I see almost no tail, or a very small one
Russian is male no doubt. Sulcata is too young I think.
Wow, do you in-laws really like you? They may have given you a growing ruffian/bulldozer!okay thanks! The sulcata is 2 years old, just got it from my in-laws. Definitely not a fan of being held, unlike my Russian who will completely come out of the shell when held. The sulcata actually peed as I was taking the photo
