I bought this fish for my 20-gallon reef tank and it has been thriving for over six months. The colors shift beautifully throughout the day and it adds a lot of movement without being aggressive. I’m happy with the choice and would recommend it to others starting with marine fish.

The fish arrived healthy and seems to adjust well to the tank. It’s active and curious, and doesn’t bother the corals. A good addition to a small reef setup.
