I just fail to understand the camps tha taut no qt, but a stellar diet. I feel that probiotics, fresh ingredients, high variety, frequent feedings, and clean water as the norm, but utilized with qt gets you the benefits of both camps.
I don't think no-QT is part of the agenda....it may end up a natural side-effect though.
Just as it's important to distinguish what kind of "immunity" we're talking about (post
[HASHTAG]#207[/HASHTAG] again) I think we need to be clear about the type of QT.
A QT can be as right or wrong as the person googling "QT FISH" and setting it up.
If your QT is another display tank, just apart from your primary display....then you can QT until the cows come home if you want. (I'd have to google "COWS COME HOME")
If your QT is a bare tank laced with copper...well. That should be more like a dip.
I personally don't keep many prs of fish,

You are already three legs up over anyone who's ever posted a wipeout thread.
Posts that encourage people skipping qt are exactly what new aquarists want to hear.
Posts that make people think there's a magic bullet of any kind are what noobs want to hear.
What I think they might not totally mind, is if they were asked not to stock the tanks
so full or
so fast.
Allow yourself to be a beginner with a single (or very few) fish for a year or two or three. QT if you want (within said limits of good sense).....after that period of time, you will be almost impervious to "tank wipeout threads" due to your own experience and the resistance you've been able to establish in your fish.
"Go slow" for most seems to mean
driving the speed limit to go pick up your box of fish.
I don't care how good (you think) your QT is, there's no expertise showing up with that box!
