BTW Jaybird I was not saying you said that I was just pointing that out to the OP. I knew what you meant.
No worries and nothing taken in any way other than trying to give the OP the best possible info.
The white that you see on the fish is the cyst, which is feeding off the fish. When that releases there will be a whole lot more of the parasite in the tank. The ones released from the fish will go down to the substrate, rocks, etc, and be dormant for a little while. Then they will become free-swimming and look for another fish.
