Tank Mates: Reef safe, will ignore the majority of other fish, invertebrates and corals. Can be moderately aggressive toward other fish in the same family, especially fish of similar or smaller size. If adding to a smaller tank with other small inhabitants, is generally best to introduce to the system last, to help avoid any aggressive tendencies.
Long one of my favorite fish, I acquired this from a fellow reefer who was shutting down his system. He had the fish in his system for close to 8 years, I had it in my 24G AquaPod for nearly 2 more years... unfortunately, this fish passed away in early June, 2012.
