You introduced him/her into a tank with fish known to have ick. That's just irrisponisble. When I fish is first introduced into a new home it's at it's most vonerable to disease. When I fish is stressed (and would be simply by the move and change in water chemistry) they're immune system becomes week. And now you have moved him/her again.... good luck saving her, make shure to add salt and boost temps right away.
I think he meant that sarcastically.. hope that's the way you took it..
