Chaetodon striatus also commonly referred as the Banded butterflyfish is associated with tropical marine reefs in the Western Atlantic, it can be found from Massachusetts/USA to Rio de Janeiro, Brazil, including the Gulf of Mexico and Caribbean Sea. In the Eastern Central Atlantic it is found off St. Paul's Rocks.
The Banded butterflyfish is very easy to recognize by his thick black vertical stripes, two on the side and a third extending from the dorsal fin to the caudal peduncle, stretching down its silvery body. The pelvic fins, except for the spine, are also black. Chaetodon striatus grows to about 16 centimeters in length and has a short snout and a vertically flattened, squarish "disk-shaped" body. Adult species grows to a maximum length of about 15 cm. Maturity is reached at lengths around 12 cm.
Chaetodon striatus feeds primarily on polychaete worms, coral polyps, crustaceans and mollusk eggs. Adults may form plankton-feeding aggregations of up to 20 individuals, and occasionally clean other reef fishes. It is a diurnal species, active during the day and sleeping at night.
The Banded butterflyfish nonetheless presents one small problem to aquarium keepers, its strange diet is difficult to reproduce in a tank.
Butterflyfish are not recommended for reefs as they will pick at or eat a wide variety of corals, fan worms, and other invertebrates. Most Butterflyfish are known to pick at Aiptaisia, a parasitic anemone.
