I've been following ths thread and am concerned because i just noticed a "cottony" spot on my Fancy Goldfish, too and today it has little specks so it is definately ick. My pet store gave me a product called Aquari-Sol- have you heard of it? My other Fancy has no spots (yet) so I think I am catching it right at the beginning. My tank is new- I have had the fishies 5 days and really don't want them to die! They are both eating well and are active- my question is.. can I use Aquarium salt and the Aquari-Sol? Will the salt interfere with the medication? I am going to remove the tank decorations tonight and do a partial water change and vacuum then I'll put the heater in and stat rasining the temperature..
