other fish have been also called Northern Rainbowfish, so be sure to use the Latin name when purchasing this fish otherwise you could go home with the incorrect species.  This is especially important when you are trying to breed Melanotaenia Solata only, not a cross breed.

Comments: The hardy Melanotaenia Solata is generally easy to keep because of their adaptability to pH, hardness and temperature fluctuations.   As long as you keep the tank well-aerated and free of nitrates, then your Northern Rainbowfish should thrive happily. Use their natural environment as a template for your aquarium – include hiding spots created by log debris and plentiful aquatic vegetation, including floating plants.  Provide areas for open swimming.

These fish may jump so be sure to secure a tight fitting lid to your aquarium.

Distribution: A native of Central Papua New Guinea, Lake Kutubu Rainbowfish is yet another member of the Rainbowfish family who is listed as vulnerable on the IUCN Red List of Threatened Species.  Decreasing populations caused by overfishing, habitat destruction and pollution now leaves Lake Kutubu Rainbowfish in a precarious environmental position.

Lake Kutubu Rainbowfish can only be found in Lake Kutubu and Soro River in New Guinea’s Southern Highlands.  Their preferred habitat is clear, alkaline mountain waters rich in plant life.

PH: 7.0 – 9.0

Temperature: 21°C -25°C (70 – 77F)

Hardness: 10-18dH

Description: Brilliant turquoise blue to vibrant greens adorn this beautiful Rainbowfish.  With a golden shine to its back and white underside inflections, the stunning Lake Kutubu Rainbowfish can grow to at least 12cm (4.7inches), making them one of the larger members of the Melanotaeniidae family.

Diet: Lake Kutubu Rainbowfish could live on dried food but for optimum health, activity and colouration, it is best to offer a wide variety of dried, frozen and live food.  This may include insect larvae or brine shrimp.

Breeding: Set up a separate breeding tank with lots of fine leaved plants, like java moss, or provide artificial spawning mops.

The eggs will hatch within 10-12 days and should be removed to a separate tank to avoid predation as the adult fish might eat eggs and fry.  Feed on crushed algal flake or baby brine shrimp, and keep them separate until they are ready to rejoin the community tank.  Growth rate is slow.

Comments: Keeping Lake Kutubu Rainbowfish should be simple as long as you adhere to their specific water requirements.  Refer back to their natural habitat when making decisions about how to set up your tank.

Remember that they like clear, clean water so regular water changes are a must.   With their trademark non-aggressive natures, they will do well in a community aquarium.  Keep your tank well-planted, and provide plenty of areas for open swimming and places to hide.   Due to their size, they may dominate mixed community tanks so aim for an aquarium no less than 75 gallons.

Distribution: Kamaka Rainbowfish are localised to the three Triton Lakes; Lake Kamakawaiar, Lakamora and Aiwaso, which are situated inland from Triton Bay, West Papua.

PH: 7.0 – 8.0

Temperature: 24°C – 27°C (75 – 81F)

Hardness: 6 – 14dH

Description: Melanotaenia kamaka display a flecked silver-blue colouration and blue-black posterior mid-lateral stripes.  The fins are often blue to translucent and a blue-black patch can be present near the upper section of the eye.  Females are usually less colourful and more translucent than the males. Kamaka Rainbowfish are part of the smaller Rainbowfish population; growing up to 6 -7 cm (2.36 - 2.76 inches).  They can be expected to live up to five years.

Diet: Kamaka Rainbowfish will eagerly eat any food offered.  Be sure to offer a mixed nutritious omnivorous diet with a base of flake or pellet food and weekly live or frozen food treats.

Breeding: Kamaka Rainbowfish are quite simple to breed.  Two weeks prior to breeding, get your breeding pairs into condition by feeding them larger quantities of live food. Set up a separate breeding tank with abundant fine leaved plants, like java moss, or provide artificial spawning mops. The eggs will hatch within two days and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar.

Comments: Kamaka Rainbowfish do best in community and species aquariums that provide large open swimming areas as they are extremely energetic.  Cater for their occasionally timid nature by providing hiding spots created by drift wood and dense aquatic vegetation.  Make sure your tank has a tight-fitting lid as they are excellent jumpers.

Diet: A nutritious varied omnivorous diet will keep your Irian Jaya Rainbowfish in top form.  Feed regular portions of live food, including insect larvae, worms, insects, bloodworms and shrimps.

Breeding: Get your breeding pairs into condition by feeding them larger quantities of live food.  Set up a separate breeding tank with lots of fine leaved plants, like java moss, or spawning mops.  Raise the temperature to 75-81°F (24-27°C) and spawning should occur.

The eggs will hatch within ten days and should be removed to a separate tank to avoid predation.  Feed on baby brine shrimp or similar.

Comments: Irian Jaya Rainbowfish are suitable for community and species aquariums.  Provide a 150L (40 gallon) tank with open swimming areas, hiding spots created by drift wood, and good filtration for these energetic, yet peaceful rainbows.  Change at least 25% of the water regularly and keep the organic waste to a minimum.

Rainbowfish are a great community species in terms of their temperament and apart from other Rainbowfish species they also live happily with most Tetra species (particularly the Neon Tetra and Black Tetra). They are also great tank mates with Discus, CorydorasCatfish  (particularly Corydoras Sterbaiand Corydoras aeneus) Angelfish, Clown loach, the common Guppyand Platy and most Gourami(such as the Blue Gourami and Dwarf Gourami like the Honey Gourami) Also can live happily with most Danio(particularly the Zebra Danioand Pearl Danio)  and also many Killifish make great tank mates. One thing you should take into consideration when housing rainbows with these recommended species is the water quality. Temperature and Hardness are similar but P.H. can be quite different, although it is not ideal, if you keep your water at a P.H. of 7 this should keep your community happy.

