Many people do find pairs of dwarf hamsters need separating. A Robo breeder thinks they are a species who do like company and to live in pairs or trios. And as Souffle says they are the species most likely to do ok. It does need a lot of careful setting up to try and ensure they don’t fall out. Two or three of everything - wheels, houses with more than one entrance, water bottles. Better to scatter feed rather than bowls. No levels in the cage- that encourages territorial behaviour. Cage not too big not too small. Some people even say that taking them out of the cage separately even for a few minutes can cause one to become territorial about the cage so they need to be taken out at the same time.

As mentioned above you’d need to have a spare cage and be prepared to separate them if they start to fall out or one seems to be dominant and larger and the other one is a bit small.

There are people who have successfully kept a pair for life but it isn’t that common. I was going to adopt a pair of robos from a rescue before we got Moo - but they had to be separated before they were adopted - and Moo needed a home more than one of the robos.

If you want to get both and can put some effort into a careful set up then you could try it but you would need a spare cage in case they needed separating in a hurry.
