No offense meant Crab, I was just pointing out that what you were recommending was more for acclimation than for QT. You segued from saying that your QT procedure varied from fish to fish and then dove into how you used your fuge for acclimation. I pointed out the difference for inexperienced reefers who might find the thread and misunderstand, thinking that using a fuge or an in-tank basket actually provides an effective quarantine from pest or parasites.
In my experience, early on I purchased a small Kole tang from an LFS. Upon getting it home, I acclimated it and dropped it in my 90g tank. Immediately upon seeing it hit the water my actinics picked up dots of white all over the fish. Argue what you will about ich, but I had never had it on my fish prior to them being exposed to the new tang. Within three days half of my fish were dead including my favorite 5" long green mandarin that ate frozen. I was devastated. Quarantining him upon purchase for a few weeks would have allowed me to observe him in a more contained environment and upon seeing the ich I would have been able to treat him without fear of medication effects on my main tank.
Likewise, a few months ago one of my newly acquired clownfish came down with cotton-mouth. I was able to put him in the eclipse and treat him until he recovered.
I agree with you that most fish we purchase often won't be bothered nearly as much by parasites as they will from the shock of being dropped in a new tank and finding their niche in the pecking order. All of our goals are the same, to add healthy fish to our tanks at times and to insure that the fish prosper as well as to safeguard our existing livestock. We just do what we can to try and prevent new reefers from suffering fish losses.
