Description

The bluestripe butterflyfish is a butterflyfish (Chaetodontidae) endemic to the Hawaiian archipelago. The species has a yellow body with oblique blue stripes, a black spot near the nape and no eye band, which makes it unmistakable. It lives on rocky and coral-rich reefs, often into deeper water. As an omnivore it picks the tentacles of tubeworms, small invertebrates and algae. It lives solitary or in pairs. The species is harmless to humans.
