White Tail Yellow Eye Tang

The White Tail Yellow Eye Tang (Ctenochaetus flavicauda), also known as the Whitetail Bristletooth Tang or Yellow Eye Kole Tang, inhabits shallow reef slopes and lagoons in the Indo-Pacific region, where it grazes on algae and detritus. Reef-safe and peaceful with other fish, it reaches 7 to 9 inches in length and lives 5 to 7 years. To provide the best care for your White Tail Yellow Eye Tang, maintain a tank with a minimum size of 120 gallons (284 liters). This ensures ample swimming space and helps reduce territorial conflicts. Water conditions should mimic their natural habitat, with a pH level between 8.1 and 8.4, a salinity level of 1.020-1.025, a stable temperature between 74-78°F (23-26°C), and moderate water flow to simulate ocean currents. With a deep red striped body, shining white tail, and small golden circles around its eyes, it adds vibrancy to aquariums. Suitable tank mates include Flame Angelfish, Royal Gramma, Lawnmower Blenny, Six-Line Wrasse, and Coral Beauty Angelfish.
