I have a small fish that's similar to a guppy. I don't know what kind of fish it is since I bought her mother out of a gold fish tank, but it was not a gold fish. So, I have had it for a a year or two and she apparently has a HUGE chunk of fluffy Fungus on her back. Earlier, the huge chunk fell off because of it's size, but there's still more on her and her scales are red in that area. So, I went to Petco and got some medicine to put in the water. Do you happen to know anything about Fungus I should know to help my fish survive? 10 points for a decent answer. Thanks so much! <>< <>< <>< <>< <><.... .. .
