My question is, if you quarantine inverts let's say snails for example. Is the need for keeping them in the tank for 76 days needed if they are kept in a observation tank that houses a fish. Reason for asking is because if the inverts were carrying hitchhiker ich tomonts wouldn't they release and look for a host ( being my 1 fish in the observation tank ) and wouldn't that fish be the proof that the inverts did or didn't have they parasites on them. So this being my case, is 30 days in QT be enough?
