honestly i dont see the point of QT'ing inverts. ich does not affect inverts but can be carried "on" them. because of this there are no outbreaks and you wont know they are there. and the only way to destroy the ich is to treat with hypo which would kill the inverts, as well as anything live on the rocks.
Correct, ich does not effect inverts. However, when ich reproduces it attaches to a calcareous surface. That surface could very well be an invert shell. You would not have to treat the invert in QT because the ich will die after it reproduces. It will not have a fish to feed from. If you were to introduce an invert into your tank without quarantine then when the ich does reproduce it will have all of your fish to feed from and infect.
You should quarantine everything for three weeks (the amount of time it could take an ich parasite to reproduce) to be sure that you do not introduce unwanted things into your tank. I know it seems like a pain but it is a much bigger pain to have to catch and move all of your fish for treatment. Believe it or not, parasites are introduced on non fish all of the time.
