I got to adult Green treefrogs yesterday and set them up in a 10 gallon aquarium. Though it is not vertical, there is still a fair amount of height, and I put in lots of silk plants, baked wood from a local lake, a large water dish, a layer of moss for humidity and a heat lamp set over the middle of the tank as our house is getting rather cool now that it is fall. On a good news, we are pretty certain that we heard calling, confirming suspicions that one is a boy. However, when I got up this morning, both frogs had buried themselves into the moss. I had misted heavily last night in the hopes one would sing, so I can't see humidity being a problem. I did shut the lamp off-could they have been cold? Obviously I am not meeting one of their requirements, but I can figure out what. Any ideas? Below is several pics of their setup.
