OK, I read about Springs Disease and looking back now, it seems he may have had that. He did yawn a lot, and slept on the ground a lot but I didn't know that was bad. And I didn't clean the plants themselves but I did shake the dirt out. How can I thoroughly clean them for when I bring the next froggy (from the petshop) in? Also we misted his terrarium once a day and had a night heating lamp.
