fish get ich more than once?

  • We are currently upgrading MFK. thanks! -neo
no, they get it as many times as the owner allows them to
 
Your solution here is either complete the 14-day treatment course against ich or start quarantining every new fish you get. Failing both, ich will reappear the moment your fish becomes stressed. They are just residing in the gill tissues. There is no dormant phase for this parasite.
