Luckily everything is back to normal now. I treated with therapeutic levels of copper for about 4 weeks then returned them to my main tank. One issue I had was that the quarantine tank wouldn't drop below 81 degrees. After reading that warmer temperatures help eradicate disease, I think that may have helped get them better in the limited timespan that I was able to have a quarantine tine. They are both alive and doing well
I truly appreciate all the help!
