Common name: Gray Angelfish
General Information
The Gray Angelfish, scientifically known as Pomacanthus arcuatus, is a striking and robust species popular among marine aquarists. Known for its large size and distinctive coloration, this angelfish is a captivating addition to large home aquariums. The Gray Angelfish is easily recognized by its gray body adorned with dark, crescent-shaped bands and a white face, making it a standout in any marine setup.
In the wild, these angelfish are found in the western Atlantic, from Florida and the Bahamas to Brazil, often inhabiting coral reefs and rocky outcrops. They are important members of the reef community, contributing to the control of sponge populations, which they feed on.

Care
Due to their size and dietary needs, Gray Angelfish require a spacious aquarium, ideally over 500 liters, to accommodate their active swimming habits and territorial nature. A well-established tank with plenty of live rock is essential, as it provides both grazing opportunities and hiding spots. Maintaining stable water conditions with efficient filtration is crucial for their health.
Gray Angelfish are not considered reef-safe, as they tend to nip at corals and sessile invertebrates. Therefore, they are best kept in fish-only or carefully planned FOWLR setups.
Diet and Feeding
In their natural habitat, Gray Angelfish are primarily spongivores, feeding on a variety of sponges and tunicates. In captivity, their diet should be supplemented with high-quality angelfish preparations that include marine algae, spirulina, and mysis shrimp. Offering a varied diet will ensure they receive the necessary nutrients and help maintain their vibrant coloration.
Feed them two to three times daily, providing only as much food as they can consume in a few minutes to prevent overfeeding and maintain water quality.
Behavior and Compatibility
Gray Angelfish are semi-aggressive and can exhibit territorial behavior, especially in smaller tanks. They are best housed with other large, robust fish that can hold their own, such as tangs and larger wrasses. Avoid keeping them with smaller, more timid species that may be bullied.
These angelfish are typically solitary or found in pairs in the wild. In captivity, they can be kept solo or in a pair, provided the tank is large enough to accommodate their space needs.
Reproduction
Breeding Gray Angelfish in captivity is challenging and rarely achieved by hobbyists. In the wild, they are known to form pairs and engage in courtship displays, but replicating these conditions in an aquarium setting is difficult. Successful breeding requires a large, well-maintained tank and a lot of patience.
Health and Common Issues
Gray Angelfish can live up to 15 years in captivity with proper care. They are generally hardy but can be susceptible to common marine diseases such as ich and marine velvet. Maintaining optimal water quality and a balanced diet is key to preventing health issues.
When selecting a Gray Angelfish, look for active individuals with clear eyes and smooth, intact fins. Avoid fish that appear lethargic or have visible signs of disease.
Habitat
Gray Angelfish are native to the western Atlantic Ocean, thriving in coral reefs and rocky areas. They prefer warm, tropical waters with plenty of hiding spots and grazing opportunities. In captivity, replicating these conditions with live rock and stable water parameters will help them thrive.
