A great species for robust fish systems, I have kept several over the years with great success. One of my all time favorites really... just make sure you get one from Australia if possible, look for the blue trim. http://www.wetwebmedia.com/marine/fishes/wrasses/choerodon/faciata.htm
I have a tusk in my 75. He is a great fish to sit and watch. Very active in the tank. Very hardy fish from what I have heard. He shares the tank with my picasso trigger. I'll try to get a pic up once I get home, right now I'm surfing at work.
