Prestondactylus,
I don't take kindly to being called blind, you should choose your insults more kindly when speaking to people. There is no physical evidence that has been presented to any of us regarding a true breeding of these two species. I don't believe it. Cresteds are bred specifically for the "fur" trait, as well as a "no fur" trait. This crested does not have the crests (although they are on the eye-lids), but there are many with no crests on the market. These are one of the most reproduced geckos in the market now and strange individuals show up all the time. This looks like a normal crested, with no spines. Even the tail is white, a characteristic of A LOT of cresteds. What differences physically do you see with this animal and a normal crested, other than the lack of spines? I think there would be a much higher chance of success breeding crested x sarasinorum, but chahoua seems a bit out of the question. Leland
