The fish arrived healthy and vibrant. It has been in my 120-gallon tank for three months and is very active. The yellow and charcoal colors stand out beautifully. I appreciate how calm it is and doesn’t bother other fish.

Great addition to my reef setup. The coloration is impressive and it blends well with the coral. I’ve noticed it swims gracefully and doesn’t chase other fish. A bit shy at first but now it’s a regular sight.
