Common name: Flameback Angelfish

General Information

The Flameback Angelfish, scientifically known as Centropyge aurantonotus, is a stunning dwarf angelfish species that captivates aquarists with its vibrant colors and lively personality. Native to the western Atlantic, particularly around the Caribbean and the coast of Brazil, this species is a popular choice for both beginner and experienced saltwater aquarium enthusiasts.

Characterized by its deep blue body and contrasting brilliant orange-yellow back and dorsal fin, the Flameback Angelfish is a true visual delight. Its small size and relatively hardy nature make it an appealing addition to many home aquariums. While it shares similarities with the Centropyge acanthops, Centropyge aurantonotus is distinguished by its blue tail and somewhat more peaceful temperament.

Care

Flameback Angelfish thrive in well-maintained aquariums that mimic their natural reef habitats. They require a tank with plenty of live rock, which provides both grazing opportunities and hiding spots. A minimum tank size of 200 liters (about 50 gallons) is recommended to accommodate their active swimming behavior and territorial nature.

These angelfish enjoy a diet that includes a variety of foods. Offer a mix of marine algae, high-quality angelfish pellets, and frozen foods like mysis shrimp and brine shrimp. Regular feeding with a balanced diet will ensure their vibrant colors and overall health.

Diet and Feeding

In the wild, the Flameback Angelfish is an omnivore, feeding on algae, small invertebrates, and detritus. In captivity, they should be offered a varied diet to meet their nutritional needs. High-quality pellets or flakes designed for marine fish, along with frozen or live foods, are ideal.

Feed them once or twice daily, providing only what they can consume in a few minutes to prevent overfeeding and maintain water quality. A varied diet will help prevent nutritional deficiencies and keep them active and healthy.

Behavior and Compatibility

Flameback Angelfish are known for their semi-aggressive temperament, which can manifest as territorial behavior, especially in smaller tanks or when housed with similar-looking species. They are best kept singly or in a well-established community tank with other peaceful fish.

While they are generally reef-safe, caution is advised as they may nip at coral polyps or clams, particularly if not well-fed. Providing ample space and a diverse diet can help mitigate these behaviors.

Reproduction

Breeding Flameback Angelfish in captivity is challenging but not impossible. They are protogynous hermaphrodites, meaning individuals can change sex from female to male. Successful breeding requires a stable environment and a compatible pair, typically established by introducing a group of juveniles and allowing them to form a pair naturally.

Spawning usually occurs at dusk, with the female releasing eggs that are fertilized by the male. The eggs are pelagic, floating in the water column until they hatch. Raising the fry requires a separate rearing tank and a diet of microscopic plankton.

Health and Common Issues

Flameback Angelfish can live up to 5-7 years in captivity with proper care. Regular monitoring of water quality and maintaining a stable environment are crucial for their health. Look for active, brightly colored individuals when purchasing.

Common health issues include marine ich and fin rot, often due to stress or poor water conditions. Quarantine new fish and maintain high water quality to prevent disease. Supplementing their diet with vitamins can support their immune system and enhance their coloration.

Habitat

The natural habitat of the Flameback Angelfish includes coral reefs and rocky outcrops at depths ranging from 5 to 40 meters (16 to 131 feet). They are typically found in the western Atlantic, from the Caribbean to the coast of Brazil. These environments provide ample hiding spots and grazing opportunities, which are essential for their well-being in captivity.
