Not necessarily, ich drop off the host when they've had enough of a meal, to reproduce in the substrate. Keeping your fish nutritionally well fed, and stress free will help them resist future infection, but only time will tell if it was ich. If it was ich, and they just dropped off to regroup, you may see it again.
