So, in my eagerness to get my vivarium finished I threw all of the substrate, and plants in before siliconing my driftwood to the back glass to keep my frogs from getting behind it all- it's just stacked up. My frogs like to hide behind it during the day, and i'm worried that over time they're going to make a mess back there....
When the weather clears up I'm going to move the frogs to another tank, and work on cutting all the wood in half then silicone it to the back so it sits flush with the glass.
Should I worry about making sure the frogs can't get behind the wood? Do frogs defaecate where they sleep? Are frog feces relatively sterile- especially when it's old, and dried up?
