Why are you even talking about Prazi? That is for flukes, not ich. You've got ich. I disagree with everyone who says to let them be because the stress will lower their immunity further and they will die. I'm my 15 years of keeping fish, I've only been successfully by treating with copper in qt and letting the DT go fallow. Also, you need to act quickly because as the fish relax in their stress free ich infested house, they will be getting sicker and sicker and copper is less likely to work when you eventually try that remedy. Good luck, ich is terrible.
