My molly now appears to have a hole under her and has a long stringy white thing hanging from her. The white thing has been there for about 2 days and is about 3 inches long. I have removed her and put her in to a one galoon tank with the old tanks water.Does Any body have an idea what is going on? the hole is like right before her back bottom fin (not her tail) I don't know the specific name but from the side it looks like it is indented at least an eigth of an inch. She used to have a white/silver patch there which I assumed was her coloring but and now wondering if it was something different. She doesn't swim much, just lays on the bottom. She eats only 1 flake of food when I feed her. But, She mostly just lays on the bottom of the tank. Please help my poor fish! :sad
