Tank transfer from Display to quarantine fish not eating

I found my fish had ich and so I took the main water and transferred that to the quarantine tank and put them in that with copper. But before I transferred them they were eating everything and fine. Now they wont eat and have very fast breathing.

Everything is matching the display tank where they came from and all other fish are doing fine. I added an air-stone today to see if that will help.

I believe copper can suppress appetite.

FWIW if you have other fish in the DT then they need to be treated as well.

I was only able to catch the larger fish in my display, the tank is 500 gallons and would be very difficult to catch the smaller ones.
