About two weeks ago I noticed some of my pond goldfish and shubunkins with a fuzzy fungus type of problem. I bought some fish treatment and treated the whole pond. I didn’t notice any improvement, so I set up a fish tank in the house with some of the medicated pond water and added some salt. I caught one of the sick fish and brought him in, and I don’t see much of a difference in the tank, either. I was finally able to catch another sick fish after two days ago and put him in the fishtank, too. He died after two days. So now I have to wonder if the sick fish are better off in the pond or in the fishtank.
