PHILIPPINE FISHES

Koran Angelfish (Pomacanthus semicirculatus)

The Koran angelfish or semicircle angelfish, Pomacanthus semicirculatus, is a ray-finned fish in the family Pomacanthidae. It is found in the Indo-West Pacific Ocean. It occasionally makes its way into the aquarium trade.

The adult semicircle angelfish is a pale brownish-green color. It is a deep-bodied, laterally compressed fish that can grow to a length of 35 centimeters (14 in). The mouth is positioned just above the tip of the snout, and the eyes are set halfway up a long straight forehead. The scales have blue bases which gives the body a speckled effect. The fins, except for the pectorals, are rimmed in blue and so are the cheek, operculum and spine. The dorsal fin has 13 spines and 20–23 soft rays and the anal fin has 3 spines and 18–22 soft rays. Both these fins have filaments that trail behind as the fish swims. The pectoral fins are pale yellow and have 19–21 soft rays. The juveniles in contrast, are blue-black marked from top to bottom with narrow white stripes. At the head end the stripes are fairly straight but they become increasingly curved as they approach the base of the tail. The juveniles gradually adopt the adult coloration when they are 8 to 16 centimeters (3.1 to 6.3 in).
