Last weekend I got a Bicolor Angelfish as a tank mate for the lionfish in my 120 gallon tank. I added him to the QT tank with the other fish I got 2 or 3 weeks earlier. Two day ago most of the fish in the QT tank were showing signs of ich. I’m now certain there is ick in my QT tank . Good thing the wife started the copper meds as soon as the symptoms became visible.

Hopefully all of the fish will pull through.

I was hoping to have all of these fish in the main tank within the next 3 weeks, but it looks like they will be spending a lot more time in QT than planned
