What is a good substrate I can get at petco or petsmart or a mix I can make for growing plants? The retf enclosure is a 12"x 12"x18" exo terra. I'm going in to town tomorrow and i'm trying to figure out what I need. Do I need to buy some vines for my retf, or is live plants like pothos good enough? Can I use sphagnum moss to cover the substrate or is leaf litter better? What could i use to stop my fire bellied toads from dragging eco earth into their water? sphagnum moss, live moss, leaf litter or??
