It is the natural course of events for the spots to fall off before they reproduce. You may see the spots come back soon in greater numbers. I hope that the ich is gone but don't hold your breath. People that properly quarantine rarely get ich in their display tank. Perfectly healthy, unstressed fish can get ich if the parasite is present in the aquarium. Stress can be a factor, but it is not a prerequisite to infection with ich.
