Found the receipt. I got him on the 11th actually. I feel like a complete idiot now, Ive been working overtime all month and my sense of time is completely messed up... you know, its probably only been no longer than two weeks since he's last eaten. He so readily took two hoppers when I first got him, but then I think he started going into shed. I still think housing him in a smaller tub is more secure for him, plus its what he's used to... he's just so tiny.
