Introducing new breeding groups

Hey everyone,

I hear a lot of people say they have never been able to introduce adults back together once they have been separated...without a battle royale at least. I have successfully reintroduced 2 breeding groups after 2+ months of separation. Just wanted to see if anyone has as much luck, and if you think whether or not they are related, same size, etc has any effect on the results. So far, they have been the same size and from either the same litter, or a litter from the same nest.

Wow I am bored...sorry for the someone worthless post.
