Description

The eightband butterflyfish is a butterflyfish of the family Chaetodontidae from the Indo-West Pacific. The species grows to about 12 cm and has a deep, yellow-white, disc-shaped body with eight narrow, dark vertical bands. It swims in pairs in coral-rich parts of sheltered lagoon and inshore reefs; juveniles stay in groups among branching coral. As a specialised coral feeder it feeds almost exclusively on coral polyps, making it highly dependent on healthy coral. Owing to this specialisation it is difficult to keep in the aquarium. The species is harmless to humans.
