Found singly over rubble, seagrass beds and weedy areas of shallow coral reefs.
They feed on crustaceans, molluscs and worms.
Colour and pattern variable but usually has a dark V shaped marking on mid-side.
Length - 14cm
Depth - 1-25m
Widespread Indo-West Pacific

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. Ref: https://www.fishbase.se/summary/7849
