I’ve kept this lionfish for six months in a 30-gallon tank. It’s active and curious, but I’ve had to monitor its behavior closely. It doesn’t harm the corals, but it will chase small fish. I’m happy with the purchase and the size fits well in my tank.

The lionfish arrived healthy and seems to adapt well to the tank. I’ve placed it in a tank with a few larger fish, and it’s not causing any issues. Just keep an eye on smaller species around it.

It’s a bit aggressive at first, especially when feeding. After a week, it settled down. I’m not sure if it’s fully compatible with my current reef setup, but it’s not causing major problems yet.
