The fish arrived healthy and active. It’s peaceful and has not shown any aggressive behavior. I’ve kept it in a 55-gallon tank with a mix of corals, and it’s been fine so far. Only needs occasional feeding and is easy to spot in the tank.

It’s a beautiful fish with vibrant colors. I noticed it occasionally nips at a soft coral, so I’ve added a barrier. Overall, it’s a good fit for a reef tank with proper monitoring.

I’ve had this fish for three months now. It’s active, stays in one area, and doesn’t stress other fish. The care level is manageable, and it’s a great addition to a mid-sized reef setup.
