The Blue surgeon (Paracanthurus hepatus) is a saltwater fish of the family Acanthuridae that grows up to 31 cm.
Description
The blue tang is a brightly coloured reef fish of the surgeonfish family (Acanthuridae) from the Indo-Pacific, known worldwide as 'Dory' from animated films. The species grows to about 31 cm and has a deep, royal-blue body with a black palette-shaped pattern and a yellow tail. It lives on clear, current-swept terraces of seaward reefs, often in loose groups, and shelters among coral when threatened. As an omnivore it grazes mainly plankton and algae. Like all surgeonfishes it bears a sharp, scalpel-like spine on each side of the tail base that can give deep cuts; never grab the fish by the tail.
