she looks quite well sqared off at the bottom so i would say she is pregnant she also has a shaded patch around the rear which could be the eyes of the baby fish its a bit hard to tell but seeing as she is so square to what they usually are (very round not square bottomed ) i would say yes she is and due soon maybe in the next week
thanks wont feed them tomorrow but i dont think shes a greedy fish as she eats about the same as my other mollies but will take you up on that thanks again
