I have one and he's been great! It's interesting watching him change colors when he hides. We had a community tank with him, a dwarf lionfish, a blue tang, and a heniochus. He didn't pick on any of them and the others left him alone too. After a few months the blue tang went around nipping on the others fins but the fox face was the only fish he left alone. I have heard he would be fine in an aggressive tank too. Mine has never bothered any cucumbers, corals, anenomes, inverts, etc. He's also been very hardy. Definitely one of my favorite fish!
