im on the phone with the breeder and he told me to stay away from the reptile carpet cause it is loaded with bacteria.. its hard to clean, you have to wait for it to dry out, exc... he said to just do a couple layers of newspaper or papertowels and to definetly close off some of the 55gal tank, he said its way to much room for them right now... he said it sounds like they are getting ready to shed, that stress usually shows in their beard not so much in the darker pigmentation on the belly.
