I'm not sure of his eating habits yet, hes a recent rescue. But he was definitely rearing and ready to go Saturday when I fed him. He struck the glass upon seeing the mouse outside of the tank and had it wrapped before my hand left the tank after dropping it in. I think he's going to prove to be quite a hog.. Hes a little underweight but overall healthy. I haven't seen any asfs in the pet shop, but I will look into it. He's about 4 months old and a few inches shy of 2ft, how old would the asfs be before they were too big for him to eat or will they get to big for him to eat and do they require any special housing needs or just the basic rat/mouse/hamster setup? Btw that's him as my avatar, about 5 inches of him was hanging off my hand.
