I really need help with my new hamster

[Coconutchrissy]

I have had a Syrian hamster before that was super sweet and lived for 2 years. and I have had a dwarf hamster that was very mean and only lived for a month I have gotten another Syrian hamster 3 weeks ago and he is 4 months old. When he is his cage, he will attack your finger! The bites are bad. When he is out the cage, he is a little afraid but will still bite. Is there a way to make him stop biting when he encounters things? And do you think he will always bite a hand every time you hold him? I am afraid he will not get better like my last hamster. Any toys that can help? I need any advice I can get, thank you!!!
