Overview: Peaceful, active fish. Rainbowfish are generally hardy and easy to care for. Rainbowfish are truly unique in that the males of most species have a bright iridescent strip running from the top of the mouth up over the ridge of the back and continuing to the dorsal fin. Males frequently "flash" this bright strip on-and-off in absolutely stunning displays. When they flash, it looks like a neon light is being turned on and off. This, combined with the amazing coloration of many species, is something truly special that is not to be missed. Fortunately, these fish display and flash frequently. Setup Considerations: Most Rainbows of the Melanotaenia, Glossolepis, and Chilatherina genre grow to 5" - 6," maybe even more on the largest species. Many people successfully keep rainbows in tanks that are around 3 feet long...it can be done. However, these fish are rapid swimmers and do best in a tank that is at least 4 feet long (the length of a standard 55 gallon aquarium). If your tank is smaller, we would recommend sticking to the dwarf species which top out at around 3-3.5" or less. Alternatively, looking into the closely related Pseudomugil genus (commonly called Blue Eyes) might yield the perfect species for a small aquarium. Diet: Omnivore Rainbowfish are easy to feed. They are not picky and will greedily and rapidly eat most standard aquarium foods, small pellets, flake, live and frozen foods like bloodworm as a treat
