These guys are probably favorite geckos. They are so big and beautiful compared with other species. I think mine is female because I don't see any pores when she is out climbing on the glass of the terrarium. I hope to breed her someday when I have the money to buy her nice big handsome fellow. You said you have never successfully bred Tokays? I think the key is the temp. and humidity. The humidity is important because they are from the tropic. Maybe your humidity level was too low.

Anyway, you have a lovely collection! Thanks for sharing your pictures!
