It's not a big chain or anything, but the guy was telling me this bull crap story, of how if beardies weren't supposed to be on sand or walnut shell, they wouldn't be on the front of the sand. Also told me don't listen to the interenet their just speaking their opinions. Also i have no idea of this bulb i bought, i can't remember what it was called, i am going to check there today and see what it was called.
