9 Month old Male rat

Monty is a 9 month old male rat that i unfortunately have to rehome due to him not getting along with my older rat. Monty is friendly however he is a nervous little guy and does bite, he does not like to be held and he does bite unless trust is earned!! Which is why i want Monty to go to someone that preferably has owned rats before and is willing to be patient with him and earn his trust. I’m not sure how he would get along with other rats but i think he would be completely fine on his own like he has been for the past couple weeks as i had to separate him. He is not neutered.
