Need help sexing my two African bullfrogs.

[FrogsRMe]

I have two pixies, My biggest I am almost certain it is a female, judging by it's "small" size lol.
My second I just bought a few days ago, still a baby. But I am hoping for a male..
Help please?

I only see one photo, and I can't really tell much from it.

Really? Do you mind telling me how you assume so? I can't tell because it's so young.
