Yeah...the guy I mentioned that I got a frag from off the SPS forum here didn't QT some coral he got at some point in time and it cost him his whole tank of SPS, literally thousands of dollars of corals - large colonies. He had to start over. When it comes down to something like that, if I lost my whole tank there's no way I'd be able to afford to start over. With that in mind, that's why I set my 10g tank up as a small display that is also capable of sustaining SPS corals in a sort of QT for observation before going to my big tank. It's like my reef condom. Not paranoid, just aware of how many of the "big SPS'ers" on RC who have succumbed to these bugs and learning from their experience. If I had not, I would have just recently introduced a new frag to my tank that was nicely populated with redbugs.
