If you plan on doing the treatment in 2 stages, I'd recommend the tangs are in the first bunch. they are more suseptible to ick due to their lighter slime coats. But that means the other half stay in the 120 for an extra 2-3 weeks (or whatever the treatment calls for) plus an observation period (you don't want any ich to survive and make it to the 55.
I'd probably go with treating the entire school at one time, and then split them up after as you feel is appropriate (perhaps easier to catch fish get into the 55) once the single treatment is done.
as for the 120, the inverts can stay, they will not host the ich.
Good luck.
