Hi im looking into getting one of these animals and the only thing left is to try and get a female frog because the tank is in my room and i don't want to hear croaking and from what i have read the best and easiest sexing method is to check for nuptial pads so my question is are they just black pads like those of the African Clawed frog or are they different in appearance and if so please send a picture, thank you.

P.s I have looked on Google for pics but can't find any
