Ah you see - hamsters are very intuitive and sensitive to emotions! He picked up that you were worried and probably read your mind

I'm only partly joking - hamsters can be very in tune with our emotions which is really lovely. He sounds absolutely great, and just like my cream banded Syrian! Active and out in the evenings. My other syrian is more of a shy lazy boy who doesn't come out much.
So you know he can use his water bottle now

How long have you had him? The first two weeks it's best not to disturb anything in the cage or clean anything, while they settle in and scent mark. Talk to him through the cage so he gets used to your presence and voice. It's also best to wait that two weeks before attempting to have him out of the cage for any taming/handling. Unless - he shows he wants to come out as some are more keen than others and sooner. If he comes to the door or shows like he wants to come out, you could try offering him a tube to walk into ( a rat tube or pringles tube is ideal) - providing you have a secure area set up to take him to. If it's in another room, then put the tube down in a box on the floor near the cage and carry him to the playpen or bathtub in the box. If you carry them too far in the tube at first, they push hard at your hands and it might make you jump and drop it.
I've just been doing bathtub playtime/taming with my young syrian recently

My other one (the one that looks a bit like yours) wanted to be out a lot almost straight away - but he was a few months old when I got him as a rescue.
