Bennett's Butterflyfish can be recognised by its distinctive colouration. It is yellow with light blue bands curving across the lower sides of the body. A blue-edged black bar passes through the eye.
This species grows to 20cm in length. It eats coral polyps.
Bennett's Butterflyfish is found throughout much of the Indo-West Pacific. In Australia it is recorded from the offshore reefs of north-western Western Australia and from the entire length of the Great Barrier Reef.
