Common name: African Sergeant

Scientific name: Abudefduf hoefleri (Steindachner, 1881)

General Information

The African Sergeant, scientifically known as Abudefduf hoefleri, is a striking species of damselfish that captures the attention of aquarists with its bold black and white stripes. This species is native to the eastern Atlantic Ocean, particularly along the coastlines of West Africa. It is a popular choice among hobbyists due to its vibrant appearance and relatively hardy nature.

While not as commonly seen in the aquarium trade as some of its relatives, the African Sergeant is appreciated for its unique look and energetic behavior. It can add a dynamic presence to marine aquariums, especially those designed to mimic rocky reef environments.

Care

The African Sergeant is moderately easy to care for, making it suitable for aquarists with some experience. It thrives in well-maintained marine aquariums with plenty of swimming space and rock formations that provide hiding spots and territories. A tank size of at least 200 liters is recommended to accommodate their active nature and territorial behavior.

Diet and Feeding

In the wild, the African Sergeant is an omnivore, feeding on a varied diet of algae, plankton, and small invertebrates. In captivity, they should be offered a balanced diet that includes high-quality marine flakes or pellets, supplemented with live or frozen foods such as brine shrimp and mysis shrimp.

Feeding should occur once or twice daily, with portions that can be consumed within a few minutes to prevent overfeeding and maintain water quality.

Behavior and Compatibility

African Sergeants are known for their semi-aggressive temperament, particularly towards conspecifics and similar-sized fish. They are best kept in species-specific tanks or with other robust species that can hold their own.

While they can coexist with a variety of tank mates, caution is advised when introducing them to community tanks. They may exhibit territorial behavior, especially if housed in smaller tanks or when establishing dominance.

Reproduction

Breeding the African Sergeant in captivity can be challenging due to their territorial nature. They exhibit typical damselfish breeding behavior, with males preparing and guarding nests on flat surfaces. After spawning, the male will protect the eggs until they hatch.

Health and Common Issues

African Sergeants are generally hardy but can be susceptible to common marine diseases if water quality is not maintained. Regular tank maintenance and monitoring for signs of stress or illness are essential.

When selecting an African Sergeant, look for active individuals with clear eyes and vibrant coloration. Avoid fish with visible signs of disease or damage.

Habitat

In their natural habitat, African Sergeants are found in rocky reefs and coastal lagoons, often in areas with moderate water flow. They are typically seen at depths ranging from 1 to 15 meters. Replicating these conditions in captivity will help them thrive.
