Silly question about pet mice?

it could go both ways with mice, siblings generally do better when getting along with eachother because the younger you introduce rodents the more likely they will bond, mice are social animals so a pair is more ideal. I think that was long as the cage provides enough space from each other and at least two hides, the brothers should be fine together, as long as you dont wait to long to reintroduce and never indroduce a female, even if the female is in a seperate cage. but at the same time ir you dn't want 2 mice as long as you gave the boy planty of attention he should be fine alone. If they were females ild say defently take a sibling because they are alot more social, but with males its a hit and miss.
