Sexing[edit | edit source]

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.


Tank compatibility[edit | edit source]

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.


Diet[edit | edit source]

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


Feeding regime[edit | edit source]

Feed once or twice a day.


Environment specifics[edit | edit source]

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


Behaviour[edit | edit source]

Prefers the company of others. Keep in a shoal.


Identification[edit | edit source]
