I was just looking at my tank and I noticed that all of my angels have ich! My water is good, salinity is good, and the temperature is at 78. I also have a uv steralizer. What can I do tonight to keep my fish safe? I am going to the lfs tomorrow to get medicine but I'm worried about my fish right now. I doused their food with garlic and fed them. I heard that the garlic is good for them and prevents diseases. Is this true? I really don't want to lose any of my fish.
