[edit] Sexing

Males are more brilliant and have more red in their fins, particularly the dorsal. Large males may develop a humpback as they mature. Females have more brown in their scales, whereas males are silver-blue.

[edit] Tank compatibility

A peaceful sociable fish that should be kept in shoals of 6 or more, at least 2 females per male. Do not keep with long-finned fish, will otherwise cohabit happily with other peaceful community fish.

[edit] Diet

Will accept most foods including pellets and flake as well as live food like bloodworm and daphnia.

[edit] Feeding regime

Feed once or twice a day.

[edit] Environment Specifics

Lightly planted tank. They are fast-swimming and truthfully do better in 100L (26.4 US G.)+. Expert jumpers, they do best in a community tank of a large school. Potential fin nippers if only because they are so fast!

[edit] Behaviour

Prefers the company of others. Keep in a shoal.

[edit] Identification

Typical Rainbowfish body shape, but substantially smaller than other Rainbowfish. Has an exceptionally deep body for such a small fish. Dorsal, anal, and caudal fins are all a rich red in colour, the body is iridescent silver with blue hues.
