Common name: emperor angelfish

General information

The Emperor Angelfish, Pomacanthus imperator, is a vibrant and striking species popular among aquarists for its dynamic coloration and patterns. Juveniles display a dark blue body with electric blue and white rings; as they mature, their coloration transitions to a bright yellow and blue with black stripes, which can make them a centerpiece in any marine aquarium.

This species is known for its adaptability and can often be seen grazing on algae in the wild. It's important to note that while they are hardy, they require a large and well-maintained aquarium to thrive due to their size and activity level.

Care

Emperor Angelfish require a spacious tank with plenty of room to swim and stable water conditions. They are not the easiest fish to keep due to their size and dietary needs. A varied diet of marine algae, spirulina, mysis shrimp, and other high-quality prepared foods is essential for their health and coloration.

They can be territorial, especially towards other angelfish, so careful consideration should be given when adding tank mates. Providing plenty of hiding places and live rock for grazing will help mimic their natural environment and reduce stress.

Reproduction

In the wild, Emperor Angelfish are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Breeding them in captivity is challenging and rarely successful due to the large space and specific conditions required for spawning.

Habitat

Emperor Angelfish are found in the Indo-Pacific region, from the Red Sea to Hawaii and the Austral Islands. They prefer reef environments, often seen in lagoons and outer reefs where they have access to plenty of live rock and coral for grazing and shelter. They can be found at depths ranging from 1 to 100 meters.
