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.

Compatible Tank Mates:

I bought this White Tail Yellow Eye Tang here and to show you how hardy this guy is, he was the most active of 5 fish I had delivered when outside temp in MN was 21 degree out and bag water was at 68 degrees. All survived after 2 1/2 hr slow drip acclimation. He is a colorful little guy to watch darting around the tank. He is constantly on the move searching for food or detritus on the bottom as well as on reef rock. Likes to dart in and out of rock. He is getting much better at snagging Mysis shrimp I drop in before the other 6 fish hog it all, especially my Hamlet Indigo who gobbles everything that moves. A joy to watch.
