Blue Koran Angelfish: The Transformative & Regal Showpiece

The Blue Koran Angelfish (Pomacanthus semicirculatus), also known as the Semicircle Angelfish, is a magnificent and bold fish that serves as a stunning centerpiece in a large marine aquarium. This angelfish is famous for its dramatic transformation from a juvenile to an adult. Juveniles are a beautiful dark blue with concentric white semicircular stripes, while adults develop a greenish-brown body covered in small blue spots. It is an active and graceful swimmer that requires plenty of open space to roam. While its beauty is undeniable, it is a territorial fish and can be aggressive towards other angelfish and some other tank mates. It is considered reef-safe with caution, meaning it may occasionally nip at soft corals or clams.

• Dramatic Transformation: Its stunning color change from juvenile to adult makes it a fascinating addition to any tank.
