I just found out I have got ich in my display tank, and they were the last fish I was going to add my my tank. I quarantine all my fish for 10-15 days but I guess that’s not enough. The butterflies I got had the ich dang. Now I’m dosing cupramine into the display tank. I hope it will be fine. I want to ask is cupramine the best for totally taking out ich. I also raised the temperature to 82-83 degrees F.
