I've had this 7 year old (so the previous owner said) for over a month now. He was in an enclosed area which was big but he could of used a much bigger area. So now in my yard he has roughly 3000sqft to roam. Lots of grass, weeds, dirt and hiding spot. So just today I noticed his shell has a different shade all around. Almost like a ring. And it seems to look like new shell material I should say lol! I don't really know how to explain it so I attached pictures. Does this mean he's growing?? [emoji1376]
