Acanthurus thompsoni, known as Thompson’s Surgeonfish, is a visually captivating tang prized for its vibrant colours and active swimming behaviour. This large specimen is best suited for experienced marine aquarists with ample space.
Care Level: Moderate to advanced care is recommended due to its size and specific dietary needs.
Temperament: Generally semi-aggressive; may show territorial behaviour especially towards conspecifics or similar tang species. Best housed singly or in a very large tank with multiple tangs to reduce aggression.
Diet: Primarily herbivorous. Provide a varied diet rich in marine algae and seaweed, supplemented with high-quality herbivore flakes, pellets, and occasional meaty treats to ensure balanced nutrition.
Minimum Tank Size: A minimum of 250 litres (approximately 65 gallons) is recommended to accommodate its active swimming and territorial nature.
Reef Safety: With Caution. While generally reef safe, it may nip at certain sessile invertebrates or corals, so monitor behaviour closely in reef setups.
Lighting Requirements: Standard marine aquarium lighting is sufficient; no special lighting needs.
Water Flow: Moderate to strong water movement mimics natural habitat conditions and supports health.
Placement: Provide ample open swimming space with plenty of live rock for grazing and hiding spots to reduce stress.
Origin: Not Provided.
Maximum Size: Approximately 30 cm (12 inches) in length.
Regular water quality monitoring and stable parameters are essential for maintaining health. This species benefits from a well-established aquarium with mature biological filtration.
