Hello, I have a tank that has been struggling with ich for months, there are fish in it that seem unaffected and are doing fine (hippo, wrasse, clownfish, eel), but other fish have terrible outbreaks. I moved this porcupine to a hospital tank and have been treating him with paraguard. He was getting better and seemed almost clear and then suddenly got way worse. I did an hour dip at a higher level according to the bottle yesterday and now he seems even worse. Am doing daily water changes at least 50% and monitoring ammonia. Is this ich or something else? I read today ich rarely affects the eyes. How can I help him quickly? Please help.
