Hello... I have a couple questions... I have some lichen in my terrarium. Would this be a problem for dart frogs? I can remove it, if it will be. I put rocks in the fountain thing so the frogs couldn't accidentally drown. I think I am going to try to grow some plants in some of the rocks. This tank has a false bottom. I am still tinkering with the heat and need to put up a background... but if anyone has any suggestions, I would greatly appreciate them. Thanks!!!! Sorry if the picture thing doesn't work... Its my first time trying this : )
