The Koran Angelfish (Pomacanthus semicirculatus) is also sometimes called the Semicircle Angelfish (from the scientific name) and is one of the better suited marine angelfish for hobbyists because it adapts well to aquarium life. They are often kept in community type FOWLR setups but can become territorial as they mature.

They will eat most foods given but need a staple diet heavy in algae based foods, also known as nori. Live rock can provide feeding opportunities in between meals. Mysis shrimp, brine shrimp, clams on the half shell, etc. will be accepted as well. Feed them several times a day for best results.

The Koran Angelfish is being sold for around $40 to $100 depending on size. It is also interesting to note that juvenile colors are very different from the adults.

The angelfish in Pomacanthus spp. are (generally speaking) less aggressive than the angelfish from Holacanthus spp. but use caution when stocking. It's best to keep annularis angelfish in large fish only type setups. The Blue Ring Angelfish needs lots of open swimming space and needs to be fed often.

This is one of the most expensive saltwater angelfishes to buy. Juveniles look very different than the adults and these Angels need a very high quality diet. They eat lots of sponge in the ocean.
