Does anyone know a way to tell? She has developed orange spots on her sides, neck, near her eye, and her whole tail (bottom) is orange. I've read on other websites that it's just during breeding season that they get orange and then it disappears after but I have another female that has no orange spots. Another website said that they develop the spots if they are bearing eggs. How can I tell if she's pregnant?

P.S. She has been eating a lot and I don't know if that could be a sign that she is pregnant.
