Origin[edit]
- Asia and Oceania: central-southern New Guinea and northern Australia.
Sexing[edit]
- The male has more elongated dorsal and ventral fins. These fish can be difficult to breed in captivity as the tiny fry are difficult to feed and keep alive.
Tank compatibility[edit]
- An entirely peaceful fish that is vulnerable to being fin-nipped. Keep this fish in groups of its own kind, with more females than males. Multiple males will mean you see the best colours as they will display to each other.
Diet[edit]
- Best fed on small live food such as daphnia and tubifex, may also learn to accept flake and pellets.
Feeding regime[edit]
- Feed once or twice a day.
Environment specifics[edit]
- Appreciates a densely planted mature tank with good filtration but not too strong a current.
Behaviour[edit]
- An active peaceful fish. Males may chase each other and display.
Identification[edit]
- A distinctive little Rainbowfish, with an elongated pointed body, the dorsal, anal and caudal have very long extended rays, giving the fish it's common name. The body is coloured iridescent yellow/green with hints of blue. The fins can vary in colour.
