Eightband Butterflyfish Video Stock Footage
This small butterflyfish grows to a maximum of 12 cm long (nearly 5 in). Its body is white, shading into yellowish on the belly. It has 7 black vertical stripes over head and sides and one centrally on the snout. The third line extends onto the ventral fins. There is a strong black margin on the aft dorsal and anal fins. It is a close relative of the Golden Butterflyfish (C. aureofasciatus) and less close to Rainford's Butterflyfish (C. rainfordi). Probably including the Three-striped Butterflyfish (C. tricinctus) also, these diverse but always high-bodied species make up the subgenus Discochaetodon, of which C. octofasciatus is the type species. They appear to be close relatives of the subgenus Tetrachaetodon which includes for example the Mirror Butterflyfish (C. speculum) and together with these would probably go in Megaprotodon if Chaetodon is split up.
