Re: Your top 3 Substrate to use?
I like aspen a lot for corns, not balls. Humidity never seems manageable (at least in my tanks) with aspen.
I love, LOVE Eco Earth Coconut fiber. Nothing's better for holding humidity! If you feed F/T prey items can get a bit messy, covered in the fiber that is, but I've had no issue with it passing. If it seems to bug a sloppy eater, I stick em in another tank for feeding.
I will note that I will never use Repti-Bark again for a snake. My first little boy Sasha had a potentially deadly situation with Repti-Bark. Took the girlfriend and I over half an hour to slowly work out the piece that had become lodged over his throat during feeding. Scary, scary moment, never using Repti Bark again.
