Why is it you all want the largest of everything. You see something and want it with out even thing about how many are left in the wild. get a clue and a normal easily obtainable tortoise/turtle. they take years to grow and will outlive you. you will have to pass it down for generations and you dont even know if your kids or other family mebers or anybody elss for that matter will agree to keep an animal that size. Think about how big an enclosure you will need, how much food you will need, how to heat something that size up. etc. leave them for the wild before theres none left. ( dont care if its captive bred leave it you wont want it when your old and weak and its bigg and strong )
