Koran Angelfish
Veterinary & Aquatic Services Department, Drs. Foster & Smith, Inc.

The Koran Angelfish, 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.

The Koran Angelfish requires a 100 gallon or larger tank with large amounts of live rock for hiding and grazing upon slime algae and cyanobacteria. It is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles, and therefore, is not a good candidate for a reef aquarium.

A varied diet of Spirulina, marine algae, high-quality angelfish preparations, and mysid or frozen shrimp should be offered at least three times a day.
