Active and social, and most settled when kept with its own kind.
Keep a group of at least 6, and more if you can. Larger groups are calmer and show better colour and behaviour.
Not territorial, although males may spar and display.
Suits a community of similar-sized, peaceful fish that like the same water. Avoid large predators, which will treat it as food. It is likely to eat shrimp.
Fairly tolerant of different water, if it is clean and stable.
A colour form of the splendid rainbowfish that eats insects and some algae. Feed flake, pellets and frozen foods.
Feed small amounts, and remove anything left after a few minutes.
An egg scatterer with no parental care. Adults eat eggs and fry, so use a separate tank with fine plants, moss or mesh on the bottom, and remove the adults after spawning. The fry need very small foods at first.
