Brown Surgeonfish

Found in small to large schools, over hard substrates, and lower surge zones, of shallow lagoons and seaward reefs. This fish is brown to purple-brown with small orange spots on the head and thorax. There is a black spot either side of the tail and a line near the tail.The tail looks purplish in natural light.

Surgeonfish have a blade like spine in the tail that points outwards when bent, unicorns have two hook-like plates along the tail, these are used for defence and are as sharp as a surgeons scalpel, hence the name "Surgeonfish".
