One of my whites tree frogs just ingested a small piece of bark while feeding. Now that my frogs have grown I am switching my substrate to eco earth only in the places in my vivarium not covered by live moss. This is the first time I noticed one of my frogs eating a piece of bark. What do I do? This only happened about 30 minutes ago. I have heard to keep them wet and in their water bowl. Any ideas other than watch for lack of appetite and not being able to dedicate and lethargy? How long should it take to pass?
