the green vine snakes, yes they pretty much hafta eat lizards....but i was also told that crickets and pinkies are ok too....but we got some anoles for him which he really liked.
as for the skinny part- yes he does seem a bit skinny atm but we put in a bunch of crickets in the tank and hes been chowing down. I really hope that he doesn't have parasites. Is there something we can do about it or do we need to find a vet
