I use Fluker's All Natural Moss for all terrariums, it's green but not live and available at PetSmart. I haven't had any trouble with it in the very long time I've been using it. I started using it with my FBTs and now with all of my frogs. IDK about other mosses and leaf litter as I have never used them. My gray tree frog loves to get under the moss when he's in a hiding mood.
