Acanthurus xanthopterus | M

Acanthurus xanthopterus, commonly known as the Yellowfin Surgeonfish, is a medium-sized tang prized for its vivid yellow pectoral fins and streamlined body. This species is a robust swimmer and can add dynamic movement and colour to a large marine aquarium.

Care Level: Moderate to advanced. This species requires stable water conditions and ample swimming space.

Temperament: Semi-aggressive. It can be territorial towards other tangs, especially in confined spaces, so careful consideration of tank mates is essential.

Diet: Omnivorous. A varied diet including marine algae, seaweed sheets, and high-quality meaty foods such as mysis shrimp and brine shrimp is recommended to maintain optimal health and vibrant colouration.

Minimum Tank Size: At least 250 litres (approximately 65 gallons) to accommodate its active swimming behaviour and territorial nature.

Reef Compatibility: With Caution. While generally reef safe, it may nip at certain sessile invertebrates or corals, so monitoring is advised.

Lighting and Water Flow: Standard marine aquarium lighting is suitable. Moderate to strong water flow mimics its natural reef environment and supports its health.

Placement: Provide plenty of open swimming space along with live rock for grazing and shelter. Avoid overcrowding to reduce stress and aggression.

Origin: Indo-Pacific region.

Maximum Size: Up to 50 cm (20 inches) in length in captivity.

Overall, the Yellowfin Surgeonfish is a captivating addition to a large, well-established marine aquarium, best suited for aquarists with experience in maintaining tang species.
