The Powder Blue Tang may be one of the most striking Acanthurids, native to Africa, Sri Lanka and the Maldives. It’s iconic oval shape, vivid markings, shades of blue and bold yellow dorsal fin make the Powder blue tang a unique addition to any large fish only with live rock or reef aquarium. Like some other tangs and Acanthurus species, the Powder blue tang is very susceptible to ich and other skin parasites. We recommend quarantining tangs to ensure they do not introduce such parasites into a main display aquarium.
