Keeping two male mice

[Beardedragon]

I saw that someone post keeping 2.15 mice ratio in a single tank, I was wondering if i could do that? I know males will fight, but what if theres plenty of room to share?

In my experience no, unless they were raised together from youngsters. When I've tried to put two adult males together, More often then not they will attempt to castrate each other with their teeth.
