Easy to care for and very active in the tank. The fish blends well with the reef environment and doesn’t stress other inhabitants. Perfect for a small reef setup.

Arrived quickly and looks healthy. It’s calm and stays near the back of the tank. I’m happy with the size and color match.

Great addition to my 24-gallon tank. It’s peaceful and doesn’t eat any of the corals. Very satisfied with the purchase.
