Hello! I'm hoping to get some useful advice from those of you who have been aquarium enthusiasts for a while. About three weeks ago, my boyfriend and i were given a 35 gallon fish tank by a friend who wanted to upgrade to a larger tank. Although I know this now, we went about getting it set up and stocking it the wrong way. We had no idea what we were doing, so we just went for the cheapest fish. We have 10 goldfish (I know, way too many), 2 mollys, 2 platys, 3 guppies and a pleco. I KNOW this is a totally bad situation after having done some research, but we're stuck with it now so all i can do is try to make the best of it. The goldfish have ick and fin rot, and its spreading to the others. We've been rigorously treating, cleaning, changing water, and nothing is improving. Any advice would really be appreciated. We love our new tank and are really wanting to get into this as a serious hobby.
