Sailfin Tang (Zebrasoma veliferum)

This fish is found in lagoons and seaward reefs from the lower surge zone to a depth of over 100 feet in the Pacific Ocean from Indonesia to the Hawaiian Islands, north to southern Japan and south to the southern Great Barrier Reef. Its diet is composed mainly of leafy macroalgae but will also feed on small, sparsely scattered algae and small growths in crevices.

Tangs are members of the surgeonfish family. Surgeonfish are usually colorful, thin bodied, and 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 along reefs grazing on algae throughout the day.
