Acanthurus polyzona

Acanthurus polyzona, commonly known as the black-barred surgeonfish or zebra tang, is a tropical fish found in coral reefs in the western Indian Ocean. It was first described in 1868 by the Dutch ichthyologist Pieter Bleeker, who gave it the name Rhombotides polyzona; it was later transferred to the genus Acanthurus, becoming Acanthurus polyzona.
