Common name: Pearlscale Angelfish

General Information

The Pearlscale Angelfish, scientifically known as Centropyge vrolikii, is a captivating species that has gained popularity among aquarium enthusiasts. Known for its striking appearance, this angelfish features a pearlescent body with a gradient of colors ranging from silver to dark brown, often with a hint of blue around the edges. This species is a member of the dwarf angelfish group, making it a suitable choice for medium-sized aquariums.

In the wild, Centropyge vrolikii is found in the Indo-Pacific region, including the Great Barrier Reef, the Solomon Islands, and the Maldives. Its adaptability and relatively peaceful nature make it a favored choice for both novice and experienced aquarists. However, it's important to note that while it is generally hardy, it requires a well-maintained environment to thrive.

Care

The Pearlscale Angelfish is considered moderately easy to care for, provided its specific needs are met. It thrives in aquariums with plenty of live rock, which offers both grazing opportunities and hiding spots. A tank of at least 200 liters is recommended to accommodate its active swimming habits and territorial nature.

Maintaining stable water conditions is crucial for the health of this species. Regular water changes and monitoring of water parameters will help prevent stress and disease. The Pearlscale Angelfish is known to be a bit of a "rock picker," so providing a mature tank with established algae and microfauna is beneficial.

Diet and Feeding

In its natural habitat, the Pearlscale Angelfish is an omnivore, feeding on algae, small invertebrates, and detritus. In captivity, a varied diet is essential to maintain its health and vibrant coloration. Offer a mix of high-quality marine pellets, frozen foods like brine shrimp and mysis shrimp, and spirulina-based foods.

Feed this angelfish two to three times daily, ensuring that it receives enough nutrition without overfeeding. Observing its feeding habits can help adjust portions and prevent waste buildup in the tank.

Behavior and Compatibility

The Pearlscale Angelfish is generally peaceful but can exhibit semi-aggressive behavior, especially towards other dwarf angelfish. It's best kept singly or as a mated pair unless housed in a large aquarium with plenty of hiding spots. This species can coexist with a variety of reef-safe fish and invertebrates, though caution is advised with small ornamental shrimp.

Health and Common Issues

The Pearlscale Angelfish can live up to 5-7 years in captivity with proper care. Selecting a healthy specimen involves looking for clear eyes, intact fins, and active swimming behavior. Regular tank maintenance and a balanced diet are key to preventing common health issues such as marine ich and fin rot.

Habitat

In the wild, Centropyge vrolikii inhabits coral-rich lagoons and outer reef slopes, often found at depths ranging from 5 to 30 meters. It prefers environments with abundant coral and rock formations, which provide both food and shelter. In captivity, replicating these conditions with live rock and coral structures will help the angelfish feel secure and exhibit natural behaviors.
