thanks... My Torty is very little but almost of two years now.. N was born at my in laws place.. His mom was very old, and since his father was stolen she stopped eating n started laying unfertilized eggs, so we left her to wild with heavy heart.. As she was not eating.. Torty is perfectly fine...
by my research i can tell it is turning of shell into pyramid like crowns i can see some in your pic too.. Its sign of a disorder related to metabolism.. Meaning tortoise is not well fed.. However bit of crowning is fine.. But may be u need a check on your buddy's diet
