r they housed together ?? r they both males? well they might have had lack of sibling interacting as babies. meaning they were seperated to young of age. Dwarfs are very social also they are very speedy and hyper. Syrians are more layed back as they get older. Be patient they are in a new home and crud they will get used to being handled soon, I am used to hamster bits now that i have had 2 litters of pups lol ..
