I can't really tell from the pictures but is the UV source in with the bearded? Or seperated by glass? Needs to be in the tank with it, i read you took care of the temps and i'm not going to lecture you but i would SERIOUSLY consider ditching the sand and going with tiles or newspaper, or atleast place the veggie food bowl and water bowl on something solid so that neither the sand can get in or food can fall out, impaction kills incase you weren't already aware.
