Housing a pair of dwarf hamsters

[Little Nugget]

Hi! I already own one Syrian hamster, but I am looking to get another or possibly two. I most likely want to get a dwarf or pair of dwarfs and I would get a female(s). They would be Russian cambell dwarfs. Is it ok to house them together, or would they prefer to be housed alone? I know that this is a debated topic, but I wanted some insight from other hamster owners. If you’ve housed dwarfs in pairs before or currently do, that would be very helpful. Please share your opinions and experiences. I am aware they will need a large cage (I’m probably getting a 40 gallon reguradless of whether I get one or two) and also two of everything so that the risk of fighting is reduced. Just was wondering if you guys would recommend it, or if they would be more happy living alone. Thanks!
