Scientific name: Bedotia geayi
The Madagascan Rainbowfish grows to 3.5 inches and should be kept in a tank with ample swimming space. This active, hardy shoaling fish spends almost all of its time near the surface; it's a good choice for filling the upper levels of the aquarium. It likes to jump, too, so a secure lid is necessary.
A water temperature in the range of 72º to 78º Fahrenheit, a pH between 7.0 and 8.0, and moderately soft to relatively hard water provide the best environment. All flake and freeze-dried foods can be used, but live brine shrimp should also be in its regular diet.
