Koran Angel – Pomacanthus semicirculatus – Medium Juvenile

The Koran Angel (Pomacanthus semicirculatus, also called the Semicircle Angel) is a common angel available in the aquarium trade. Juvenile Koran Angels have a black body with narrow blue and white markings that arch toward the rear of the body. There is a distinct white half circle marking near the tail. It is most similar in appearance to the Emperor Angel (P. imperator) but the white circles in the Koran Angel do not form the complete circles seen in the juvenile Emperor Angel. The adult Koran Angel has a greenish-brown body. A wide, lightly colored vertical band with blue spots covers its sides, and a blue outline adorns the gill cover and fins.

The larger angelfish available in the aquarium trade include those from the genera Apolemichthys, Chaetodontoplus, Holacanthus, Pomacanthus, and Pygoplites. Of these, Apolemichthys and Chaetodontoplus are generally the smallest and are sometimes considered \
