The fish has a greyish-blue coloration with a pattern of vertical black stripes on the body, which can become more pronounced as the fish matures. The Grey Angelfish has a large dorsal fin and long pectoral fins that are used for propulsion and maneuvering in the water.


The Grey Angelfish is an active and curious fish that enjoys exploring its surroundings. It is not a particularly aggressive fish, but it can become territorial and defend its space if threatened or if other fish encroach on its territory. In the wild, Grey Angelfish can be found swimming in small groups, but in the aquarium, they are best kept as solitary fish or in pairs.

Care Requirements:

The Grey Angelfish is relatively easy to care for and is a good choice for intermediate-level aquarists. They require a minimum tank size of 75 gallons, with plenty of live rock and hiding places to provide shelter and security. The aquarium should be well-filtered and maintained at a stable temperature between 72 and 78 degrees Fahrenheit. The Grey Angelfish is an omnivore and will eat a varied diet consisting of high-quality flake and pellet foods, as well as frozen and live foods such as brine shrimp, krill, and mysis shrimp.


Breeding Grey Angelfish in captivity is challenging, but not impossible. They are known to spawn in pairs, laying their eggs on the underside of rocks or other structures in the aquarium. The eggs hatch after several days, and the fry can be fed on a diet of plankton and small zooplankton until they are large enough to consume regular food.

Potential Health Issues:

The Grey Angelfish is generally hardy and disease-resistant, but it can be susceptible to common aquarium diseases such as ich, velvet, and bacterial infections. It is important to maintain good water quality and provide a varied, balanced diet to keep your Grey Angelfish healthy and thriving.

In the wild, their diet may consist of a variety of algae, sponges, tunicates, and small invertebrates such as worms and crustaceans. In captivity, they can be fed a varied diet consisting of high-quality flake and pellet foods, as well as frozen and live foods such as brine shrimp, krill, and mysis shrimp. It is important to provide a balanced and varied diet to meet their nutritional needs and keep them healthy.

Where are Grey Angelfish commonly found in the wild?

Are Grey Angelfish aggressive towards other fish in the tank?

Grey Angelfish can be aggressive towards other fish in the tank, particularly towards other angelfish or fish of a similar size and shape. They may also become territorial and aggressive towards new additions to the tank. It is generally recommended to keep them with other non-aggressive fish in a larger tank to provide enough space and reduce the chances of aggression. It is important to carefully research and plan the selection of tank mates to avoid compatibility issues.
