This extra large specimen is ideal for experienced hobbyists who can provide the space and environment needed for its active nature.
Care Level: Moderate to advanced care is recommended due to their territorial behaviour and activity levels.

Diet: Omnivorous – accepts a varied diet including high-quality marine flakes, pellets, frozen mysis shrimp, brine shrimp, and algae-based foods.
Minimum Tank Size: A minimum of 150 litres is advised to provide ample swimming space and reduce territorial disputes.
Lighting Requirements: Standard marine aquarium lighting is sufficient; no special lighting needed.

Reef Safe: With Caution – may nip at corals or invertebrates, especially if underfed or stressed.
When introducing Abudefduf vaigiensis to your aquarium, ensure a well-established tank with stable water parameters. Regular monitoring of behaviour and tank mate compatibility is essential to maintain harmony.
