Tom,
I've had them for 2 years and was told they were 5 moths old when I got them. I have 2. This is the one with a more smooth shell. My other is show pyramiding which I dont understand because i got them together and they have alway been together. Initially started them out in a 20L glass aquarium,but they quicky outgrew that. They have been in various plastic Rubbermaid bins since. Humidity I try to keep at 75% and mist them and the Substrate(Coco) X3 daily. I use flipped over Akrobins as a humid hide. I drill hole on the top and then put a wet sponge over the top. Once measured humitdy in there as 83%. Diet is varied with low protein and no animal. I have never weighed them as I dont have a scale. I know they arent growing as fast as some people say their sulcata's grow but they seem to have a nice shape and I worry about overfeeding. Plan on lettiung them outside for the first time this summer. Tom, what are some thing that would allow the pyramiding to be much worst in one sulcata when they eat sleep and drink together? Never seen bullying so they have equal access to everything.
