The fish arrived healthy and active. It’s peaceful and doesn’t bother other tank inhabitants. I’ve kept it in a 55-gallon reef tank for three months now and it’s thriving. The coloration is vibrant and it’s a great addition to the community.

It’s a beautiful fish with a unique appearance. I was cautious about adding it to my reef tank, but it’s been fine so far. Feeds well on small crustaceans and doesn’t show signs of aggression. Needs a stable environment though.

Perfect for intermediate reef keepers. The fish is calm and stays in the middle of the tank. I’ve noticed it’s more active during feeding times. It’s a standout in the tank and looks great with the live rock.
