Acanthurus bariene | M

The Acanthurus bariene, commonly known as the Bariene Surgeonfish, is a visually impressive member of the tang family prized for its vibrant blue and yellow markings. This medium-sized tang is a lively and active swimmer, making it a captivating addition to a suitably large marine aquarium.

Care Level: Moderate to advanced. This species requires stable water conditions and a well-established tank.

Temperament: Generally semi-aggressive. It can be territorial, especially towards other tangs or similar-shaped fish, so careful consideration is needed when selecting tank mates.

Diet: Primarily herbivorous. Feed a varied diet rich in marine algae, seaweed sheets (nori), and high-quality herbivore pellets or flakes. Occasional meaty foods can be offered to supplement nutrition.

Minimum Tank Size: At least 180 litres (approximately 50 gallons) to provide ample swimming space and reduce territorial behaviour.

Reef Compatibility: With caution. While generally reef safe, it may nip at certain sessile invertebrates or corals, so monitor behaviour closely.

Lighting and Water Flow: Standard marine aquarium lighting and moderate to strong water flow to mimic natural reef environments.

Placement: Provide plenty of live rock for grazing and hiding spots to reduce stress.

Origin: Indo-Pacific region.

Maximum Size: Up to 30 cm (12 inches) in length.

Overall, the Bariene Surgeonfish is a stunning and rewarding species for marine aquarists prepared to meet its care requirements and provide a spacious environment.
