Bank Butterflyfish, Chaetodon aya

The bank Butterflyfish (Chaetodon aya) is a species of butterflyfish found in tropical Atlantic waters. It is uncommon through much of its range, being found only on natural and artificial reefs in Florida, the Gulf of Mexico, and off the Yucatan Peninsula. It is also found north to North Carolina.

This silver-white colored fish has yellow on all fins except the pectoral fins. It also has vertical dark bars on its eyes and near the caudal fin. The adult is 5.9 inches in length.

This is a popular fish in the aquarium trade, however, it is best kept in tanks bigger than 55 gallons; 100 gallons or bigger if a second butterflyfish is introduced. It feeds on most aquarium foods, frozen preparations, finely chopped seafood, brine shrimp, dried krill, and flake food. It may nip at soft coral polyps and gorgonians, and will eat any tubeworms. It may also nip at polyps on stony corals.
