Acanthurus achilles

Acanthurus achilles naturally inhabits the Pacific Ocean. Large aggregations of these fish are observed along the coasts of the Marquesas Islands, Great Barrier Reef and Hawaii, as well as in the coastal areas of Micronesia and Polynesia. Small numbers of fish are found along the western coasts of Central and North America. Fish prefer to stay along the outer slopes of reefs, in quiet lagoons with crystal-clear water at a depth of 10 m. If the habitat of these fish are rich in food, then Achilleas form large flocks, otherwise live singly, taking a fancy to a particular part of the coral reef and protect it from other tribesmen. Fish are recommended for keeping only experienced aquarists.
