So serious question then...if part of controlling disease is reducing stress on my fish...wouldn't it make more sense in my case to just treat my display tank with Paraguard? All of the fish are still actively eating...I feel like moving them from current tank to QT is going to stress them out even more. I don't mind if some snails or crabs die...I could also move my corals out for the time being as they are just frags if those would get affected as well. I just want to do what's right knowing that what I've already done is wrong, aka lesson learned for the future.
Not at all. First off, Paraguard isn't a viable way to cure Ich despite what the manufacturer claims. Copper or CP are your best bets. The "stress" factor is way over emphasized. Having Ich is more stressful.

Last week I moved the 5 remaining fish back into the DT after it had been fallow for 76 days and the fish had been treated w/ Cupramine in the QT. It could've been better, it could've been worse, but I learned a lesson and hopefully that lesson will allow for me to not lose anymore fish moving forward.
