Elizabeth Hill –
I bought this grouper for my 180-gallon tank. It has been thriving for six months. I’ve had to be careful with other fish, but it’s not aggressive toward me or my larger tank mates. It’s a strong, active fish that adds presence to the tank.

The fish arrived healthy and seems to be adjusting well. I’ve kept it with larger, robust fish and avoided small invertebrates. It’s not the easiest to maintain, but it’s impressive once it settles in.
Connor Dickens –
I expected more aggression, but it’s actually calmer than I thought. Still, I removed a small shrimp that got too close. I’d recommend only for experienced aquarists with large tanks.
