Adult Emperor Angelfish – 3–4.5" (Pomacanthus imperator)
Iconic Color. Commanding Presence. A True Marine Showpiece.
The Emperor Angelfish, also known as the Imperator Angelfish, is one of the most recognizable large marine angelfish in the hobby. Adults develop brilliant yellow and electric-blue horizontal striping, a striking blue-black facial mask, and a commanding presence that makes them an incredible centerpiece for a large saltwater aquarium.
This listing is for an adult-coloration Emperor Angelfish approximately 3–4.5 inches at the time of sale. Individual size, coloration, and pattern may vary naturally.
Care Information
Scientific Name: Pomacanthus imperator
Common Name: Emperor Angelfish / Imperator Angelfish
Purchase Size: Approximately 3–4.5 Inches
Maximum Adult Size: Up to approximately 15 Inches
Care Level: Moderate
Temperament: Semi-Aggressive / Territorial
Diet: Omnivore
Reef Safe: With Caution
Minimum Tank Size: 225 Gallons
Emperor Angels become very large and require substantial swimming room, established rockwork, hiding areas, and excellent water quality. A 225-gallon minimum is a reasonable long-term recommendation for an adult specimen.
Feeding
Offer a varied diet including quality marine angelfish preparations, marine algae and seaweed, spirulina-based foods, mysis shrimp, chopped seafood, and other suitable marine foods.
A diverse diet is particularly important for large marine angelfish, whose natural feeding behavior includes grazing on algae and various encrusting organisms.
Reef Compatibility
Emperor Angelfish should be considered reef safe with caution.
They may nip at or consume certain corals and sessile invertebrates, particularly fleshy LPS, soft corals, and clams. Individual behavior varies, but this species is best suited to large FOWLR systems or carefully planned reef aquariums where the owner accepts the risk of coral predation.
Quarantine & Shipping Preparation
This fish ships through our Chicago livestock facility and may require up to a 14-day quarantine and preparation window before shipment.
The supplier currently states that this fish ships within a 14-day quarantine window, depending on where the individual fish is in the quarantine process when ordered.
Once the fish is ready for shipment, it will be scheduled for an eligible live-animal shipping day.
Useful Pairings
Prepare with our fish acclimation and isolation equipment, species-appropriate fish foods and water testing supplies. Choose food and equipment for the animal’s adult needs. Supplier preparation does not replace your own quarantine.
