I’ve kept this boxfish for six months in a 120-gallon tank. It’s peaceful and stays in one area most of the time. I’ve had to be careful with my soft corals, but it hasn’t damaged any. The fish is active during the day and looks healthy. Only recommend for experienced reef keepers.

The fish arrived healthy and has adapted well to the tank. I monitor it closely around my anemones, and so far no issues. It’s not aggressive and doesn’t chase other fish. A bit shy at first, but now it’s comfortable in the tank.

I’m new to reef tanks and expected more stability. The boxfish is calm, but I noticed it occasionally bumps into a small polyp. I’ve since moved it to a safer corner. Still, it’s a unique addition to the tank.
