Is it possible for two male syrian hamsters, not from the same litter, to get along?

I have two hamsters, The first one I bought maybe 2 weeks ago. He was very lethargic, so we thought he was lonely. So we bought another hamster, who is maybe a month younger than the first. The second hamster is suprisingly more aggresive than the first.. but is mean to everyone and snaps at anyone who comes near... I feel like I've tried everything! HELP!
