Blue-lined Surgeonfish

Acanthurus lineatus


Largish surgeonfish with adults reaching 35cm. Yellow sides with black and blue stripes running basically horizontally, although one stripe runs perpendicularly at the base of the tail and several, diagonally over the gill plates. The ventral section is a solid blue. The tail has a lighter panel and the dorsal, anal and caudal fins have an electric blue outer edge. The forward pointing 'scalpels' at the base of the tail are poisonous in this species.


Most often found in shallow water at reef edges. This one found off Komodo Island in Indonesia.


Although very territorial, this fish was found at a Cleaner Wrasse cleaning station and seemed to tolerate others in close proximity during the cleaning process.
