Surgeons and Triggers

We stumbled across this awesome school of convict surgeonfish (Acanthurus triostegus) and black-finned triggerfish (Melichthys indicus) while on a recent snorkel on a coral reef. These fish play a vital role in reef health by constantly grazing on algae and coral. Triggerfish quite often eat parts of the coral skeleton which pass through the fish and come out the other end as coral sand.
