Emperor Angelfish (Pomacanthus imperator)
The Emperor Angelfish is one of the most spectacular and recognizable inhabitants of coral reefs. Its vibrant coloration — striking blue and yellow horizontal stripes with a bold black eye mask — makes it a true showpiece for large marine aquariums. Juveniles display a stunning circular blue-and-white pattern that gradually transforms into the adult’s signature stripes, creating a dynamic visual progression over time.
Native to the Indo-Pacific region, the Emperor Angelfish is an active and moderately aggressive species that requires ample swimming space and well-established live rock for grazing and hiding. It thrives in tanks with pristine water quality and a varied diet of algae, marine-based meaty foods, and sponge preparations to maintain its brilliant colors and overall health.
