Common name: Guinean Angelfish

General Information

The Guinean Angelfish, scientifically known as Holacanthus africanus, is a striking marine fish admired for its vibrant coloration and elegance. This species is native to the tropical waters of the eastern Atlantic Ocean, particularly around the islands of the Gulf of Guinea. Its vivid blue and yellow coloration as a juvenile, combined with its graceful swimming patterns, make it a popular choice among advanced marine aquarists.

Despite its beauty, the Guinean Angelfish is not as commonly found in the aquarium trade as some of its relatives, primarily due to its specific care requirements and the challenges associated with its collection and transportation.

Care

The Guinean Angelfish requires a spacious aquarium with plenty of live rock for grazing and hiding. It thrives in well-established tanks with stable water conditions. This species is best suited for experienced aquarists due to its specific dietary needs and sensitivity to water quality changes. A tank of at least 500 liters is recommended to accommodate its active swimming behavior and territorial nature.

Diet and Feeding

In the wild, the Guinean Angelfish is an omnivore, feeding on a variety of sponges, algae, and small invertebrates. In captivity, it requires a varied diet that includes high-quality marine angelfish preparations, spirulina, mysis shrimp, and other meaty foods. Regular feeding and dietary variety are crucial to maintaining its vibrant colors and overall health.

Behavior and Compatibility

The Guinean Angelfish is known for its semi-aggressive temperament. It can be territorial, especially towards other angelfish or similar-looking species. It is best kept as the only angelfish in the tank unless the aquarium is large enough to accommodate multiple territories. This species can coexist with other non-aggressive fish and invertebrates, provided there is ample space and hiding spots.

Health and Common Issues

The Guinean Angelfish can live up to 15 years in captivity with proper care. It is susceptible to common marine diseases such as ich and marine velvet, so maintaining optimal water quality and a stress-free environment is essential. Regular monitoring and quarantine of new tank additions can help prevent the introduction of diseases.

Habitat

This species is found in the rocky and coral-rich areas of the eastern Atlantic Ocean, particularly around the Gulf of Guinea. It prefers warm, clear waters with abundant coral and rock formations, which provide both food and shelter.
