The Acanthurus polyzona, or Zebra Surgeonfish, is a visually captivating tang distinguished by its bold black and white horizontal stripes. This medium-sized marine fish is a popular choice among experienced aquarists due to its active swimming behaviour and striking appearance.
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 surgeonfish or similar-shaped tangs, so careful consideration of tank mates is essential.
Diet: Primarily herbivorous. Provide a varied diet rich in marine algae and seaweed, supplemented with high-quality herbivore flakes or pellets. Occasional meaty foods 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 aggression.
Reef Safety: With Caution. While generally reef safe, this tang may nip at certain sessile invertebrates or corals, especially if underfed or stressed.
Lighting and Water Flow: Standard marine aquarium lighting is sufficient. Moderate to strong water flow mimics natural reef conditions and supports the fish’s health.
Placement: Provide plenty of live rock for grazing and hiding spots. Ensure the tank is well-aquascaped to reduce stress and territorial disputes.
Origin: Not Provided.
Maximum Size: Approximately 25 cm (10 inches) in length.
Overall, the Acanthurus polyzona is a rewarding species for marine hobbyists prepared to meet its specific care requirements. Regular monitoring and a balanced diet will help maintain vibrant colours and robust health.
