The Powder Brown, a.k.a White Faced Tang, is a very beautiful fish that is mostly chocolate brown with a white face and a bright yellow border running along the base of its dorsal and anal fins. The anal and dorsal fins are black with the dorsal having an orange stripe and the tailfin being white. The Powder Brown prefers lots of swimming room and will do well in either a community or reef tank. Keep only one per tank. 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, zanclus: John Scott.
