I got my two Aldabran tortoises as hatchlings in 2000. One of them was slightly bigger than the other and as he grew, he developed a "different" or funny-looking shape. I wasn't wise enough, at that time, to recognize that his funny shape was due to metabolic bone disease. I'm posting a picture of a picture of him that I recently found in my desk of when he was about a year old. You can plainly see the sloping carapace over the hips. This is a very good indicator of MBD. I only wish I knew enough at that time so I could have corrected it as it was happening. I'm having a heck of a time getting enough calcium into him now, at appx. 150lbs.
