fin rot on goldfish
Hi, I am new to this forum and to goldfish. My family recently set up a ten gallon aquarium with a bio wheel for filtration. We put a fantail in which almost immediatly contracted fin rot. I have treated with meds. Although I am only on day 2 of treatment, he just seems to be getting worse. If we are not able to save him, will this disease still live on in our tank? Do I have to worry about putting something else in it? Thanks for any help you can give me.
