I agree with Wellington. That is tortoise aggression.Hi my horse field is 3 years old if I lay my hand flat on his substrate he bob's his head furiously then moves towards it , my question is, is it a friendly motion or an aggressive one
"RUSSIAN" Tortoises can be fiercely territorial.It's only a matter of knowing my tort not so much of a concern, obviously I'm not concerned per say just keen to understand what he is feeling thanks 👍
