The Acanthurus lineatus, commonly known as the Lined Surgeonfish, is a visually captivating species prized for its bold blue and yellow horizontal stripes and dynamic swimming behaviour. This large tang is a popular choice among experienced marine aquarium enthusiasts seeking a vibrant and active addition to their reef or fish-only setups.
Care Level: Moderate to Advanced. Due to its size and specific dietary needs, it is recommended for aquarists with some marine fish experience.
Temperament: Semi-aggressive. While generally peaceful towards other species, it can be territorial towards conspecifics and similar tangs, especially in smaller tanks.
Diet: Herbivorous. The Lined Surgeonfish requires a diet rich in marine algae and seaweed. Supplement with high-quality dried seaweed sheets, spirulina, and vegetable-based pellets to maintain optimal health and vibrant colouration.
Minimum Tank Size: 180 litres (approximately 50 gallons). A large, well-established aquarium with ample swimming space is essential to accommodate its active nature and reduce territorial behaviour.
Reef Compatibility: With Caution. While generally reef safe, it may nip at certain sessile invertebrates or corals, so monitoring is advised.
Lighting Requirements: Standard marine aquarium lighting is sufficient. No special lighting needs beyond what supports a healthy reef environment.
Water Flow: Moderate to strong water movement mimics its natural reef habitat and supports its health.
Placement: Mid to upper levels of the aquarium where it can swim freely and graze on algae.
Origin: Indo-Pacific region.
Maximum Size: Up to 30 cm (12 inches) in length.
Providing a varied herbivorous diet and maintaining pristine water conditions will help ensure the longevity and vibrancy of your Acanthurus lineatus. Regular tank maintenance and careful selection of tank mates will minimise stress and aggression.
