Yes, as they will live in the same sort of water and temperature and do not usually attack each other.
no,your probably thinking about simese fighting fish. Answer- Mollies could fight if they wanted to. My mollies fight when they are intruding their partner. They will chase each other and nip each other. They don't kill each other. Don't separate if they chase each other. They are just showing who is the boss of the tank.
