Austin Randall –
I bought this Panther Grouper for my 180-gallon tank. It’s aggressive, as expected, and has been territorial with other fish. I kept it separate from corals and it’s now a dominant presence. Water parameters are stable and it seems healthy. Not for beginners, but great for experienced aquarists with large tanks.

After a few months, the grouper has grown to about 6.5 inches and is active in the tank. I’ve avoided placing it near delicate corals. It’s a striking fish and adds visual impact. Maintenance is manageable with regular water testing and feeding.
Austin Bond –
It’s aggressive and I had to reposition some fish to avoid conflicts. The tank is large enough, but I wish it came with more guidance on compatible species. Overall, it’s a bold choice for a mature reef setup.
