I got my male sulcata over a year ago from a family that could not take care of him anymore. They said he was two years old when I got him. So he could be currently 3. But he is already a bit over 18 inches in length and I have seen sulcatas that are older than 3 years that are much smaller. I know that sulcatas grow at very different rates but I was wondering if my sulcata could possibly be older or is it very normal to be this big already?
