I have had my baby sulcate for a little over 4 months. When I first bought (more like rescued) him from a pet store he was pretty small but already had some minor pyramiding (shown in the first two pictures at the pet store). If I remember correctly the pet store employees said their tortoises were around 3 or so months which would make my hatchling about 7 months old. He is still relatively small and is still the size of the palm of my hand. The areas in between his scoots show growth but he still seems so small. I feed him a varied diet of weeds and grasses with the occasional cucumber and carrots. I try my best to soak him in warm water once a day for about 30 min. I still see a bit of pyramiding trying to form and I just need some wise input. His enclosure is very well heated and humid also.
