On the other hand, dwarf Hamsters are less likely so territorial as Syrian Hamsters are. They can still live with each other.

Given that, Hamsters that are not so usual with sharing space or any other thing from childhood won’t share things when they are adults too. 

They are new to each other

When Hamsters are new to each other, it can lead both Hamsters to fight with each other. But the dwarf hamsters can get comfy once they are recognizable to each other.

They feel threatened

Often Hamsters fight with each other because they feel they are threatened. When any other Hamster tries to take away their space, they feel the other hamster is taking away their ownership from a certain place. So, to claim the area, they might often fight with each other.
