The Koran Angelfish requires a 250 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 so it is not a good candidate for a reef aquarium.

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

The Koran Angelfish is also commonly known as Koran Angel, Blue Koran Angel, Semicircle Angel, Half-circle Angel. The juvenile Koran Angel fish has a bluish-black body blended with concentric semi-circles whereas in adult fish it exhibits brownish on the anterior and posterior third of the body, while the middle part of the body is greenish or yellowish along with abundance of spots on its sides. As the Koran Angelfish fish grows, the semicircles develop into sweeping lines. The water quality should be excellent along with the temperature range of 71-77 degree Fahrenheit, and pH value between 8.1 to 8.4 for the Koran Angelfish to thrive well. Also, it is not advisable to keep adult Koran Angelfish in aquarium smaller than 100 gallon. The presences of a few live rocks are recommended to continue the normal grazing behavior in captivity. Juvenile Koran Angelfish fish is considered less risky for a reef aquarium but as they grow they intend to destroy or nip at stony corals with large polyps and eats clams, soft corals. It is aggressive towards other similar genus species, other angelfish, and its own species, therefore we suggest you to keep them singly or if you still want to keep it in group it is advisable to keep them in a large and cleverly decorated aquarium. The Koran Angelfish is an omnivore and feeds mainly on sponges, tunicates and algae. Also it eats corals, worms, crustaceans and mollusks. Apart from these feeding habits, additional meaty foods such as fresh, frozen shrimps, Mysis shrimps are beneficial for its continued health growth.

Physical description: The juvenile P. semicirculatus is dark blue with light blue and white semi-circles on the body. The tail has white markings with a white margin. Adults are green overall with blue spots on each scale and a blue head. The adult Koran angelfish also has a beautiful filament on the rear edge of the dorsal fin. The transformation from juvenile to adult usually begins when the Koran angelfish is between 3 and 6 inches. The Koran angelfish can reach a maximum length of 14 inches. While an adult Koran angelfish is not likely to be confused with other angelfish, juveniles are similar to those of several other species, including the sixbanded angelfish (P. sexstriatus) and the blueface angelfish (P. xanthometopon).

Range: The Koran angelfish ranges from east Africa east to Fiji. The Koran angelfish is found over a depth range of less than 3 to at least 130 feet near lagoon patch reefs, reef flats, reef faces and slopes. The Koran angelfish tends to occur in coral-rich habitats where it hunts for the sponges and tunicates that make up the majority of its diet. The Koran angelfish tends to be a solitary fish, though it is likely to be a haremic species like its close relatives.

Compatibility: The young Koran angelfish can be a nasty neighbor in a smaller aquarium. Juveniles may not tolerate the presence of other angelfish (particularly if they have a similar color pattern) and will chase and nip at butterflyfish and rabbitfish that are smaller or similar in size. Of course, placid species, such as firefish and dartfish, are also likely targets. If you want to house P. semicirculatus with other angelfish, place the fish in a large aquarium (180 gallon aquarium or larger is optimal) and make sure the species selected are as different in coloration as possible. Also provide plenty of places to hide and select specimens that differ significantly in size (make sure the smaller fish are added before the larger ones). Do not keep two juvenile Koran angelfish in the same aquarium. It is also risky to place adult Koran angelfish together, unless they are housed in a very large aquarium (400 gallons or larger) and the fish are of the opposite sex (the sexes are difficult to tell apart, so it is a matter of trial and error). While the young Koran angelfish may behave itself with sessile invertebrates, an adult may begin nipping at corals in the reef aquarium. The treelike soft corals are most likely to be ignored by large angelfish.

Aquarium conditions: The adult Koran angelfish should be housed in a very large aquarium (at least 135 gallons, preferably more than 200 gallons). The Koran angelfish needs plenty of good hiding places to dart into when frightened, as well as unobstructed swimming room. Keep the water parameters for the Koran angelfish as follows: pH of 8.1 to 8.4, specific gravity of 1.019 to 1.025 and a water temperature of 74 to 82.

Care considerations: The Koran angelfish will do well in the home aquarium if you provide it with enough space and a varied diet (that includes some plant material). As with any potential aggressive marine fish, the more space available, the less likely aggression with be a real problem.

Breeding: The Koran angelfish is not likely to spawn in the home aquarium.
