I’ve kept this anthias in my 75-gallon reef tank for six months. It’s very peaceful and doesn’t bother the corals. The fish has grown to about 3.5 inches and looks vibrant. Only needed a few weeks to adjust to the tank conditions. Highly recommend for experienced reef keepers.

The Princess Anthias is a beautiful addition to my tank. It’s calm and doesn’t chase other fish. I had to ensure the tank was large enough, but once settled, it’s a great fit. A bit shy at first, but now it’s active and healthy.

After adding this anthias to my 70-gallon tank, I noticed it blends well with the reef environment. It’s not aggressive and stays near the lower areas. I appreciate the detailed care notes provided. Easy to maintain once the tank is stable.
