Centropyge vrolikii

Datasheet

General Description

The Pearlscale angelfish (Centropyge vrolikii) belongs to the Pomacanthidae family, known for their vibrant colors and striking appearance on the reef. They are popular in aquariums due to their smaller size, typically growing up to about 10 cm, with some individuals reaching 18 cm. These fish are not typically reef-safe, as they may disturb LPS corals, Zoanthus, and clams by going after their mucus. Their diet primarily consists of microalgae and detritus, with some species also consuming green hair algae and Spirulina.

Aquarium Suitability

Considered suitable for aquariums with care, Pearlscale angelfish can be a good addition if precautions are taken. Their demands can vary, with specific food requirements and potential difficulty in acclimatization for larger species. Keeping them well-fed with a primary algae-based diet is crucial for maintaining their health and immunity. It is necessary to provide hiding places, especially when introducing them to a new aquarium.

Care and Hardiness

With an average hardiness level, Pearlscale angelfish thrive in a well-established aquarium with ample algae for grazing. Maintaining high water quality with parameters like a temperature of 22.2-25.6°C, pH of 8.1-8.4, and specific gravity of 1.020-1.025 is vital for their well-being. They can be aggressive towards other fish species, so cautious selection and monitoring are recommended.

Reef Suitability

Reef compatibility with Pearlscale angelfish can be challenging, as they may pose a threat to soft corals and LPS. However, with careful coral selection, it is possible to create a mixed coral aquarium with Angelfish. Certain corals like Hammer corals, Bubble corals, Star polyps, and Disc anemones have a higher chance of coexisting peacefully with these fish.

Aquarium Setup

Setting up an aquarium for Pearlscale angelfish involves providing sufficient space, especially when keeping multiple individuals together. Depending on the size of the fish, tanks ranging from 100 gallons for small individuals to 400 gallons for larger ones are recommended. Offering a variety of hiding places and ensuring rock surfaces contain algae for grazing are essential considerations.

Behaviour

Pearlscale angelfish may exhibit aggression, especially towards conspecifics or similar species. They may also nibble on clams, including Tridacna species. It is advisable to monitor their behavior closely, especially during the introduction of new tank mates or rearrangement of the aquarium environment.

Feeding and Diet

These fish primarily feed on microalgae, detritus, and small crustaceans like krill, mysis, and artemia. Providing a diverse diet that includes algae-rich foods like Spirulina, Nori seaweed, and fresh vegetables is crucial. Regular feeding and supplementation with algae-based foods help support their immune system and overall health.

Dimorphism

Pearlscale angelfish species can change gender from female to male, with females transitioning to males when needed. This natural process of gender change allows for potential captive reproduction in suitable environments.

Habitat and Distribution

The Pearlscale angelfish is found in the Western Pacific, ranging from Christmas Island in the eastern Indian Ocean to locations like Bali, the Marshall Islands, Vanuatu, southern Japan, and Lord Howe Island. Recently, sightings have been recorded in Tonga, expanding their known distribution in the region.
