The Blue surgeonfish ( Acanthurus coeruleus ) is a kind from the family of surgeonfish . As the young fish, which are yellow at first, later turn blue, they are also called late blue surgeon fish .
He lives in the tropical west Atlantic, in the Gulf of Mexico and from Bermuda and the Florida coast to Rio de Janeiro . The animals mostly live on coral and rock reefs, in shallow water to a depth of 20 meters, or over sea grass meadows. There is still an isolated population at Ascension in the central South Atlantic. They reach a size of up to 37 cm.
The juvenile fish are loners who defend their territory with algae stocks. From a length of ten centimeters they turn blue and form small groups. They nomadize through the reef and penetrate with their majority in the territories of the algae-eating damselfish of the genus Stegaster in order to plunder their algae gardens. Experienced aquarists can easily keep them in aquariums from 1500 l.
