hi there! this is my first post. i have 2 american toadlets that have just morphed their front legs .. one of them is a day further along than the other and has started venturing out of the water. but! he seems to like to climb the sides of the tank. i have a lid on it, but i'm afraid that, being so tiny, he'll get squished between the lid and tank or because he's not totally landbound yet, dry out or something awful. can anyone recommend anything to keep him from getting too high up the wall? thanks in advance!
