Moss is good at holding moisture, but it's a major impaction risk. If you feed your toad in his habitat, take it out. I certainly advocate feeding in a separate container, as it removes the risk of impaction from substrate, and it allows you to monitor exactly how much he eats. I've heard of toadlets eating when they still had 50% of their tails, but more commonly it starts around 25% left. It's OK if the Eco Earth sticks to him. When he dries, it will fall off on its own. The soil really doesn't have to be all that moist as long as you are providing a water bowl to soak in. Keep it shallow, though, toads are poor swimmers and only need enough water to sit in and keep their head above water.
