Bignose Unicornfish

Found singly, pairs, or in small schools, sometimes congregating in large caves during the day, or over deep drop-offs, of lagoons and seaward reefs. Adults change all the time from pale to dark. These fish love to play in divers bubbles.

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".
Some species are venomous.
