Zebra Danio Overfed or Pregnant?

[Danio8]

I just got 3 Zebra Danios a couple days ago and one looks like it might be pregnant but i'm not sure. I am not sure if it is male or female either. It is smaller than the other 2 with a more rounded belly. Can anyone give me their opinion?




I know the pictures are terrible. I can take better ones if needed.

Strong possibility that Danio is carrying eggs, of course the picture is a little blurry for my old eyes. I do hear that Danios are fairly easy to breed.
