Acanthurus thompsoni, or Thompson’s Surgeonfish, is a striking tang species native to the Indo-Pacific region. This small-sized tang is known for its vibrant blue and yellow hues and distinctive body shape, making it a popular choice for advanced marine aquarium enthusiasts.
Care Level: Moderate to advanced. This species requires stable water parameters and a well-established aquarium.
Temperament: Semi-aggressive. It can be territorial, especially towards other tangs or similar-shaped fish, so careful consideration of tank mates is essential.
Diet: Primarily herbivorous. Feed a varied diet rich in marine algae, seaweed sheets, and high-quality herbivore pellets or flakes. Supplement with occasional meaty foods to ensure balanced nutrition.
Minimum Tank Size: At least 180 litres (approximately 50 gallons) to provide ample swimming space and reduce territorial behaviour.
Reef Safe: 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 needed.
Water Flow: Moderate to strong water movement mimics natural reef environments and supports fish health.
Placement: Mid to upper water column. Provide plenty of live rock for grazing and hiding spots.
Origin: Indo-Pacific region.
Maximum Size: Up to 25 cm (10 inches) in length.
Ensure regular water changes and maintain excellent water quality to keep Acanthurus thompsoni healthy and vibrant. Avoid housing with overly aggressive species to minimise stress.