Rainbowfish are schooling fish and should be kept in groups consisting of at least six individuals, preferably no less than 10-15. Mix it up with enough females to give them a rest when the males are on the chase, but provide enough males to bring out their vibrant colours when they are in competition for female attention. Whilst this is beneficial to the health and wellbeing of the fish, a large school is rewarding for the aquarist because a school of iridescent Rainbowfish is more dramatic to the eye than a few shy fish peeking out from behind dense vegetation.

Family: Melanotaeniidae

Distribution: After being first collected in 1911, this species of Melanotaeniidae are still awaiting rediscovery.  Only two male specimens were originally found in the upper Sermowai River on the north coast of West Papua, about 75 kilometres west of Jayapura.

PH: Unknown – varies significantly according to seasons

Temperature: 18°C -28°C (64– 82F)

Hardness: Unknown – varies significantly according to seasons

Description: The Corona Rainbowfish can grow up to 12cm (4.7 inches).  The dorsal and anal fins are longer than that usually found in other members of the Melanotaeniidae family.  Its live colours remain unknown. Although, we can infer, from the preserved specimens displayed in Amsterdam, that there might have been dark purple stripes on the upper side of its body.

Diet: The Corona Rainbowfish is not known in the aquarium hobby.

Breeding: While the Corona Rainbowfish is believed to be unavailable in the aquarium hobby, it is assumed that its breeding habits are similar to that of other members in its family.

Comments:

This species has not been recorded as having existed in a captive environment.

Family: Melanotaeniidae

Distribution: Glossolepis leggetti distribution is limited.  It has only been found in the deep, clear still pools of the Tiawiwa River, a tributary of the Wapoga River System, in northern West Papua.

PH: Unknown

Temperature: Unknown

Hardness: Unknown

Description: Glossolepis leggetti males are typically stunning in colouration; iridescent green backs, orange to white colouration on breast and lower sides, metallic blue midlateral band and borders with translucent to blue fins.  Females exhibit similar colouration but are less flamboyant. They may reach up to 10cm in length.

Diet: While this species is not currently available in the aquarium hobby, a combination of high quality vegetable based food with meaty treats might serve to mimic the natural diet of Leggett’s Rainbowfish.

Breeding:

As this species is not currently in the aquarium hobby, information about breeding in aquariums is limited.  It is assumed that the reproductive habits of the Leggett’s Rainbowfish would be similar to other rainbows.

Comments:

This Rainbowfish is not currently recorded as being in the aquarium hobby.  Theoretically, mimicking the natural habitat of Leggett’s Rainbowfish will help to create a healthy, suitable aquarium for your specimens.  Use the knowledge gleaned from keeping other rainbows from similar regions – abundant plant life, open swimming areas, hiding spots and nitrate sensitivity – to help improve chances of success.

Black Banded Rainbowfish

Melanotaenia nigrans

Family: Melanotaeniidae

Distribution: The Black-banded Rainbowfish can be found in rainforest streams, lily lagoons and small estuaries that flow through the swampy environments of the northern parts of Australia. While it is known that the Black-banded Rainbowfish prefers habitat located near the ocean, they have been collected 130km (80 miles) from the sea.

Specifically, we know that Melanotaenia nigrans populations occur in Napier Broome of Western Australia, Groote Eylandt of the northernmost tips of the Northern Territory and Cape York Peninsula.

PH: 5.5 – 7

Temperature: 22°C -25°C (72 – 77F)

Hardness: 4- 13gDH

Description: These uniquely slender rainbowfish can be expected to grow between 9 cm (3.54 inch) and 11 cm (4.33 inch). Black Banded Rainbowfish present a greyish brown back with white lower sides. In typical Melanotaenia fashion, the Black Banded Rainbowfish are striking in their dark mid-lateral stripe. This spectacular decoration is more present in the males, who will be larger and more colourful than the females. You can expect to have this eye-catching specimen to have an aquarium life expectancy of 3-5 years.

Diet: Melanotaenia nigrans is an easy feeder as it accepts all foods willingly. For best health and breeding potential, offer a high quality flake product and live food treats such as brine shrimp and white worms.

Breeding: By replicating the rainy season of its natural environment, you have a better chance of successfully breeding your Black Banded Rainbowfish population. This means creating a higher water level, softer and more acidic water, a huge increase of live food and a few more hours of sunlight exposure early in the morning.

Set up a separate breeding tank filled with dense vegetation like java moss or artificial spawning mops. Keep the water at the higher end of the recommended range and the eggs will hatch in a week. It is advisable to move the spawning medium into a different container to avoid predation.

Comments: Keep these passive species of Rainbowfish in either a community aquarium of other small and peaceful fishes or in a species aquarium. As they are naturally a schooling fish, make sure you keep at least six companions in the tank. As with other rainbowfish varieties, they thrive in a well-planted tank with an abundant of open swimming areas and hiding spots.

In the wild, Melanotaenia nigrans steer clear of powerful currents so mimic this in their aquarium habitats for best results.

Tip: It has been known for some aquarium shops to sell a closely related species, the Melanotaenia duboulayi, while claiming they were selling Melanotaenia nigrans. To avoid this, do your research and only buy from reputable sellers.
