Rasboras

Family: Cyprinidae

Distribution: Rasbora sarawakensis, commonly known as Sarawak Rasbora, is an Asian freshwater species found in Borneo and Sarawak, Malaysia.  It is also distributed in the West Kalimantan province in Indonesia, and the Mempawah and Melawi, in Kalimantan Barat.  It usually resides in slow forest streams littered with thick vegetation.

PH: 6.0 – 7.5

Temperature: 22°C – 26C (72 – 78F)

Hardness: 2 – 12 dH

Description: Rasbora leptosoma can reach a maximum length of around 4 cm.  It is a highly desirable species with a great array of colours; it has orange fins and a silver and electric blue midline.  Females are much more round-bellied and generally a bit larger than males.

Diet: This species probably eat invertebrates in the wild, but has a preference for dried foods in an aquarium environment.  You can feed it Daphnia, bloodworm and other live foods to prime it for breeding and also to bring out its best colours.

Breeding: Rasbora sarawakensis will spawn often when in good condition but, like most cyprinids, this egg-scatterer exhibits no parental care.  You should provide a mesh at the base of your tank for the eggs to fall through out of harm’s way, so as to stop them being eaten by the parents.  You could introduce a well-conditioned group of adults to a 30 litre tank that is only half-filled with water; spawning can be initiated by added small amounts of cold water every few hours.  The eggs will hatch in 18 – 48 hours; the fry will be swimming within the next 24 – 48 hours..

Comments: You can house a small group of Rasbora sarawakensis in a 70 litre tank.  Your tank should have plenty of open swimming space in the middle of the tank and a dark substrate to allow it to demonstrate its best colouration.  A cover of floating plants, along with some driftwood branches and a weak level of filtration, is recommended.  Sarawak Rasbora is reportedly tough to breed and requires a moderate level of care, making it better suited to hobbyists with some experience.

Recommended Compatible Species: This peaceful, schooling fish can get nervous unless it is housed in groups of 8 – 10.  Serawak Rasbora will live happily with most Tetra species (particularly the Neon Tetraand Black Tetra). They are also great tank mates with DiscusApistogramma‘s like Apistogramma Cacatouides and Apistogramma BorelliCorydorasCatfish  (particularly Corydoras Sterbai and Corydoras aeneusAngelfishClown loach, the common Guppy and Platyand 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.
