I wouldn’t recommend trying to keep any species as a pair, all species are solitary really & it’s very rare for any pair not to fall out & fight as they mature & need their own space. Half a detolf isn’t really enough space for one ham & even with a divider of some sort the hams would still be aware of each other & each others scent which, after falling out would be stressful for them
Trying to keep hamsters in pairs is stressful for the owner, having to constantly watch for signs of falling out & very stressful for the hams to which impacts on their long term health.
Better to just have one healthy happy ham.
