Lined butterflyfish may grow up to 30 cm (nearly 12 in) long, which among Chaetodon is matched only by the saddle butterflyfish (C. ephippium), making them about as big as dinner plates. They are white in color, with thin black vertical bars which join a thick black band at the base of the tail and dorsal fin. The tail, dorsal, and anal fins are yellow. This uncommon fish is found in pairs or swimming alone, or occasionally in spawning aggregations. It occurs between 2 and 50 m depth, in coral-rich areas of reefs and lagoons. Coral polyps, small anemones, algae and invertebrates make up their diet. Learn more about Lined Butterflyfish
