Thanks for chiming in all. I kinda agree with "random fish guy" that a 120 might not be a good idea for a fish of that magnitude. From the responses above it seems like its a crap shoot. Well not going to risk it in my mixed reef, but I would definitely try it in a sps tank. I'm curious though, does it have a good personality? My CBB and my pacific blue tang have great personalities. I definitely enjoy a fish will good personality!
