Received the fish in good condition. It’s active and peaceful in the 60-gallon tank. I’ve kept it with some soft corals, and it hasn’t damaged any of them yet. A good choice for intermediate reef keepers.

The fish arrived healthy and seems to adapt well. I noticed it’s not aggressive and stays near the back of the tank. I’m cautious with the coral placement, but so far no issues.

Perfect for a beginner-intermediate reef setup. It’s calm and doesn’t chase other fish. The size is small, so it fits well in a compact tank without overcrowding.
