Don't laugh!! I feel like this is a dumb question, but I'm curious
I'm not dealing with ich now, but surfing the treads made me think. I always hear of fish like tangs getting ich when they are introduced. But if you get rid of the ich in the tank on all fish in the tank and, is it possible for the fish to get ich a few months down the road if stressed? I doubt it, since the ich was all killed months ago, just curious.
