I have at least 70lbs of live rock in my 47 with a thriving Mandarine Goby that is the prize of my tank. I've had him in my tank for about 7 or 8 months. Put him in before I knew to WAIT! but I guess there is an exception to EVERY rule! He stays out in the open just grazing away all day. He'll stop and turn his head to look at me when Im watching! He's great!
But like I said (exception) ! I would'nt have gotten him had I known. I trust most of the advice here! Thomas, Bang, Kip, :cheer:
Good luck
