Emperor Angelfish

Scientific Name: Pomacanthus imperator

The Emperor (Imperator) Angelfish has bold yellow and blue horizontal stripes, a black mask, and a yellow tail as an adult.

Why We're Obsessed

The Emperor is one of the most iconic angels in the world. A big adult is pure display-tank royalty.

Care: Reef safe with caution (likely to nip LPS, softies, and clams). Semi-aggressive toward other angels. Feed sponge-based foods, mysis, and seaweed. Max size about 15". Minimum tank size: 180 gallons.
