Emperor Angelfish (Pomacanthus imperator)
Scientific Name: Pomacanthus imperator
About the Emperor Angelfish
Species Type: Saltwater Fish
Category: Large Angelfish
Care Level: Difficult. Healthy specimens may be difficult to find, as stress during shipping is normal. Triggering a feeding response in captivity may present a challenge, or meeting the dietary demands of the species may require special daily care. Is prone to disease, requiring high water quality. Proper acclimation and quarantine are essential, and the use of a UV Sterilizer is suggested. Recommended for advanced marine hobbyists only.
Origin: Coral Sea, Indo-Pacific
Compatibility/Temperament: This species mixes well with most other fish, provided other large angelfish are not kept in the same aquarium.
The adult Emperor Angelfish, has a bold, blue body covered with bright yellow horizontal stripes culminating in a bright yellow to orange caudal fin. A blue-black mask covers the eyes and a similarly-colored vertical band extends from the pectoral fin two-thirds of the way up the body. This band is highlighted in a sapphire-blue in front, and bright yellow, caudally. The mouth is white.
The juvenile is black with circular white and blue stripes starting at the tail. Although sought after for its colors, in captivity, the adult coloration may not be as striking or brilliant, and the color transition from juvenile to adult, may not be complete. Supplementing the diet with vitamins and color-enhancing foods may help.
The Emperor Angelfish requires a large tank with live rock for grazing and hiding. It will nip at stony and soft corals and clam mantles, but may be kept with small-polyped stony corals and somewhat noxious soft corals
Emperor Angelfish Diet
It should be fed a diet of Spirulina, marine algae, high-quality angelfish preparations, mysid or frozen shrimp, and other meaty items.
This species grows large, well over 12 inches in length.
Minimum Tank Suggestion
Ideal water parameters for Emperor Angelfish
Marine fish are highly sensitive animals with very specific care requirements. Most all saltwater species will require similar water conditions, designed to replicate that of natural seawater. Ammonia and nitrite levels should absolute zero, temperature at 76F to 80F, and salinity at 1.024 to 1.026. Although some fish are tolerant of lower levels of Nitrate, the goal in every aquariums should be to keep Nitrate as close to zero as possible, and certainly under 20ppm. Finally, maintaining a stable pH of 8.0 to 8.4 is desired. Achieving this is made easier by monitoring alkalinity, which should be kept at 8-12 DKH, and calcium, which is targeted at 400 to 460ppm.
