The Convict Tang (Acanthurus triostegus) is a popular choice among marine aquarists due to its bold black and white striped pattern and active swimming behaviour. This species is native to the Indo-Pacific region and is well-suited to community reef tanks, provided its care requirements are met.
Care Level: Moderate – suitable for aquarists with some marine experience.
Temperament: Generally peaceful but can be territorial towards conspecifics or similar tang species. Best kept singly or in a large tank with ample swimming space.
Diet: Herbivorous – primarily feeds on algae. Supplement diet with marine-based seaweed sheets, spirulina, and vegetable matter to ensure optimal health.
Minimum Tank Size: 120 litres (approximately 30 gallons) to provide sufficient swimming room and maintain water quality.
Reef Compatibility: With Caution – generally reef safe but may nip at some soft corals or clam mantles. Monitor behaviour closely in reef setups.
Lighting and Water Flow: Standard reef lighting and moderate water flow are ideal to mimic natural habitat conditions.
Placement: Mid to upper levels of the aquarium where it can graze on algae and swim freely.
Origin: Indo-Pacific region.
Maximum Size: Up to 25 cm (10 inches) in length.
Regular water changes and stable water parameters are essential for maintaining health. Avoid aggressive tank mates and provide plenty of live rock for grazing and hiding.
