The Eritrean butterflyfish or crown butterflyfish (Chaetodon paucifasciatus) is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is essentially just known from the Red Sea and the Gulf of Aden, but has been reported from East Africa. It grows up to 14 cm (5.5 in) in length. It is white with black chevrons, except for a red zone stretching from the aft dorsal fin across the caudal peduncle to the end of the anal fin. A red bar runs vertically through the caudal fin. There are black eyestripes and a black "crown" with white border.
Eritrean butterflyfish are oviparous fish forming monogamous pairings during breeding. They are usually found in pairs or in small groups over coral and rubble areas from 1m to 30m depth. They feed on coral polyps, gorgonians, algae, polychaete worms and small crustaceans. This fish fares well in the aquarium and thus is sought after by hobbyists.
