I have 2 questions about fish ich disease. Could someone teach me about them please? (1) How long will the ich trophozoite stay on the fish body ? (The water temperature is about 86 F) I did a research but could not find a certain answer that said how long would the ich trophozoite stay on the fish body until it falls off from the fish. (2) Does the high water temperature kill ich tomites ? Some people say that the ich trophozoite and tomites will die when the water temperature is raised up to 86 F. Is it true? If it is true, how long I have to keep that high temp water to kill both ich trophozoites and tomites? I'm having ich problem with my clown loach and pleco. I can not use medicine. Thanks.
