Sometimes 2 boys will get along but it is a bit unusual. Even though they are neutered, bunnies are still very territorial. They want to be the boss, they want the best food and the best sleeping and best hiding places. Make no mistake, withoutm having them neutered they probably would have ended up really hurting each other badly (at a minimum).

Rabbits tend to be social animals and prefer to live with other bunnies. OIt's unusual but once in a while you'll find a bunny who really wants to live alone or, as I like to say, be an only child.

In any pair or group, they also have to sort out who is going to be the boss. If you have two strong-willed rabbits both wanting to be boss you have got a real problem. If you have one who wants to be boss and the other tends to be laid back, or if you have 2 laid back buns, then you are ok. This is the same for females. Ideally the very best pairing and the easiest pairing of 2 rabbits is male to female.

I think if I were you I'd keep a close eye on them for the next several weeks and monitor them closely. Be sure one really isn't bullying the other.
