Trevor Johnston –
I bought this grouper for my 120-gallon tank. It’s been two months and it’s active but not overly aggressive. I keep it in a well-structured tank with plenty of hiding spots. It does eat a lot and needs regular feeding. I’m happy with the size and appearance, though I did have to remove a small polyp after a few weeks. Overall, it fits well in the setup.

The fish arrived healthy and seems to be adjusting well. I’m cautious about keeping it with other species. It’s not shy and tends to dominate the space. I’ve added more rock structures to give it room to move. It’s not the most peaceful fish, but it’s visually striking.

I’ve had this grouper for three months now. It’s grown steadily and looks great. The tank is large enough, and I’ve avoided keeping it with small fish. It’s active and eats well. I do monitor the coral closely, and so far no major damage has occurred.
