Scooter, as a vet, you have the advantage of being able to give injections. True, QT, seems to be the sensible thing to do. However, I lost a powder Brown Tang in QT last month in QT and lost my beautiful A. bicinctus female in QT- dead on the bottom today when I came home from work. On the contrary, I added 3-4" Blue-Chin Trigger (BCT) directly to my DT along with a 3-4" Pink-Spotted Goby (PSG). I watched the BCT for 3 weeks at the LFS before purchasing him, and felt he was too shy to risk placing him in QT because of the stress. The PSG was probably a mistake, but I did not want this sand-sifter in a bare-bottom tank for 3 weeks. The point is, my last 2 fish in QT died, and my last 2 fish to go directly into the DT have done exceedingly well. Maybe, I am just playing the odds, but as I said in my comment earlier in this thread, others with more experience feel that QT is VERY stressful to the fish.
