General information
The Bank Butterflyfish, scientifically known as Prognathodes aya, is a lesser-known species in the aquarium trade, primarily due to its deep-water habitat and relative rarity. This species is characterized by its deep-bodied form, striking coloration of yellow, black, and white, and its elongated snout which is useful for picking food out of crevices.

Care
Bank Butterflyfish are considered to be moderately difficult to care for, mainly because they require a well-established aquarium with stable water conditions. They are best suited for larger tanks that can provide ample swimming space and rockwork for hiding. Their diet should include a variety of meaty foods, such as mysis shrimp and finely chopped seafood, as well as some vegetable matter.
Reproduction
Little is known about the reproductive habits of Prognathodes aya in the wild or in captivity. Like many butterflyfish, they are likely to form monogamous pairs and engage in elaborate courtship displays.
Habitat
Prognathodes aya is typically found in deeper waters of the Western Atlantic, ranging from North Carolina to the Gulf of Mexico and down to the northern coast of South America. They are often associated with steep reef walls and drop-offs.
