Native to the Indo-West Pacific, including parts of Australia, Indonesia, the Red Sea and the wider Indo-Pacific, this species inhabits coastal reefs, lagoons and rocky environments where it grazes on sponges, tunicates and algae.\u003c\/p\u003e\n\u003cp\u003eOne of the most fascinating features of the Koran Angel is its dramatic colour transformation throughout its life. Juveniles display a striking dark blue to almost black body covered in beautiful curved white and electric-blue semicircular stripes. As the fish matures, these markings gradually disappear, developing into an attractive greenish-yellow and brown body covered in small blue spots, with vivid blue edging around the fins and distinctive elongated dorsal and anal fin extensions.\u003c\/p\u003e\n\u003cp\u003eKoran Angels are active, confident swimmers that spend much of their time exploring rockwork, grazing on surfaces and investigating their surroundings. Juveniles can initially be relatively shy, particularly when introduced to a new aquarium, but adults generally become much bolder and can develop territorial behaviour as they mature.\u003c\/p\u003e\n\u003cp\u003eAquarium Suitability and Compatibility\u003c\/p\u003e\n\u003cp\u003eThe Koran Angel is best suited to large, established fish-only-with-live-rock (FOWLR) aquariums. With an adult size reaching approximately 40 cm, this species requires considerable swimming space, excellent filtration and plenty of mature live rock.\u003c\/p\u003e\n\u003cp\u003eAlthough juveniles may initially leave corals alone, Koran Angels should not be considered reef safe. Their natural feeding behaviour involves grazing on sponges and other sessile invertebrates, and they may nip at soft corals, LPS corals, SPS corals, zoanthids and clam mantles. They are therefore unsuitable for aquariums containing valuable corals or delicate invertebrates.\u003c\/p\u003e\n\u003cp\u003eTheir temperament is generally semi-aggressive, with territorial behaviour becoming more pronounced as they grow. They are best housed with other robust marine fish of compatible size, such as larger tangs, rabbitfish, wrasses and selected triggerfish. Avoid keeping them with timid species, small delicate fish or similarly shaped angelfish unless the aquarium is exceptionally large.\u003c\/p\u003e\n\u003cp\u003eFeeding and Nutrition\u003c\/p\u003e\n\u003cp\u003eKoran Angels are omnivores and require a varied, nutritionally balanced diet to maintain their health, growth and colouration.
