I am trying to decide on whether to buy an African Fat Tail Gecko or a Leopared Gecko. I like the sound of the AFT's temperment...ideally I want a gecko that is calm and easy to handle. Also, when it comes to substrate with the AFTs, is it the same with Leos in the sense that you should use tile or paper towels, or is Eco Earth a possibility too? If just tile, would a humid hide be fine for humidity?
