Easy to care for and very active in the tank. The fish has bright colors and is a great addition to a reef setup with an anemone. Feeds well on frozen and live foods.

Stable in my 30-gallon tank with a sea anemone. The coloration is vivid and it seems to enjoy the environment. A bit shy at first but settles in quickly.

Perfect for beginners. It’s hardy and doesn’t cause stress to other fish. I feed it a mix of brine shrimp and spirulina daily and it thrives.
