The Asfur Angelfish is also referred to as the Arabian Angelfish, or Crescent Angelfish. Originating in the Red Sea, but also found in the Indo-Pacific, the Asfur has a dark blue/purple body, black face, yellow tail, and a predominant yellow crescent bisecting the body vertically. Often confused with Maculosus Angelfish Pomocanthus maculosus, the Asfur Angelfish has a bright yellow tail. As with some other Pomacanthus, the coloration of the juvenile differs markedly from the adult.
A shy fish that does best when not kept with other Asfurs due to territorial behavior, the Asfur Angel requires a minimum of a 100-gallon tank with numerous hiding places and live rock for grazing. The Asfur Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles, but may be kept with small-polyped stony corals and somewhat noxious soft corals.
All Angelfish are hermaphroditic. The Asfur Angelfish is indistinguishable from male to female and very difficult to breed in an aquarium.
In a restricted reef environment, the Asfur Angelfish requires a diet of vegetables, meats, and high-quality angelfish preparations containing spongiform products.
