Quarantine question?

[burtonpj48]

Hello Everyone!!

I have a question regards to quarantine procedures. When do you take the fish out from the display, for example treating itch. Do you let the fish try and fight it, on its own. The second you see itch, do u already remove the fish from the display. My concern is if i let it fight it, other fish may catch it. Would like to know what other peoples opinion regards to the matter. Thanks.
