Astrapogon stellatus is a species of ray-finned fish in the family Apogonidae, the cardinal fishes. It lives in the tropical western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. It is commonly known as the conchfish because it typically conceals itself in the mantle cavity of a living queen conch (Aliger gigas) by day. [3]
Cardinal fishes have large eyes, a large mouth, two widely separated dorsal fins, a long caudal peduncle and large scales. [4] A. stellatus grows to a maximum standard length of 8 cm (3 in). [5] It is dark brown or black, but also has a pale phase, and can be distinguished from related species by its pigmentation and meristics. [6]
A. stellatus is native to the tropical western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. Its range extends from Florida, Bermuda and the Bahamas to the Greater and Lesser Antilles, and Brazil, as far south as Rio de Janeiro. It typically inhabits reefs and clear shallow waters to a depth of about 40 m (130 ft). [1] [5]
A. stellatus is a cryptic, nocturnal species, and feeds on plankton in the open sea. Usually a solitary fish, a pair bond is formed at breeding time. The male is a mouth-brooder, retaining the eggs in his mouth until they hatch, but otherwise, very little is known about the fish's biology. [6]
A. stellatus has a commensal relationship with the queen conch (Aliger gigas), living by day within the mollusc's mantle cavity, and emerging at night to forage. The queen conch is becoming increasingly rare because of over-fishing, and the conchfish has been reported using the rigid pen shell (Atrina rigida) as an alternative refuge. [3] Also amber pen shell (Pinna carnea) is sometimes used. [1] Other members of the family take refuge in corals, sponges and rock crevices. [6]
The black sea bass is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae which is part of the family Serranidae, which also includes the groupers and anthias. It is found in the western Atlantic Ocean, where it is an important species for commercial and recreational fisheries.

Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may generally refer to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 26 extant, and 10 extinct genera.
Aliger gigas, originally known as Strombus gigas or more recently as Lobatus gigas, commonly known as the queen conch, is a species of large sea snail, a marine gastropod mollusc in the family of true conches, the Strombidae. This species is one of the largest molluscs native to the Caribbean Sea, and tropical northwestern Atlantic, from Bermuda to Brazil, reaching up to 35.2 centimetres (13.9 in) in shell length. A. gigas is closely related to the goliath conch, Lobatus goliath, a species endemic to Brazil, as well as the rooster conch, Aliger gallus.
