It has been my experience that arboreal frogs do not do well in a tank that has little to no ventilation. They just slowly waste away. I have red-eyes, a frog that needs some decent humidity, but the tanks have to be venitlated or they die. So I mist them once a day, making sure the substrate is moist. They also have a large water bowl to bathe in and they do fine.

The first picture makes me think that it an orientalis. The second one two, but less sure of it.
