Keith Rutherford –
Bought a tiny Polleni Grouper for my 100-gallon reef tank. It’s active and curious, but I’ve had to remove a few small fish that were too vulnerable. The water parameters are stable and the grouper seems healthy after a few weeks. Aggressive behavior is noticeable, so I made sure to keep larger, robust fish as companions.

The fish arrived healthy and is now settled in. I’m cautious about adding new fish due to its aggressive nature. It does not eat much and seems to prefer hiding during the day. Good for experienced reef keepers who understand the risks.

This tiny Polleni Grouper has been a fascinating addition to my tank. It’s not the most social fish, but it’s active and adds visual interest. I’ve avoided keeping it with small shrimp or gobies. Overall, it’s a bold choice for intermediate reef setups.
