Russian tortoise behavior?

Question

i posted a question about this yesterday and i got some answers from people that say my torts behavior isnt agression, but i completely disagree. heres the situation: i just bought another russian tort. my old one has always been unfriendly and it hisses and rams the new one. when i go to pet the old one it hisses and tries to ram me as well. why is it so agressive towards everyone?

and for other russian tort owners does yours act like this at all?

Answer 1

i owned one and kept it in a cage with a box turtle and they got along great ///

Answer 2

you need to separate the two tortoises, are you sure they are not both male, tortoises are very territorial and males should not be housed together as they will fight often to the death, your tortoise is upset at the invasion  by the other tortoise it See's in its territory, this aggression will spill over to you separate the two and you will see the difference

Answer 3

ours is a female and she is friendly

are you sure that you don't have 2 males?  if you have 2 males you must separate them or they will fight all the time
