Umm... there both boys right? I have one food hoppper, one water bottle, and one wheel, and one hide for the both of them. And they have never "fought" as in actually fighting for real. They rough and tumble play, and can get vocal sometimes, but in my experience, they never had trouble with just one of everything.

Usually boys will only fight when the scent of a female is really close, or the female is present. Then they can fight to the death. But if thats not the case, then i think your fine. Just make sure they have enough space to stay happy and healthy.
