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.
(A) Alert - This fish cannot be kept with other Angelfish. If you're attempting to purchase two or more Angelfish for the same aquarium it will cause them to fight and most likely one will not survive, so if you're placing an order that has 2 or more Angelfish in it we will have to place the order on hold until we're able to contact you to ensure you're not putting them into the same tank. If you understand they cannot be kept together, but would like to purchase two or more in the same order(separate tanks, group order, etc.) you will need to write in the Special Instructions area at the end of the shopping cart that you understand they cannot be kept together. Tremendous time and effort is put into ensuring the health of these fish and it is very important that you're fully aware two Angelfish should not be kept in the same tank.The Semicirculatus Angel, often referred to as the Blue Koran Angel, is a beautiful juvenile phase fish, which is very similar in markings to that of the Juvi Emperor Angel. The Semicirculatus is a dark blue with narrow white and blue semicircular bands running along its body, becoming more arched towards the rear. The pattern will begin to dissolve into that of the adult at approximately 4 inches. These fish do fairly well in aquariums and prefer lots of rockwork to feel comfortable. The Semicirculatus Angel should be kept in a tank of 100 gallons or larger, so it'll have ample room to roam. They will spend most of their day grazing algae that grows on live rock. They should not be kept with other Angels and only one should be kept per tank.The Angelfish family is a group of colorful and elegant fish that are adored by both the serious and casual observer. These fish are mainly available to the hobbyist under the Genus Pomacanthus and Centropyge. Pomacanthus Angels are the larger more robust species. The Centropyge Genus are made up of smaller fish that feed primarily on algae from the reef surface. The adult Pomacanthus Angels usually have long dorsal and anal fins and a rounded face. The Pomacanthus Angels will change color quite dramatically from their juvenile stage to adult stage. The Centropyge Angels are found predominantly in the Indo-Pacific while only a couple of species, like the Pygmy and Flameback Angels, are found in the Atlantic and Caribbean. At the same time, the Pomacanthus Angels dominate the Atlantic and Caribbean while in the Indo-Pacific they are less prominent. The Centropyge Angels do not change color dramatically from their juvenile stage to adult stage. These smaller Angels are often seen milling around reefs which they use for both shelter and as a food source. Angelfish are differentiated from Butterflyfish by the small spine that extends from the bottom of their rear gill cover.
