I've got an adult Carrot Tail Leopard gecko and he's currently in a 15gal. tank with paper towels as a substrate.
I dislike solid substrates, even though they are simple and easy. I'm a fan of loose substrate, so I just bought some Coco Fiber for my tarantulas, Emperor scorpion, and my White's Tree frog.
I've seen people use Coco Fiber before. So since I just bought a new brick, I've come to ask if I can use this substrate for my Leo.
Thanks!
