I have two leopard tortoises - one is just over a year old and the other around 4 months old. I've soaked them together, kind of like an introduction, and caught the older one sniffing the younger's arms/legs, and then going in for the chomp. The older one loves mazuri - is it possible he is just mistaking the little one's limbs as food? Or is he being aggressive in stating that this is "his turf and he is the boss"?
