I’ve had my Blue Cod Grouper for six months now. It’s a large fish and requires a big tank, but it’s active and interesting to watch. I had to remove a few small fish that were too timid. The tank is stable and the grouper seems healthy. Only recommend for experienced aquarists.

The fish arrived healthy and looks good. I’m cautious about keeping it with other species. It’s not a beginner-friendly fish and needs a lot of space. I’ve had to monitor its behavior closely to avoid conflicts.

This is a striking fish with a unique appearance. After setting up a 150-gallon tank with proper hiding spots, it has settled into a routine. I avoid keeping it with smaller fish now. It’s a great centerpiece for a larger reef setup.
