The terminology is really not relevant on this issue so it's pointless to even argue about that. A container could be a tank, bucket, jar, etc, which people may use to QT. You do not HAVE to QT in a "tank". Seeding new tanks (containers, whatever) does not auto cycle. The BB still have to colonize and adjust to the params so unless you move enough filter media to crash your other tank, you do not have an auto cycle and your fish may still be subjected to slight param changes.
Because the original question was in context of a very specific forum, I am not incorrect by my response that is applicable to that context, meaning that unless you are breeding or have a ton of fish, it is unlikely that a person on that particular forum has the kind of resources available to use the method you suggest. Judging by the fact that it is only a few tetras and not more than ten suggests to me that there is a chance that this person MAY not have those kind of resources. I never suggested that it was a good idea to QT fish in a uncycled tanks "so that" diseases may manifest, I merely pointed out that diseases are MORE LIKELY to manifest in a slightly less than perfect environment. There is absolutely nothing wrong QTing in an uncycled environment as long as you monitor carefully and keep up with water changes. The fact that you assume that "most people" have larger quarantine tanks than main tanks is a little bit ridiculous. Unless you go and poll every fishkeeper of every scale and experience level, that is an incorrect assumption. I know of a great many people who choose not to do it this way and have healthy active aquariums. If you want to argue that, then go ahead and give us some credible statistics and studies.
And you are correct: being a mod does not mean having more legitimate information as much as having years of fish experience does not indicate correct information, obviously.
Just because my opinion is different than your does not mean that I am less informed, "confused", or wrong. I was merely stating my opinion for the questioner to compare with. If you want to continue to be condescending and combative, go right ahead. I am not intimidated at all.
