[Gecko] Help with my fat tail

[Lisa woertz]

Hello all, great list. I just acqired a fat tail in pretty bad shape. Starving, thin and just a general mess. I had a few questions about my fat tail gecko. I have done some research on my particular gecko. As I am new to geckos in general. So, my question is what kind of substrate should I use? I have read thru most of the messages on this forum. And have heard conflicting responses. Just thought maybe one of the kind people on this list would be able to point me in the right direction. Right now..I have the tank set up with lizard litter. I'm wondering if I should be using something different. Such as maybe calci sand or cedar chips (maybe not called cedar chips) But noticed them at out local reptile store. Also, is moss a good idea. I know fat tails require alot of humidity. Thanks in advance for all your responses.
