Am I correct that the *only* Ich risk with adding any invert is that a *tomont* stage cyst could be somehow attached to the shell, live rock, coral plug, even (in theory) soft tissue of a sea hare? Assuming you rinse or dip, there is no way a theront could hitchhike, correct?
If that is the case, and assuming you maintain a dedicated fish-fallow invert QT tank, am I correct that each individual item (snail, crab, coral with plug) needs to spend 72 days in that tank, but those can periods can run at separate times. For example, on day 70 of a period for some snails, you can still add a coral to your QT, then remove the snails 2 days later and put them in DT, because (a) you know that any tomont that came attached to the snails is gone and (b) any tomont from the coral is still a tomont or has hatched to a theront, which cannot attach to the snails and has no fish host to latch to and dies.
Sound thinking? Or does everything that goes in an invert QT tank re-start a new 72 day period? Seems insanely unlikely that a free swimming theront in a fallow invert QT tank could attach to a snail shell.
