Pomacanthus arcuatus
The gray angelfish has a thin, discus-shaped body with a small mouth. The lower jaw protrudes past the upper jaw. The mouth is small and contains comb-like teeth. All vertical fins are scaled and the dorsal fin is continuous, helping to distinguish it from the closely related spadefish which has two separate dorsal fins. The anal and dorsal fins both have filaments that may stretch past the end of the caudal fin. The pectoral fin extends past the base of the anal fin. The caudal fin is rounded in juveniles while the adults have a nearly straight edge.

Usually observed in pairs, the gray angelfish swims among coral reefs at depths ranging from 7-98 feet (2-30 m). Reef habitats provide plenty of cover for the angelfish to hide from predators during night time hours.
