Although corals/inverts can "house" ich for up to 72 days, they cannot host the way a fish can. Denying the parasites a host to feed upon is the key to starving it out of your DT. So, all corals/inverts can remain in the DT... but all fish need to be removed, QT'd and treated for ich.
I thought I read somewhere that you can add corals to an already existing coral QT and NOT restart the 72 day clock. This does not make sense to me because aren't you running the risk of new parasites that can transfer to the corals that are already in the QT?
