Although, this can happen when the fish realizes that her living condition is not suitable for a gestation period, and is also not the right environment to develop a fry.
Moreover, this states the reason why a fish keeper may find out a purchased molly fish is already found with pregnancy a few days after taking it home. Especially when there are no male mollies present in the same tank with it, or the female molly was not tested positive before purchasing her from the fish store.
