I kept one Beau Gregory Damselfish in my 60-gallon tank. It quickly became the dominant fish, which was both surprising and exciting. It doesn’t harm corals and stays active throughout the day. Feeding it meaty foods works well. Just make sure the tank is large enough and no other fish are introduced.

The fish is very active and territorial. I only have one in my tank, and it’s been peaceful since I kept it alone. It eats flaked food and meaty options. I noticed it doesn’t eat much of the herbivore food, so I adjust the diet accordingly.

It’s aggressive and I expected that. I kept it in a 50-gallon tank and it didn’t cause any issues with the reef. It’s not for beginners, but if you have a large tank and know what you’re doing, it can be a great centerpiece.
