Well, he is about 12 inches but I don't know how much he weighs, I don't have a small enough scale. I've had him for maybe two years. I have no clue how old he is, since the pethope owner never told me. I just kept thinking he'd shed properly one day, but he really hasn't yet. His tail doesn't have any spikes, though which really worries me. It has the ridges, but I'm not sure if that is tail rot or his just bad shedding problem. It did shed once but it was a really thick layer. I live in the Upper Peninsula of Michigan and it is just starting to warm-up and the snow is just now starting to melt. I could only keep his tank about 90-95 degrees right now. In the summer, it gets a lot warmer. I feed him pellets and dried crickets (only ocassonly), snow peas, lettuce, apple, banana (which is his favorite), green beans, carrots, about three or four times a week. He has a heat lamp on the top, a heating floor pad thing, a log, and two rocks he can go under. There is that calcium sand lining the cage. (which he doesn't eat.) I give him reptile supplement maybe twice a month. (Is that enough?) And I put water in his cage about once a week. I haven't soaked him because of fear of tail rot and not being able to get the water from under his partly shedding skin. He is still really active, and loves to run around my house. He is just so cute! And he never bites me and he likes to be petted...oh, he's just such an awesome pet. I would hate if he was sick.
