I disagree. As stated in my post above, QT is fine in theory but not quite so effective in practice... for certain situations.
Take a good look at disease and treatment. 99% of posts with ich are because people did not quarantine a fish, coral, and/or inverts.
What is the most common argument that you hear for QT? People say "Might as well QT, for $100 you can save your whole display!!"
Anyone can certainly set up a quarantine tank for $100, but if the person know that he/she will be buying larger fish for their tank then it is up to the hobbyist to have an adequate qt prior to purchasing those fish.
This is the problem with the practice of QT. I would venture a guess that 99% of the people QTing are using small tanks and below average filtration. This makes QT a significant stress upon a fish and many delicate fish don't make it through the process.
If the quarantine tank is stressful then it is set up wrong. The quarantine tank should be a place that is stress free. The fish get time to adjust to your schedule and the foods that you feed, without other fish to compete with over food and territory.
Not to mention that ich (which is what most hobbiests are paranoid about) is relatively easy to treat in an otherwise healthy system.
In certain systems yes, if there is not a fish with a weakened immune system. Again, you have a FOWLR tank, as do I. How do you treat ich? What would you suggest for a reef?
There are very few absolutes in this hobby. Many on here argue that to not QT is reckless (or Russian roullette). However I would argue that it is far more reckless to purchase any livestock online (sorry SWF). To blindly order a fish without seeing it's physical condition, behavior, eating habits and size is absolutely crazy to me. But people here don't seem to mind this type of gamble yet suggest that not QTing is somehow irresponsible and there's no real debate about it.
I personally would never purchase a fish without seeing it's behaviors first. I agree with you here. Normal behavior does not mean that it cannot carry a parasite into your tank though.
As to your suggestion of the statistics regarding longtime hobbiests, I will just say this. I have been in this hobby for 2/3 of my life and I'd put my own stats up against anybody on this board... period. Again, there are very few absolutes in this hobby. When you are in it long enough, you can judge for yourself what's best for a specific type of system.
I do not doubt that your tank is healthy. I also do not doubt that you have small levels of parasites in your tank. Many sites state that their can be a balance in larger, healthy, systems of parasites and fish. I ask you to take a good look at this forum though. Every day there is a new post about ich. They always mention that they "forgot" to qt, or they knew that they should have, but didn't. It is sad. They then have to set up an un-cycled qt in the hopes of saving their fish. Google quarantine tanks. See how much of the reefing and hobbyist world finds quarantine a necessity.
