All my hamster does is jump on the glass and try to escape and is not interested in me Why

I got a baby hamster 3 days ago, I think it's about 3 inches in length. I've been told everything about how to handle them, but I don't understand this one's behavior becuase I've never had a hamster. He is in a 10 gallon tank, with a wheel, cardboard toiletpaper rolles, a house, toys, and food and a thick layer of bedding. All he does is either run and run and run on the wheel or jump on the glass trying to escape. If I even slowly lower my hand into the tank he scurries the other direction or buries himself. Someone told me to hold my hand out with a treat and wait for him to walk onto it- I waited 30 minutes, and nothing happened and I had to stop because it was cutting off the circulation in my hand!! If I try to pet him myself, he rolls on his back, freezes, and bares his teeth. I did not handle him the first 24 hours, I have no idea what I am doing wrong. He is a male and by himself in the cage

Please buy a wire cage for your new hamster with a plastic bottom. It breaks my heart when I see them in glass cages, its so restricting for them. Hamsters need as much space as possible to feel free, to get exercise and to feel at home. The bigger the cage the better. This could well be your problem here, he does not sound a happy hamster.

I have had my syrian hamster a year. When I first got him he was very small. I brought him the basic starter home, plastic bottom, and plastic walls and lid. He hated it. It restricted him, and he would try to scamble and scratch his way up the sides of the plastic to escape and it broke my heart. He grew so fast as well, he doubled his size within weeks.
