I want to thank EVERYONE who has responded to this thread! I about got roasted on Facebook for even considering pretreatment for a fish that wasn’t showing symptoms. I’ve put over 30 fish through QT including sensitive wrasses and copper bands and this is the first issue I’ve had a little panic on. So thank you all!!
Facebook groups can be incredibly toxic. For whatever reason people think their opinions are the only thing that matters. I have seen people get in heated personal toxic arguments over what they are feeding their cats on there.
