>>So I'm reading a lot of threads pertaining to substrate, and it seems like everyone has something negative to say about this certain substrate or that certain substrate. Is there at least one substrate mostly everyone can agree upon that is safe for snakes AND looks nice?
Use something that you will enjoy looking at and feel confortable with. There's nothing out there that is 100% safe, if a snake swallows large amounts of, it could be fine, or it could have problems. There are neg. and pos. thoughts on everything. Just be careful when feeding, that the snake doesn't injest large amount of substrate while feeding. I've had between 10- 25 snake on 2/12 kiln dried sand for the last 14 years without any problems what so ever. All my subjects are heathy and active.
Good luck, and Enjoy your reptile; Bob
