I have a tank that just had a very bad ich outbreak. I had taken my QT
down a few weeks before because I was not introducing any new fish and everything in the tank looked healthy. I lost a few fish before I could get the QT
My question is, my only two remaining fish are a firefish and a snowflake eel. Neither of these show any signs of ich at all. I have them in QT
now so that my display can sit for 6 weeks fishless. Do I need to treat these two fish if they do not show any signs of ich? Will I need to do anything before I return them to my main tank? Please let me know.
