The Auriga Butterflyfish, also known as the Threadfin Butterflyfish, is one of the more popular and readily available butterflyfish. Generally a hardy species, in the wild it is found on inner and outer reef slopes. As with many fish, the Threadfin Butterfly's colour and markings can vary with the region of origin. Its body is white with 'chevron' markings on the side. Tear edge of the dorsal fin has a prominent black spot, and a prominent black vertical band runs through the eye. The rear of soft-dorsal fin has a trailing filament, and it has a belly patch of descending oblique dark lines as well as bright yellow fins. Red Sea specimens tend to lose the eyespot (false eye to confuse predators) on the dorsal fin.
