Ok, after reading old threads here and the article from U of FLA concerning "red spot disease," it appears that is indeed what my fish have. My question now is it beneficial to catch them and dip them in a salt bath or not? I have done so with probably 50 or so, but with water temps about 55 degrees, I wonder if I am doing more harm than good. I'm going to hold off on dipping anymore until I can get more info.
