The Koran Angelfish (Pomacanthus Semicirculatus), also referred to as the Semicircular Angelfish or Halfcircled Angelfish, is an extremely popular and hardy angelfish.

As an adult, the body color is a yellow-green that bleeds from light to dark moving front to back along the body. Lighter areas are speckled-blue while darker areas have a more yellow-speckled appearance. The head is a plain yellow-green with sapphire-blue gill margins and eye rings. The fins are also outlined in sapphire blue. The juvenile is black with white and blue stripes. Juveniles adapt better to captivity than adults. 

This beautiful specimen is perfect for the fish only aquarium. The Koran Angelfish requires a 250 gallon or larger tank with large amounts of live rock for hiding and grazing upon slime algae and cyanobacteria.

The Koran Angelfish is aggressive towards it own species and towards other angelfish species. It can also be a good idea to choose specimens that are very dissimilar in size and add the smallest ones first. It is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles so it is not a good candidate for a reef aquarium. Juvenile specimens are less risky for a reef aquarium since they primarily feed on algae and tiny animals that live in the algae, but you can never be 100% sure and you must of course take into a account that the fish won’t stay juvenile forever. 

A varied diet of Spirulina, marine algae, high-quality angelfish preparations, and mysis or frozen shrimp should be offered at least three times a day. Since the Koran Angelfish is a grazing species, it should be fed small portions throughout the day instead of just one or two large meals.
