Oh yes. They started that at about 2 years old. I posted pics here somewhere. They are maniacs all the time. They remind me of those occasional "super" Testudo that you see. You know those bold crazy little Greeks or Russians that just run up and challenge, ram or bite everyone and everything. These guys are all like that. I had to separate Mr. Irregular scutes (Originally "Big Momma, and later re-named "Big Daddy") out of the group because he was even worse than the others. I want to let the females grow in peace and get some size before I let the males have at them. Eventually they will live in 1.2 or 1.3 groups. I've got a total of 6 females.From the scuffs on the carapaces, looks like your males have reached sexual maturity. Lots of practicing going on.
