Overview

Found in pairs or small schools, in the arms of branching corals, over lagoons and seaward reefs.
They feed exclusively on Acropora polyps.

Filefish can alter their colour and pattern to match their surrounds and so deter predators.
Although closely related to the Triggerfish, their "trigger spine" cannot be locked into place.
