I have a 5+ year old sulcata. It's 19 pounds and 14 inches long. The carapace is flat and the tail seems short to ne. This one displays all the male activities very aggressively. Trys to mate the smaller 2. Gets right in the face of mr 90lb. female. I have a smaller sully half the size thar is for sure male with a longer tail, slight concave plastron and flashing bits. Could this one be trans?
