The Lieutenant Tang (Acanthurus tennenti), also known as the Naso Tang or Lipstick Tang, is a striking fish native to the reefs of the Indo-Pacific. This species is celebrated for its vibrant blue body, accented by a yellow tail and facial markings that resemble a “lieutenant’s insignia,” giving it its name. The combination of these colors makes it a stunning centerpiece in any marine aquarium.
Lieutenant Tangs are known for their playful and curious nature, often seen swimming gracefully through the water. They thrive in environments that mimic their natural habitat, requiring plenty of swimming space and robust rock structures for hiding and grazing. Their semi-aggressive temperament means they can coexist with other moderately tempered species, but caution should be taken when introducing them to smaller, more docile fish.
As herbivores, Lieutenant Tangs primarily feed on algae and plant material. It’s essential to provide a varied diet that includes high-quality algae sheets, spirulina, and other marine plant foods to maintain their health and vibrancy. Regular feeding multiple times a day will help ensure they receive adequate nutrition.
With a maximum size of 8″, Lieutenant Tangs require a minimum tank size of 100 gallons to accommodate their active swimming behavior. They prefer stable water conditions and should be kept in aquariums with proper filtration and regular maintenance. The Lieutenant Tang is a great choice for aquarists looking to add a beautiful and engaging fish to their reef system, as they are generally reef compatible and known to be resilient to varying water conditions.
