Blue Tang (Acanthurus coeruleus )

The Blue Tang (Acanthurus coeruleus ) is a species of the family Acanthuridae. Since the first yellow as juveniles animals are blue later, they are also called late Blue Surgeonfish.

The animals usually live in coral and rocky reefs in shallow water to a depth of 20 meters, or seagrass beds. In Ascension in the central South Atlantic, there is an isolated population.
