Family: Characidae
Distribution: Hyphessobrycon isiri is found in the Uruguay River basin, Argentina, South America. In one area it was located in two ponds on a farm that had a primary substrate of gravel and rock (with sand and mud in between), minimal current and moderate vegetation. These ponds had no light diffusion.
PH: 6.0 – 7.5 pH
Temperature: 22 – 28 °C (72 – 82 °F)
Hardness: 2 – 15 dH
Description: Hyphessobrycon isiri is identifiable by a humeral spot that is perpendicularly elongated and a dark stripe that begins at the caudal fin (thick) and fades out before the humeral spot (thin).
As this species is so uncommon in the hobby, there is a lack of data such as colouration and specific social behaviours. The family is generally peaceful, active and non-aggressive and there is no indication that Hyphessobrycon isiri will be any different. They are good additions to any community or species-specific tank.
Diet: Hyphessobrycon species thrive on omnivorous diets. Your Hyphessobrycon isiri will enjoy a diet that is primarily flakes or pellets with occasional live foods as treats.
Breeding: Due to its rarity, successful captivity-bred reports have yet to be unearthed. If you manage to find a pair and want to try it yourself, it is suggested you follow the general Hyphessobrycon method.
First separate a male and a female (at least one year old) into two conditioning tanks. Feed them live foods for about three weeks before introducing them into the breeding tank. They should breed within 24 hours, but give them three days and, if no eggs appear, repeat the conditioning process.
Remove the parents once they have spawned or you may find they’ve eaten all the eggs. They will hatch after 24 hours and the subsequent free-swimming fry should be fed Infusoria. Once they are big enough, start them on baby brine shrimp.
Err on the side of caution and keep the eggs of Hyphessobrycon isiri in as much dark as possible as it is unknown whether they are light-sensitive or not.
Comments: Hyphessobrycon isiri is uncommon in the hobby and therefore there is limited information available. Consequently, information pertaining to the Hyphessobrycon species in general has been included.

Recommended Compatible Species: They should live happily with other 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.
