This tang is vibrant and active in a 180-gallon tank. The coloration is striking with clear gray and yellow markings. It’s peaceful with other fish and eats algae regularly. Needs a well-maintained environment with stable water parameters.

The fish looks beautiful and is a great addition to a reef tank. It’s not overly aggressive and blends well with other tangs. Feeding it daily with algae sheets keeps it healthy and active.
