As long as you have been performing ttm right then it is just remaining trophonts jumping off the fish. They can stay on the fish for up to 7 days which you are still in.
The white spots are from when the parasites leave the fish, not new ones, just in case that helps with potential confusion.
So just keep with your plan to finish ttm and monitor for a few weeks after before putting in your DT.
Thanks for the info. I've been really careful with the water changes and the transfers but it's impossible to know 100% if I didn't accidentally contaminate the new bin.
I've read everything I could on cryptocaryon and I couldn't find out if the white spot was a part of the Ich or if it was a 'blood clot' created by the fish in response to the parasite penetrating the skin. So how does it work? The parasite enters the skin which shows no signs and then grows by feeding on the fish and then comes back out through the skin but because of the increase in size, the fish creates a blood clot to cover the opening? Or maybe the white spot is just a response when the mucous layer isn't thick enough to handle the opening because the fish is in a weakened state? Maybe this explains how an Ich population can be maintained in a system and the fish not show any spots until they are in a weakened state? Can you point me to some reference material stating that the white spot is only formed when the parasite leaves?
