Depending on howbig she was before, I'm going to say no. I have a pregnant silver mollie that is much fatter than that. She will have her fry when she looks like she's about to burst, and appears to be almost square when looking at her from the front or back.
I would say no, but then again, if she is early in the pregnancy she would not be that big. Wait a few days to see if she's just eating alot which could be the cause. If she seemingly gets bigger, than I would think that she's pregnant.
doesnt look preggers to me either, unless she's young and this is her first batch of fry she will be a lot lot lot bigger than that... but dont worry, if you have any males with her she'll be pregnant before long!
