The rainbow shark (Epalzeorhynchos frenatum) is a popular freshwater community-tank aquarium fish of the Cyprinidae family. It is also variously known as the ruby shark, red-fin shark, red-finned shark, rainbow sharkminnow, green fringelip labeo, whitefin shark and whitetail sharkminnow. Unlike true sharks, which belong to the cartilaginous fishes, the rainbow shark is a bony fish.

The back edge of the male's dorsal fin ends in a point and the female's forms a right angle. Rainbow's have been bred in captivity, but the success rate is low due to their lack of intolerance for each other.
Additional Comments
Juveniles need a lot of vegetation in their diet to promote proper growth and coloration. Without a proper diet their colors fade and their growth is stunted.
