This is Joey, he's a African spur-thighed tortise, I got him in 2000,when he was the size of a half dollar. He's about 75lbs right now.He roams our backyard, consuming about anything... including dog poo. (we try to discourage this behavior, though) He used to live in an aquarium, and at one point he had free roam of the house. (before his poops became horse-sized).Full grown size for him can range from 75-150lbs. That happens by about age 15, so we just have to wait and see..(hopefully dog poo doesn't stunt growth!) He will live up to 150 years, so it's a good thing we have kids. He will be quite an inheratince one day.
