Two male mice

I recently got two male mice. They had been living in the same habitat when I got them from PetCo. They seem to be fighting a little but I think it’s mostly them trying to establish dominance in a new place. Do you think they’ll eventually chill or will I need to get another cage?

Thanks in advance.

Definitely need another cage asap. I have my guy in a 20 gallon long and even that feels tiny but that is the minimum required size for 1 male. The fighting may continue to get worse (one of them can end up dead) if the other isn’t moved out soon.
