Boesman's Rainbowfish
Shirlie L Sharpe

Native to Australia and New Guinea, Rainbowfish have rapidly become popular world-wide.  Their bright colors and dual dorsal fins set them apart from many other freshwater species.  Unfortunately, their attractiveness has caused some species to be captured to the point of near extintion in the wild. As a result some species, such as the highly prized Boseman's Rainbow, are largely captive bred.

Some of the fish included in this group are:  Axelrod's Rainbow, Boesman's Rainbow, Lake Kutubu Rainbow, Lake Wanam Rainbow, Madagascar Rainbow, Neon Rainbow, and the Red Rainbow. Visit the Rainbowfish gallery for a full list.
