Mine lived for about 4 years before he started to look "old" and eventually passed on. I don't know if that's a normal lifespan or short or what. Anyhow, I had him in a tank with SPS and clams and never had a problem. He had one of the biggest personalities out of any fish I've had, if I cleaned the outside glass he would chase the cloth away. Was greatly entertaining to any visitors, I could lure him out of hiding with as little as waving a paper towel in front of the tank.
