I’ve kept Princess Anthias in a 70-gallon reef tank for over a year. They’re active and peaceful, and don’t bother the corals. The tiny size makes them easy to spot and manage. Only recommend for experienced reef keepers.

The fish arrived healthy and stayed calm in my tank. I had to maintain stable water parameters, but once that was set, they adapted well. Great addition to a mature reef setup.
