It's not the inverts that could carry the parasite, it's the water. I once had one ICH tank which my housesitter spread to my other tanks with a damp net! I've even got a Derasa clam waiting out the six weeks it takes the parasite go through it's life cycle. I QT sand, rocks, inverts, everything that's wet. As far as how long, you add it up...the life-cycle of the ICH parasite without a fish is:
1.TROPHONT FREE SWIMMING: This is where the parasite has dropped off of the fish and is free swimming within the water looking for a suitable place to attach to so that it can form itself into the Tomont or reproductive stage, which can take up to 18 hours.
2.TOMONT STAGE: This is where the parasite forms a membrane while attached to the substrate and goes into its reproductive mode, this can take from 3 to 28 days depending on the temperature of the water.
3.THERONT STAGE: This is where the newly hatched parasite is free swimming in the water and is looking for a fish to attach to. It only has between 24 to 48 hours to do so or else it will die.
Without a fish being present...the theront is DEAD and the life cycle is broken. If you QT inverts with fish, then you must either use hyposalinity or medication. Without fish the last part of the cycle,
(The TROPHONT STAGE: This is the adult parasite which is attached to a fish and actively feeding and the one that we can visibly see on a fish. This stage lives from 3 to 7 days) can't occur.
Minimum time: 31 days.
