With Ick the tomite is the swimming stage when these parasites become infectious to fish. During this stage of the ick life-cycle their function is to find a host fish, or die trying. After they attach to the gills or body of a fish, they develop into the second stage, the parasitic trophont. During this stage they burrow into the fish, feeding on it’s tissues, which can cause considerable damage and even result in a secondary bacterial infection on the infected fish. Once well fed the trophonts stop feeding and develop cystic coverings. This becomes the inactive tomont stage and during this final stage the cysts may stay trapped in the mucus of the fish, or fall off and sit on the bottom of the aquarium. Within 6 to 10 days hundreds of new tomites emerge looking for fish hosts and the cycle begins all over again, and again and again until something is done about it. The only time this parasite is vulnerable is during their free swimming stage. The standard treatment for Ick is copper sulfate and hyposalinity.
Please be aware that your whole tank is infected at this point.
In order to suggest a treatment course, if you need help with that, you will need to give us info about your tank. Is it fish only, reef, do you have live rock, live sand? Do you have a separate hospital tank or not, are you keeping any inverts?
