Description

The copperband butterflyfish is a butterflyfish of the family Chaetodontidae from the western Pacific. The species grows to about 20 cm and has a deep, white, disc-shaped body with four orange (copper-coloured) vertical bands and an eyespot at the rear of the dorsal fin that misleads predators. Characteristic is the very long, tweezer-like snout, with which it picks food from narrow crevices of rock and coral. It occurs along rocky shores, coral reefs, estuaries and silty inshore reefs, often solitarily or in pairs. As an omnivore it feeds on small invertebrates, worms and coral polyps. The species is harmless to humans.
