Hamster housed together

Question
I have a hamster named Chunky for like a year or so. then igot another hamster named hammy. I am trying to house them together but i need to know if it is gonna work cause if not i need to return Hammy. P.S Chunky and Hammy arent getting along well.

Answer
Nope, syrian hamsters can't live together past about 3 months of age. After that they start to get territorial and will fight another hamster for cage control. Unless you can get hammy in a separate cage, you really should return him. 2 hamsters left alone long enough can, and will kill each other.
