The Kole Tang (pronounced Coal-e in Hawaii), a.k.a. Yellow-eye Tang, is deep brown with horizontal yellow stripes running along its body. These Tangs have large eyes that are circled in bright yellow. They are one of the shyest of all the Tangs and like lots of rockwork to hide in. They are very hardy and make excellent additions to larger reef tanks. While they can be kept in groups they can be aggressive towards each other and should be kept singly. They are voracious algae eaters.The Surgeonfish family consists of fish which are colorful, thin-bodied, and usually have an oval shape. These fish have long continuous dorsal and anal fins and crescent tailfins. The scalpel at the base of their tailfin is very sharp and is used by the fish for protection from predators as well as a way of establishing itself with other fish. These fish are usually seen at reefs eating algae all day long.Photo by Saltwaterfish.com member, Renogaw: Michael Wagoner.
