The fish arrived healthy and active. It has adapted well to our 60-gallon tank. We monitor it closely due to reef compatibility warnings. It’s peaceful and doesn’t bother other tank inhabitants. A good choice for intermediate reef keepers.
Faith Greene –
We’ve had this fish for three months now. It’s calm and stays in one area. We removed a small anemone after a few weeks, which we believe was due to the fish’s activity. Overall, it’s a manageable addition to our tank.

The size is slightly larger than expected. It’s active but not aggressive. We keep it in a mixed reef setup with caution. It’s a solid pick for those with intermediate experience.
