I bought this grouper for my 120-gallon tank. It’s aggressive and needs a strong setup, but it’s a striking addition. I’ve had to remove some delicate corals, but it’s active and visually impressive. Feeding is straightforward with frozen shrimp.

The fish arrived healthy and is active in the tank. I’m cautious about keeping it with other species. It does dominate the space and requires a well-maintained environment. Not for beginners.

After a few weeks, it’s established in the tank and shows good coloration. I keep it in a large, stable system with no reef inhabitants. It’s a bold choice, but worth it for the visual impact.
