Rabbits Wondering If Lops and Rexs Get Along?

So i now know that i have a mini rex thanks to all your help. So now that i know what he is I'm thinking about getting him a friend. I'm really wanting a lop, So i need to know if these two breeds will get along and since he's a boy should i get a girl and get them both fixed? Or will two boys get along? I've heard story's of how boy rabbits don't get along, so i just want to make sure.

Thanks for all your help.
