I have my 3 1/2 month old 1.0 normal in an 18 gal hex tank. I originally put him in there because he loved to climb so i gave him the height to do just that. But after a while i started hearing these weird noises. realized it was him falling from the top of the tank to the ground then getting up and doing it again!

So i took the reptile hammock from my beardie's tank and put it in his. Now he falls on that instead.
