I've had one in my reef for over 2 years. Gets along fine with everyone else. Yes he is territorial, and thinks he is a big bas-a**, but does not seem to bother any of the other inhabitants. The clowns actually have a game where one of them goes near his rock, gets chased out and the other one goes in from the other side. They go back and forth for a few minutes. Funny to watch!!!
