I fully admit, I am not the best on sexing these guys, but that photo is not the best to really get a good view. For someone wanting to sell a frog, I would think he would take a better picture. And what is that white stuff in the middle set-up? It looks like a bunch of calcium powder got dumped-or mould......I would definitely get John's opinion on this one. He has given me plenty of sound advice and if he told me to go ahead and purchase a frog based on a photo, or use caution, I would listen to him. Best of luck!
