Black ich: inverts, blennies, and formalin

I've got a yellow tang that looks like it has black ich. There are also 2 nassarius snails in that tank. I'm thinking about plopping the snails into another tank, but wondered if they could carry the black ich with them?

I also have a lawnmower blenny in the same tank. As far as I can tell it doesn't have the black ich, but honestly, who can tell with it's mottled coloration? Should I treat the blenny too?

I'm probably going to do a formalin dip for treatment, but I'm unclear as to how this prevents the fish from getting re-infected after the dip. Anyone know the answer?
