The Acanthurus nigricauda, commonly known as the Nigricauda Tang, is a captivating addition to any large marine aquarium. Recognisable by its distinctive dark tail and streamlined body, this medium-sized tang is a robust swimmer and an active grazer.
Care Level: Moderate to advanced. This species requires stable water parameters and a well-established aquarium.
Temperament: Generally semi-aggressive. It can be territorial, especially towards other tangs or similar-shaped fish, so careful consideration of tank mates is essential.
Diet: Herbivorous. Provide a diet rich in marine algae and seaweed, supplemented with high-quality herbivore flakes or pellets. Occasional meaty treats can be offered but should not dominate the diet.
Minimum Tank Size: At least 180 litres (approximately 50 gallons) to allow ample swimming space and reduce territorial behaviour.
Reef Compatibility: With Caution. While generally reef safe, it may nip at certain sessile invertebrates or corals, so monitor behaviour closely in reef setups.
Lighting and Water Flow: Standard marine aquarium lighting is suitable. Moderate to strong water flow mimics natural reef conditions and supports healthy grazing.
Placement: Provide plenty of live rock for grazing and hiding spots. Ensure open swimming areas to accommodate its active nature.
Origin: Not Provided.
Maximum Size: Approximately 25 cm (10 inches).
Adding the Acanthurus nigricauda to your collection brings dynamic movement and striking colour contrast, enhancing the visual appeal of your marine aquarium.
