Pomacanthus asfur also known as the Arabian angelfish or Cresent Angelfish is a striking fish, juvenile is blue with light-blue and white stripes, it looks similar to the Koran angelfish except the Arabian Angelfish or Cresent Angelfish has 3 bars that are predominantly white. Older juveniles have yellow markings on the dorsal and a yellow caudal fin that make them distinguishable from the Koran angelfish.
The Arabian angelfish is found singly or in pairs in the Red Sea and Gulf of Aden, south to Zanzibar. Also known as the Asfur Angelfish this fish occurs almost in the Red Sea and as a result prefers a higher than normal specific gravity. Generally 1.026 and above will keep this fish happy.
Pomacanthus asfur is one of the least aggressive of the species, will genenrally only bother other Angels, more passive tankmates, and newly introduced fish. It is difficult to keep as it feeds in the wild primarily on sponges, but also tunicates, algae, zooantharians, gorgonians, hydroids, bryozoans, and seagrasses. In captivity it is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles. A mature Arabian angelfish may have grown 35 to 40 centimeters long.
