Separate the hamsters. They do not live in groups in nature and only get together for a short time for mating. They are solitary animals and will continue to fight if they aren't separated. If antibiotics don't help, take them to the vet. Some infections can be below the skin where a topical antibiotic won't help. Only the vet can deal with this problem!
Another dwarf hamster.
probably because it it scared or trying to communicate with you or another hamster
Unless the dwarf hamster was in the same litter, I would advise against it. If they are not in the same litter, and you'd like to see if they get along, first put them in a neutral cage. Otherwise the hamster may feel that another male is trying to take over its territory.

no
there is no such thing but if you mean a roborovski hamster yes its a dwarf
It is best not to house your dwarf hamster with another hamster, especially the male species. They will bitterly attack each other. Both genders are not very friendly with other hamsters, and tend to be extremely territorial.
whats the latin name for a dwarf hamster
yes
Campbell's dwarf hamster was created in 1905.
It Depends On The Hamster Type. If Its A Dwarf Hamster, Its Better If Its Has Another Dwarf Hamster To Play With (make sure they are the same sex or you'll have little hamster babies ;P) If Its A Syrian Hamster It Doesn't Like Company, It Will Fight With The Other Hamster.Hope This Helps xD
There is lots like, Syrian, Chinese dwarf hamster, Campbells dwarf hamster, Robo dwarf hamster, Russian hamster. My favorite, is the blueberry campbells dwarf hamster and the Syrian hamster. They are the sweetest and easy to hold. NOT THE ROBO"S!!!
