Overview: A very underrated rainbowfish. They start as a plain silver looking fish and transform into a magnificent red and green fish.
Setup Considerations: Most rainbows of the Melanotaenia, Glossolepis, and Chilatherina genre grow to 5" - 6". 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 few species which top out at around 3" or less. Alternatively, looking into the closely related Pseudomugil genus (commonly called Blue Eyes) might yield the perfect species for a small aquarium.
Specific Care Requirements: They can jump, so a lid is highly recommended.
Diet: Rainbowfish are easy to feed. They are not picky and will greedily and rapidly eat most standard aquarium foods. However, they can develop problems when fed large, hard food as these foods seem to sometimes damage their mouths/throats. We find it best to feed "soft" foods like flakes, frozen foods, Repashy, and the like. If pellets are fed, they should be very small (think Xtreme Nano or Hikari Micro Pellet size) or softened by being soaked in water before they are fed.
