Overview

Found in pairs, over sheltered lagoons and inshore reefs rich in coral growth.
They feed exclusively on coral polyps.
Juveniles found in schools in the arms of Acropora corals.

Asian Pacific often white with blackbars.

Butterflyfishes have very fine hair like teeth that enable them to pick out small organisms inaccessible to most other fish for eating.
They thrive mainly on a diet of coral polyps, tentacles of featherdusters and Christmas-tree worms. As these food sources all zap back into their shells, butterflyfishes need to be able to hover motionless while picking at the coral and to dart swiftly over short distances to get the worm before it retracts. They do this by using their Pectoral fins as oars to brake, sprint, turn and even reverse.
