My soft shell turtle has had for the last 5 days, fungus growing on her neck, nose, eyes and now stomach. I don't know what to do. Someone told me that means she's dying. Is this true? This soft shell turtle shares a tank (100 gallon) with 3 other turtles. A map turtle, painter, and mudd turtle. NOW, these turtles act weird as well. They are alway sleeping. They actually lay on the bottom of the tank in the corner with their eyes completely shut. I'm am getting nervous. Would it be something with the water? We feed them goldfish that didn't seem to healthy! Someone please get back to me and let me know what I should do. Thank you!
