Common name: Resplendent Angelfish

General Information

The Resplendent Angelfish, scientifically known as Centropyge resplendens, is a stunning and rare gem in the marine aquarium trade. With its vibrant blue body and striking yellow-orange accents, this diminutive angelfish captivates aquarists with its beauty and elegance. Discovered in the waters surrounding Ascension Island, it has a limited natural range, contributing to its rarity and desirability among hobbyists.

Despite its captivating appearance, the Resplendent Angelfish is not commonly found in home aquariums due to its limited distribution and collection challenges. This species is often sought after by experienced aquarists and collectors who appreciate its unique coloration and the prestige of owning such a rare fish.

Care

The Resplendent Angelfish requires a well-maintained aquarium with plenty of live rock for grazing and hiding. It thrives in environments that mimic its natural habitat, which includes rocky substrates and abundant crevices. As a relatively hardy species, it can adapt to various tank conditions, but stable water quality and parameters are crucial for its well-being.

A tank size of at least 200 liters (approximately 50 gallons) is recommended to provide ample space for swimming and exploring. The aquarium should be equipped with efficient filtration and regular maintenance to ensure optimal water quality.

Diet and Feeding

In the wild, the Resplendent Angelfish is an omnivore, feeding on a diet of algae, small invertebrates, and detritus. In captivity, it should be offered a varied diet that includes high-quality marine angelfish pellets, frozen mysis shrimp, and spirulina-enriched foods. Occasional offerings of live or frozen brine shrimp and finely chopped seafood can provide additional nutrition.

Feed the Resplendent Angelfish small portions several times a day to mimic its natural grazing behavior. This feeding schedule helps maintain its vibrant coloration and overall health.

Behavior and Compatibility

The Resplendent Angelfish is generally peaceful but can exhibit semi-aggressive behavior, particularly towards other dwarf angelfish or similarly sized tank mates. It is best kept as a single specimen or in a well-planned community tank with non-aggressive species.

Due to its semi-aggressive nature, it may not be suitable for tanks with very timid or delicate species. Providing plenty of hiding spots and territories can help mitigate aggression and promote harmonious interactions.

Reproduction

Breeding the Resplendent Angelfish in captivity is challenging and rarely achieved. Like other dwarf angelfish, it is a protogynous hermaphrodite, meaning individuals can change sex from female to male. Successful breeding requires excellent water quality, ample space, and a compatible pair, often requiring careful observation and selection.

Health and Common Issues

The Resplendent Angelfish is susceptible to common marine diseases such as ich and marine velvet. Maintaining pristine water conditions, a balanced diet, and regular health checks can help prevent these issues. Quarantine new additions to the aquarium to avoid introducing pathogens.

Habitat

Naturally found in the rocky reefs of Ascension Island, the Resplendent Angelfish prefers environments with abundant live rock and crevices for hiding and grazing. It thrives in stable water conditions with moderate flow, replicating the gentle currents of its natural habitat.
