John Wallace –
Bought this grouper for a 100-gallon reef tank. It’s quite active and needs a strong setup. I had to remove a small clownfish after a few weeks. Still, it adds visual interest and is a good centerpiece. Needs space and careful monitoring.
Julian MacLeod –
It’s aggressive and not suitable for a mixed community. I kept it with only larger, robust fish. It’s a striking fish, but requires a lot of attention and a well-established tank.
Sam Mitchell –
The fish arrived healthy and grew steadily. I’ve maintained a large tank with good water parameters. It’s not shy and dominates the space. I’m glad I went with it despite the aggression.
