Please HELP I think my mice are fighting!

I've had one female mouse as a pet for a couple months, and then I learned that it would be better for her to have a friend to play with. So yesterday I went and bought another female. They were okay at first but then the older one started biting or nipping the little one and chasing her, and the little one starts squeaking loudly. I'm not sure if the bigger one is actually hurting the little one or not, but she's never drawn blood and it doesn't usually go on for more than 10 seconds at a time. They do eat together but they don't sleep together. I'm also not sure if the big one won't let the little one sleep in the nest or she doesn't want to.

Are these just little arguments? Is it a dominance thing? Or should I definitely separate them?

I also have the opportunity to get another female that's the same age as the younger one and almost the same size as the older one? Should I introduce this one in hopes of stopping the behavior of my mice? Or would that just add to the tension?

This is my first time owning mice so any advice would be MUCH appreciated!!!

I don't think I can help you but maby you should just give it some time. I had some mice and just got a new one and the new mouse got picked on but it took a few days before they were nice to each other.

As long as there is no blood or missing fur everything is OK. If you see bites or blood open sore then you have to put one of them in a cage of her own. Normally females get along OK together.

as long as they don't bite eachother and blood is drawn they will be just fine. they are probably playing or something, otherwise seperate them permenantly.

definitely separate them and introduce them on neutral territory, if the older one keeps biting it you have to separate them indefinitely. adding another will just stress the old one out more

I would separate them and get nice that are the same gender and try that or have then in separate tanks just have them right next to each other so thay are able to see each other but not fight that is what I would do(:E
