Seems as if my 3in body goldfish has ich, sits at the bottom every now and then, but today it's because the water is freaky cold since it snowed 2ft out. I have plants, so I can't add too much salt. I have Dojo Loaches, but the Quickcure isnt a prob to them, what about salt? I have 3 filters, a total of 220 gallons. I have a heater, but it's broken and sorta works, so no option to raise temps. I got rid of two 4.5in common goldfish a week ago to reduce ammonia stress and add space. It's a 55g tank with sand, up for 6mo+ and I do 10Gal water change every day. Used to do 30Gal when I had the other 2 goldfish in there. 0.0.8 tests
