OK, I have a small female motoro, 6" disk. I have a few german rams in there with her. One of the rams broke out in ick and I was told not to put ick meds in there with the ray. Heat and salt is what i was told but how much salt is too much? I'd obviously rather save the ray but I like the rams as well, I don't have another tank to put the ram in to treat it. What do I do?
