Bought this for my 120-gallon tank. It’s been a few months now and it’s active but not overly aggressive. I keep it away from small shrimp and snails. It does eat a lot, so feeding needs to be consistent. Overall, it fits well in the setup with proper space.

The fish arrived healthy and vibrant. It’s a bit large for a beginner, but I have the right tank size. It’s not shy and shows interest in the environment. I’ve had to adjust feeding to match its appetite, but it’s a great addition to the reef.

It’s aggressive toward smaller fish in the tank. I had to remove a few small gobies after a week. I’m keeping it in a larger tank now and it seems to be settling down. Not ideal for small setups.
