Bought this clown grouper for my 120-gallon tank. It’s active and curious, but I had to remove a few small corals due to its aggressive tendencies. Still, it adds a lot of visual interest and is easy to care for once the tank is stable.

The fish arrived healthy and fits well in my 100-gallon reef tank. It’s not the most peaceful, but it’s impressive in size and color. I’ve kept it with larger, robust fish and it hasn’t caused any major issues.

I expected it to be more aggressive, but it’s actually calmer than I thought. Still, I had to remove a few small invertebrates. It’s a good choice for experienced reef keepers with space and patience.
