Description

Sergeant Major Damselfish: A Bold Striped Addition to Your Marine Aquarium

Bring the vibrant energy of the Atlantic reef to your home with the hardy Sergeant Major Damselfish. Their striking stripes and active nature create an engaging display.

Overview

The Sergeant Major Damselfish (*Abudefduf saxatilis*) is easily recognized by its silvery-white body adorned with five prominent black vertical bars, often featuring a yellowish hue along its back. These active swimmers, named for their military-like markings, patrol the mid-level of your aquarium with confident, schooling behavior when young. As they mature, their presence becomes more pronounced, adding dynamic visual interest.

Care Level

Considered an easy to moderate species, the Sergeant Major Damselfish is quite hardy but possesses a bold, territorial temperament that requires careful consideration of tank mates. Best kept singly or in a small group introduced simultaneously to a spacious environment, they thrive alongside other robust, fast-moving marine fish, enriching your healthy aquarium fish community.

Tank Essentials

A minimum tank size of 200 litres is recommended for a single specimen, though a larger aquarium of 400-600 litres or more is ideal, especially for a group. Provide plenty of live rock with caves, ledges, and open swimming areas to mimic their natural reef habitat. Maintain stable marine parameters: 22-28°C temperature, pH 8.0-8.4, and salinity 1.020-1.026.

Diet

As omnivores, Sergeant Major Damselfish enjoy a varied diet of algae-based foods, such as spirulina flakes and nori, complemented with protein-rich frozen options like mysis shrimp and brine shrimp. Feed two to three small meals daily to support their active metabolism and vibrant coloration.
