Looks like a male to me as well, though the photo is taken under a strange angle. Could you post a photo of the whole gecko on its profile side, and another of the belly and tail base just to confirm sexing? I think I can see bulges on yours, but I'm saying male only with 80% accuracy.
I am currently looking for keyserlingii, may I ask where you are from and where you get yours from? You can reply through a private message if you don't want to make it appear on the forum. I shall be grateful. Thanks!
