How Do You Tell If Bolivian Rams Have Paired Up?

[sbga]

I have 3 Bolivian Rams in a 46 gallon tank, just got them today, hoping to get a pair and give the odd one to my Grandmother's tank. So far there are 2 that almost always end up sticking together, while the other one is mostly to himself, and sometimes tries to fight the other two. However he will sometimes become friendly and swim with the others. They have only been in the tank for 3 hours so far. Should I wait longer or is it pretty safe to say those 2 are a pair?

If the 2 pair up and fight off the lonely one then you know you have a pair. It can take a few weeks for them to fall in love. But when they do you will know.
