The Acanthurus xanthopterus, commonly known as the Yellowfin Surgeonfish, is a striking and robust tang species prized by marine aquarists for its vibrant yellow fins and impressive size. This extra large specimen is best suited to experienced hobbyists with spacious aquariums due to its active swimming behaviour and territorial nature.
Care Level: Moderate to advanced. This species requires stable water parameters and a well-established tank.
Temperament: Semi-aggressive. It can be territorial, especially towards other tangs or similar-shaped fish. Careful consideration is needed when selecting tank mates.
Diet: Primarily herbivorous. Provide a varied diet rich in marine algae, seaweed sheets, and high-quality herbivore pellets. Supplement with occasional meaty foods to ensure balanced nutrition.
Minimum Tank Size: Due to its large adult size and active swimming habits, a minimum tank size of 250 litres (approximately 65 gallons) is recommended to provide ample space.
Lighting Requirements: Standard marine aquarium lighting is sufficient. Ensure lighting supports healthy algal growth for grazing.
Water Flow: Moderate to strong water movement mimics natural reef environments and promotes fish health.
Placement: Provide plenty of open swimming space along with hiding spots created by live rock. This helps reduce stress and territorial disputes.
Origin: Indo-Pacific region.
Maximum Size: Up to 50 cm (20 inches) in length.
Reef Safety: With Caution. May nip at coral polyps or clam mantles, so not recommended for delicate reef tanks.
Overall, the Yellowfin Surgeonfish is a stunning addition to large marine aquariums, offering vibrant colour and dynamic behaviour. Proper care and tank conditions are essential to maintain its health and well-being.
