The Orange Shoulder Tang arrived healthy and vibrant. After setting up my 80-gallon tank, it adapted well within a few weeks. The coloration is striking, especially the orange shoulders that stand out in the water. It’s peaceful and doesn’t stress other fish. A great addition to a reef setup.

I’ve had this tang for three months now. It’s active and maintains its bright colors. The tank is 75 gallons, and it’s thriving. I do need to be careful with feeding and avoid overcrowding. Overall, a satisfying purchase.
