The Koran Angelfish, Pomacanthus semicirculatus, has a yellow/green body that fades from light to dark with the lighter areas speckled blue and the darker areas speckled yellow and light blue vertical lines along the eyes and face. Like many large Angelfish their appearance will change dramatically from the juvenile to adult stage. Due to aggression towards other Angelfish they are best kept singly but will do well with other larger fish.

They are not reef safe, as they will nip at soft and stony polyp corals, sessile invertebrates and clam mantles. Diet should include a variety of spirulina, marine algae, high quality angelfish preparations, mysis and brine shrimp, 3 times daily.
