Yowsa... I'd be worried too. They're probably all well tempered now because they're living in a 180g. I'd get a bit cranky if I went from a 1500 square foot apartment to a 500 square foot studio overnight, like you're thinking about with your fish.
I can understand why you wanted substrate and rock in the QT - to make it more like "home" for their extended stay. But it really will cause an issue if you medicate it. Do throw in some PVC
elbows and "Y"s though... that will give the fish some places to hide and feel secure.
Personally... I wouldn't move everything and medicate for no reason. What's done is done. But I WOULD quarantine everything else from now on. And if somebody does look like they're having a problem, then be ready with plan.
[Edit: Looked at your other post - nice setup! Only thing I was going to comment on, you already commented on yourself - your lighting. That's the only thing I thought when I looked at the pics - "That light seems really narrow". But I understand what you mean about the center MH
with the center brace. Not familiar with acrylic tanks or MH
, so maybe someone else can comment!]
