Banded Butterflyfish

Thick black vertical stripes — two on their sides and a third extending from their dorsal fin to their caudal peduncles (tails). Their pelvic fins, except for the spine, are also black. A well-known denizen of commercial aquariums, this species has a short snout and a vertically flattened, squarish "disk-shaped" body. They have 12 dorsal spines, 19 to 21 dorsal soft rays, 3 anal spines, and 16 to 17 anal soft rays. Adult banded butterflyfishes grow to a maximum length of about 15 cm. Maturity is reached at lengths around 12 cm.
