Slender Filefish

Found singly or in pairs, drifting vertically, and blending in with their surroundings, amongst the branches of gorgonians, over rock and sandy bottoms, of coral reefs. Colour varies to blend in with surroundings.

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.
