Common name: indo-pacific sergeant

General information

The Indo-Pacific Sergeant, Abudefduf vaigiensis, is a small, robust damselfish known for its distinctive five vertical black bars on a yellowish to bluish-grey background. It is a member of the family Pomacentridae, which includes other popular aquarium species such as clownfish and chromis. These fish are active swimmers and can often be seen in large schools in the wild, especially around coral reefs and rocky outcrops.

Care

Indo-Pacific Sergeants are hardy and adaptable, making them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with plenty of swimming space and rockwork for hiding. While they are generally peaceful, they can become territorial, especially during breeding. A varied diet of meaty foods, algae, and high-quality marine flake or pellet food will keep them healthy and vibrant.

Reproduction

In the wild, Abudefduf vaigiensis forms breeding territories that males aggressively defend. They are oviparous, with the females laying eggs on a flat surface, which the males then fertilize and guard until they hatch. In the aquarium, breeding these fish can be a rewarding challenge, with similar care needed for the eggs and fry as in their natural habitat.

Habitat

The Indo-Pacific Sergeant is found throughout the Indo-Pacific region, from the Red Sea and East Africa to the Line Islands and Tuamotu Archipelago, north to southern Japan, and south to New Caledonia. They are commonly found in shallow waters, often not deeper than 15 meters, where they associate with reef structures that provide both food and shelter.
