Any ideas on why the bicolor didn't get it?

Pretty much as Danny said or the fish could have had it and you could not see it. In the same tank some fish can have it so bad they die and some seemingly not infected. Also your new fish might have had Ick and you could not see it. On healthy fish it can hide in and around the gill areas and can be almost impossible to spot.

I sort of agree with Bob's theory that it is always there. Because I've had it come out of seemingly nowhere. But the ‘pros’ do state different...strict QT, hyposalinty treatment for infected fish and fallow water for six weeks. Their logic is strict laboratory scientific study. Where I can't agree with you Bob is if Ick Kick works, how can it be still present in the tank...it simply didn't work.
