P. sauvagii need help with sexing-picture

[Monkey Business]

Finally I got a pic-at least a link-loaded here. My frogs decided to “cuddle” (LOL!!) for Valentine’s Day.

I am trying to figure out the gender of my frogs. I have seen nuptial pads for sure on three; not on the fourth yet, which I am hopeful is a female. I THINK that is the bottom frog, the only way I can really tell them apart is when I weigh and look at them.

I know it is not definitive, but I hope you guys can give me your opinion on the sex of these two.
