Two hatchling Aldabran tortoises came to live with me in 2000. I made mistakes with them, and they're not perfect specimens, but they're coming along. Besides the bumpy shells, you'll notice a scoop over what would be the hip area. This shows a calcium deficiency or MBD. The last time I weighed SO, two years ago, he weighed 180lbs. He's much bigger than that now, but we can't pick him up to weigh him. I give both of the Aldabran tortoises extra calcium daily, inserted into a piece of fruit and stuck on the end of a skewer. After three years, I'm starting to see an improvement. The bumps will never smooth out, but the MBD is slowly going away.
