Do Chinese dwarf hamsters kill each other?

Male Chinese dwarf hamsters can be mixed with others but if they begin to get aggressive with each other, separate them asap! female Chinese dwarf hamsters do not often like each other. it is best not to mix them as they will probebley end up killing each other. DO NOT MIX DIFFERNT BREEDS OF HAMSTERS eg. a syrain hamster with a Russian dwarf hamster. if you have just put the hamsters in one cage, keep an eye on them.
