Common name: Cherub Angelfish

General Information

The Cherub Angelfish, scientifically known as Centropyge argi, is a charming and vibrant species popular among marine aquarium enthusiasts. Known for its striking blue body and yellow face, this small angelfish adds a splash of color to any tank. Its manageable size and relatively hardy nature make it a favorite among both beginner and experienced aquarists.

Hailing from the Caribbean Sea and the Gulf of Mexico, the Cherub Angelfish is often found darting among coral reefs, where it plays a role in controlling algae growth. This species is sometimes confused with the Centropyge acanthops, but the Cherub Angelfish can be distinguished by its more compact body shape and the distinct coloration of its face.

Care

Cherub Angelfish are relatively easy to care for, making them a suitable choice for aquarists with some experience. They thrive in well-established aquariums with plenty of live rock, which provides hiding spots and grazing surfaces. A tank of at least 100 liters is recommended to accommodate their active swimming habits and territorial nature.

Maintaining stable water parameters is crucial for the health of Cherub Angelfish. Regular water changes and efficient filtration help keep the environment clean and healthy.

Diet and Feeding

In the wild, Cherub Angelfish are omnivorous, feeding on algae, small invertebrates, and detritus. In captivity, they should be offered a varied diet to ensure proper nutrition. High-quality marine angelfish pellets or flakes, supplemented with frozen foods like brine shrimp and mysis shrimp, are ideal.

Feed them small amounts multiple times a day, as they are active grazers. Ensuring a diet rich in marine-based algae will help maintain their vibrant coloration and overall health.

Behavior and Compatibility

Cherub Angelfish are known for their semi-aggressive temperament, particularly towards other dwarf angelfish. They are best kept singly or in pairs in larger tanks to minimize territorial disputes. Despite their feisty nature, they can coexist with a variety of other peaceful marine species if introduced properly.

These angelfish are not considered reef-safe, as they may nip at coral polyps and other sessile invertebrates. Caution is advised if adding them to a reef tank, and they should be monitored closely for any destructive behavior.

Health and Common Issues

Cherub Angelfish are generally hardy, but like all marine species, they can be susceptible to common ailments such as ich and marine velvet. Ensuring a stress-free environment and maintaining optimal water quality are key to preventing disease.

When selecting a Cherub Angelfish, look for individuals with bright colors and clear eyes. Avoid fish that show signs of stress or illness, such as clamped fins or labored breathing.

Habitat

The natural habitat of the Cherub Angelfish includes coral reefs and rocky outcrops in the Caribbean. They prefer areas with ample hiding spots and a rich supply of algae to graze on. Replicating these conditions in captivity will help them thrive.
