COnsidering that Chacoan Horned Frogs come from the Chaco region, I have always fancied the idea of using a clay substrate. I was wondering if anyone knows any materials, such as red art clays, bentonite, soil and clay mixes, or something such as that which may work as a moist material that the frogs can burrow in.
I guess my main concern is moisture retention, so Ive considered a soil clay blend.
Right now I use moss for my pacman frogs, I dont use coco fiber because it gets the frogs so dirty.
