Rainbow fish are fascinating creatures. They are fast swimmers, brightly colored and it’s fun to watch a group of them traveling across long aquariums. Rainbow fish are in with many other fish species called Cyprinids. Cyprinids have Barbs, Rainbows and goldfish type fish within that grouping. Rainbow fish are in their own groupings that have several “family” groupings such as Melanotaenia (Australia and New Guinea), Caimsichthys, Chilathernia, Glossolepis, Rhadinocentrus, Iriatherina ”Thread Fins” (Australia and New Guinea) Bedotia (Madagascar), Telmatherina (Celabes Rainbow) and the Blue Eyed Rainbows Pseudomugil, Kiunga and Scaturignichthys.
