General Description: The Koran Angelfish, also referred to as the Semicircular Angelfish or Halfcircled Angelfish, is a hardy large angelfish. It is found in the Indo-West Pacific Ocean ranging from the eastern coast of Africa from the southern Red Sea and coast of Sudan south as far as South Africa. It ranges east across the Indian and Pacific Oceans to Fiji, Tonga and Samoa. It occurs as far north as southern Japan and south to Australia. The body color is a yellowish green that gradually turns darker 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 blue gill margins and eye rings. The fins are also outlined in bright blue. The juvenile is black with white and blue stripes. Adults can reach up to 16 inches in length.
Diet Requirements: In the wild they are found on sheltered coral reefs, where they feed on algae, tunicates and sponges. The aquarium diet should include Spirulina, Chlorella, marine sheet algae, occasional high-quality angelfish preparations with sponge included, and mysis or frozen shrimp. It should be fed at least three times daily to help reproduce natural reef grazing behavior.
Care Requirements: The Koran Angelfish requires a 200 gallon or larger tank as an adult, with an 18+ inch width and include large amounts of live rock for hiding and grazing. It does well with other larger active semi-aggressive fish species. Not a good candidate for a reef tank, the Koran Angelfish has a tendency to nip at soft and stony coral polyps and clams. Recommended water conditions, 72-78° F, KH 8-12, pH 8.1-8.4, salinity 1.020-1.025.
