I recently caught 2 gray treefrogs near my house. They are only about 1 inch long. I found them on the ground which I thought was strange. I put them in their tank and they spend most of their time on the ground. They can't climb the glass walls of the tank at all. They stand on their back 2 feet and try to climb but they just can't. Are younger treefrogs more likely to be found on the ground than older treefrogs? Will they be able to climb the walls soon? Is it because I live in a drier climate that the frogs can't climb the walls? By the way I know they are gray treefrogs because they have the white spots under their eyes, and they are grey. malnutrition is not the answer either because they both eat well.
