Kingdom: Animalia
Phylum: Chordata
Class : Actinopterygii (ray-finned fishes)
Order: Pectiformes (Perch-likes)
Family : Pomacanthidae (Angelfishes)

Genus/species: Centropyge argi

GENERAL CHARACTERISTICS: Like their close relatives the butterflyfishes, they have a deep, laterally compressed body, a single, unnotched dorsal fin, and a small mouth with brushlike teeth. The most observable difference between the two families is the long spine at the corner of the preopercle common to angelfishes.

C. argi is a small, oval angelfish. The body is dark blue with a yellow-orange face and blue ring around the eye. Pectoral fins are pale yellowish; other fins deep blue with pale blue margins.
Length up to 8 cm (3.1 in)



DISTRIBUTION/ HABITAT: Bermuda, Florida, Bahamas, Yucatan and Central American coast to Guianas. Nocturnally active in pairs or small groups in rubble areas near rocky or coral reefs, occasionally walls. 

Depth 9–105 m (30-345 ft), commonly deeper than 30 m (100 ft)

DIET IN THE WILD: Omnivorous, feeds on algae, benthic inverts and detritus.

REPRODUCTION/DEVELOPMENT: Broadcast spawners. All Centropyge are born female. As they grow, the larger and more dominant fish will become male and the others will remain female. If the male dies, the next in command in the hierarchy will turn to male.

PREDATORS: Preyed on by other fish such as yellow-finned tunafish. This small angelfsh darts into crevices when frightened or pursued by predators.

Lifespan: Have been reported to live up to 5 years in captivity.
