Product Description
The juvenile Koran Angelfish (Pomacanthus semicirculatus) (approximately 8cm) is a striking marine species prized for its dramatic blue and white concentric pattern that gradually transitions into a bold adult coloration of blue-green with yellow scale accents. This impressive transformation makes it a highly sought-after centrepiece fish in large marine aquariums.
Best suited to experienced aquarists, the Koran Angelfish thrives in mature saltwater systems with stable water parameters and abundant live rock for grazing and shelter. It is active, intelligent, and develops a strong personality as it matures.
