it doesn't matter prepared or not for breeding, pacman males have nuptial pads all year. if they're sick/malnourished then sometimes these pads might loose their coloration but will still be there. other species of frogs will develops nuptial pads only during breeding season, that is not the case of Ceratophrys frogs.

if you don't see these - you have a female, if you want to confirm what you think you see, just post pics of thumb, similar like the ones Grif and danfrog posted, we'll help you out with that.
