I've let the moss take hold before putting the toads in, plus they have plenty of places to hide so they haven't dug in any spots.... yet. I've only had them for a few months and they use the water dish for the toilet most of the time, which I change 3 times a day. I've layered rocks, organic soil, coco fiber then the moss. Nothing is molding or smelling funky and there are lots of new plants sprouting in the tank. It also has great ventilation so at this point I'll leave it alone. I also got the tank from Petco on sale for $40.00, I couldn't refuse.
