Family Acanthuridae

The family Acanthuridae comprises of the tangs, surgeonfish and unicornfish. They are mostly tropical and typically associated with coral reefs. While the majority of species graze on algae, large schools of some species can be seen hovering in the current over coral reefs gleaning zooplankton. The name surgeonfish stems from their possession of a razor sharp caudal spine either side of the caudal peduncle. They can use this to slash at predators or unwary fishermen. Currently there are 82 species in six genera (Fishbase).

I have seen a school of tangs convict tangs move into an "algal farm" being tended by a gregory (Stegastes species) and wreak substantial damage before the damsel was able to drive them away.
