I kept this grouper in a 100-gallon tank with careful planning. It’s aggressive, so I removed several small fish. It’s active and adds visual interest. Needs a large tank and stable water conditions. Worth it if you’re experienced with reef setups.

The fish arrived healthy and is active in the tank. I’ve had to monitor its behavior closely. It doesn’t get along with smaller fish. I’m satisfied with the appearance and size, but it requires constant attention.

After researching thoroughly, I decided to add this grouper. It’s impressive in size and looks natural in the tank. I’ve maintained stable water parameters and it’s thriving. Aggressive, but manageable with proper tank design.
