This animal is available captive bred
- Asia and Oceania: central-southern New Guinea and northern Australia.
- 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.
- 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.
- Best fed on small live food such as daphnia and tubifex, may also learn to accept flake and pellets.
- Feed once or twice a day.
- Appreciates a densely planted mature tank with good filtration but not too strong a current.
- An active peaceful fish. Males may chase each other and display.
- 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.
