Koran Angelfish (Pomacanthus semicirculatus)


The Koran Angelfish, otherwise known as the Halfcircled Angelfish or the Semicircular Angelfish, are a type of angelfish that changes color with maturation.


As juveniles, the Koran Angelfish is triangular or pointed at the face but rounded in body like a semicircle. Unlike its adult form, the Koran Angelfish isn’t speckled or spotted with changing body colors from yellow to green. The juvenile Koran Angelfish is black with rounded bright blue and white alternating stripes. One of the main similarities between the juvenile and the adult Koran Angelfish is the blue trim that lines the edges of the elongated dorsal and anal fins of these angelfish.


The best housing environment for the Koran Angelfish would be a 250 gallon tank or larger with plenty of live rock for grazing and hiding. These angelfish are not the best reef dwellers and are prone to nipping at soft and stony corals (sessile invertebrates) and clam mantles.



The diet of the Koran Angelfish should include: high-quality angelfish preparations, marine algae, spirulina, mysis, and frozen shrimp. They should be fed at least three times a day
