Common name: Butterbun

General information

Poey's Butterflyfish, scientifically known as Prognathodes aculeatus, is a vibrant and attractive species that adds a splash of color to any marine aquarium. This species is distinguished by its elongated snout, which it uses to pick food out of crevices in the reef. The body is primarily yellow with a dark vertical band running through the eye and another at the base of the tail, which are characteristic features of this fish.

Care

The Longsnout Butterflyfish is considered moderately difficult to care for due to its specialized dietary requirements. It thrives in a well-established reef tank with plenty of live rock for grazing and hiding. This species typically feeds on a variety of small invertebrates and algae in the wild, so a varied diet including marine meats and algae-based foods is essential for their health in captivity.

Reproduction

In the wild, Prognathodes aculeatus forms monogamous pairs during the breeding season. They are pelagic spawners, releasing their eggs and sperm into the water column where fertilization occurs. The larvae are planktonic, drifting with the currents until they develop into juveniles and settle on the reef.

Habitat

Native to the Western Atlantic, Poey's Butterflyfish can be found from Bermuda and the northern Gulf of Mexico to the northern coast of South America. They prefer coral-rich areas and steep outer reef slopes, typically at depths ranging from 20 to 165 feet. In the aquarium, they require ample space to swim and a well-structured environment that mimics their natural habitat.
