Hiya, was in my LFS late last night to hand over my last batch of BN babies & on leaving I spied a single Cory all on his lonesome so obviously couldn't leave him there and brought him home to be with some friends, I then noticed he had what I figured was the start of fungus on a fin so I treated the tank as per my fungus med....however I've since read that Cory's & meds don't mix well.....so do I pull out all the meds (Carbon & water changes etc) tonight or will it be ok, he does seem to have slightly improved overnight...?
