Sapphire is probably 20 years at least. But he's only around 5 or so inches long and wide. He hasn't grown since I got him but his shell did heal. He was maybe 4 or 5 years and wasn't in good shape. I decided not to send him back and demand my money back just take my chances in the hopes I could help the poor little one. That was May 2007. I wish I could have found TFO then. I could have helped him more sooner.how big is he?
