The Acanthurus lineatus, or Lined Surgeonfish, is a visually stunning tang distinguished by its bold blue and yellow horizontal stripes. This medium-sized fish is a popular choice among marine aquarium enthusiasts who can provide the space and care it requires.
Care Level: Moderate to advanced. This species demands stable water conditions 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. A diet rich in marine algae and seaweed is vital, supplemented with high-quality herbivore pellets and occasional meaty foods.
Minimum Tank Size: At least 180 litres (approximately 50 gallons) to provide ample swimming space and reduce territorial behaviour.
Reef Safety: 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 and moderate to strong water flow to mimic natural reef conditions.
Placement: Best suited to larger, well-established tanks with plenty of live rock for grazing and hiding spots.
Origin: Indo-Pacific region.
Maximum Size: Up to 30 cm (12 inches) in length.
Providing a varied diet and maintaining pristine water quality will ensure your Acanthurus lineatus remains healthy and vibrant. Regular observation for signs of stress or aggression is recommended.
