This is a picture of my little guy chomper. I changed his substrates from green carpet to top soil and sphagnum moss about a week ago. I hope this isn't pyramiding. And if it is, I hope I caught it in time before it gets worse
It is pyramiding. I wouldn't worry about it though. Just offer the best diet and conditions possible and you will have yourself a healthy tortoise. If all else is good, pyramiding is just cosmetic.
