Utter rubbish, just another fish mythduanes;2450061; said:You can fool ich into hatching out in a fishless tank, where, because the tomites don't find a host, will die. Just add some water from a tank with fish into the fishless tank. Either pheromones or waste products (don't know for sure which) from the fish trigger the ich cysts into "hatching" into a hostless enviroment.
It is theorized that some cysts may lay dorment for months, maybe years, though, and may survive in dust.
ICH doesn't lay dormant, in a fishless environment it will die out... Period.
In cold water it's life cycle can take a extended period to complete, just as warm water speeds it up.
ICH can manifest as a 'Latent' infection, which is oft mistaken as dormancy.
