Pomacanthus asfur, the Arabian angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It is found in the Western Indian Ocean. Pomacanthus asfur has a completely different colour and pattern as a juvenile from that of the adult. Juveniles have a blue body which is marked with pale-blue and white stripes. As they mature they develop yellow markings on their dorsal and caudal fins. Until as fully mature adults they have an overall dark blue body with a blackish face, a yellow caudal fin and a broad crescent-shaped yellow band running vertically across the flanks. The dorsal fin has 12 spines and 19–20 soft rays while the anal fin has 3 spines and 19–20 soft rays, the pectoral fins each contain 17 or 18 rays. This species attains a maximum total length of 40 cm (16 in). Pomacanthus asfur is principally found in the western Indian Ocean. Here it is found in the Red Sea and the Gulf of Aden and along the coast of eastern Africa as far south as Zanzibar. It has been recorded, as a probable release of aquarium specimens, on a few occasions off the eastern coast of Florida and from Malta.
