Reasons to attack and kill a stranger rat vary. It could've simply been territory, over the local area or even you.
Whenever you introduce a new animal, you need to get one to accept the other. Learned this from cats and dogs. I'd leave one in the cage and have the other one given free reign over the room for an hour, then swap one out of the cage, other in. Did this for ~12 hours.
This prevented them from fighting each other, at least the second they get with in proximity of each other.
Figured that letting each other "own" the same territory would acclimate them to the other's presence.
Perhaps rats require the same technique?
