I got him from the Arizona Tortoise Compound so idk how he was started but I'd read a bunch of good reviews about them from on here before I even got him...and he's acting normal, plus I vaguely remember feeling it move a bit right after I got him but didn't think anything of it then, vut now with the humidifier I'm on HIGH alert for RI and soft shell/shell rotHe looks small for a five month old. You might have a problem there. A weight give give me a better clue.
Its all explained here, and I hope this is not the case with yours:
