Potter's Angelfish

Endemic to the Hawaiian archipelago, Potter's angelfish is found in higher densities inside Molokini than almost anywhere else in its range, grazing algae and detritus from the crater's basalt substrate. Its deep orange body fading to blue-grey distinguishes it from all other Pacific angelfish, and its strict endemism makes Molokini one of very few places on earth where it can be reliably observed.
