Common name: Indo-Pacific Sergeant

General Information

The Indo-Pacific Sergeant, scientifically known as Abudefduf vaigiensis, is a popular species among marine aquarists due to its striking appearance and active behavior. This species is characterized by its bold black vertical stripes against a pale blue to yellowish body, which makes it a visually appealing addition to any aquarium. It is commonly found in the Indo-Pacific region, including the Red Sea and eastern Africa to the central Pacific.

In the aquarium trade, the Indo-Pacific Sergeant is appreciated for its hardiness and adaptability, making it a suitable choice for both novice and experienced hobbyists. Its active swimming patterns and schooling behavior provide dynamic movement in the tank, and it is often used in educational settings to demonstrate marine life behavior and ecology.

Care

The Indo-Pacific Sergeant is relatively easy to care for, thriving in well-maintained aquariums with plenty of swimming space. They prefer environments that mimic their natural reef habitats, with ample rockwork and open water for swimming. While they are adaptable to a range of water conditions, maintaining stable parameters is key to their health.

Diet and Feeding

As an omnivore, the Indo-Pacific Sergeant enjoys a varied diet. In the wild, it feeds on algae, small invertebrates, and zooplankton. In captivity, a balanced diet can be achieved with high-quality flake foods, pellets, and occasional treats of frozen or live foods like brine shrimp and mysis shrimp. Regular feeding twice a day is recommended to keep them healthy and vibrant.

Behavior and Compatibility

The Indo-Pacific Sergeant is known for its semi-aggressive temperament. It is best kept in groups to diffuse aggression, but care should be taken when housing with more timid species. They are compatible with other robust fish that can hold their own in a community setting.

Reproduction

Breeding the Indo-Pacific Sergeant in captivity can be challenging due to their specific requirements for spawning. They are egg layers, with males often guarding the eggs until they hatch. Successful breeding typically requires a dedicated setup with optimal conditions to encourage spawning behavior.

Health and Common Issues

The Indo-Pacific Sergeant is generally hardy, but like all marine species, it is susceptible to common ailments such as ich. Maintaining good water quality and a balanced diet can help prevent most health issues. Quarantine new additions to avoid introducing diseases.

Habitat

In the wild, the Indo-Pacific Sergeant inhabits coral reefs and rocky shorelines, often found in large schools. They prefer shallow waters with plenty of sunlight and moderate water movement, which should be replicated in the home aquarium to ensure their well-being.
