So I'm a novice aquarist and have just encountered my first case of ICH. I don't currently have a quarantine setup so it looks like I'm going to have to go into ICH Management mode. I've seen many people say that if you just keep your fish healthy and happy that you shouldn't have problems with ICH flare-ups and it manages the disease. Others seem to think that you've got to eradicate ICH otherwise it will still live in your aquarium. In order to do that you've gotta go without fish for like 3 months in order to kill the parasite. Here is my question. If your fish stay happy and healthy and the ICH doesn't have anything to host to wouldn't that also kill them without having to remove fish from the tank? Or do the ICH still eat on your fish but they just don't cause the cysts to form on the fish because they're able to fight them off? I feel like I'm missing something here
