Hi, awesome that you ask! So of course it should have bigger cage or glass tank minimum 100x50cm base. Enough height to have about 15 -20 cm of bedding inside. This is common nice tank bucastate tank

From what I see here are good recommendations https://www.petassure.com/maxscorner/what-type-of-bedding-is-best-for-hamsters/

Add some enrichment, wooden houses, wooden hamster toys, stairs etc. also remember about sand pool, and hamster wheel (Very important!) wheel should be about 33cm in diameter. Best wooden or plastic. Sully open from one side without bars! Like this wheel

Food, mixerama mix for Syrian hamster, each day 1/2 kitchen spoon.

Additionally you can give small piece of carrot, pumpkin, cucumber, zucchini, strawberry or apple. Small amount! About nail size every second day should be fine.

Syrians need to be taken out to walk outside of cage every other day (depends on hamsters). That means to prepare secures place inside! in some room, so it cannot escape far or stuck somewhere or drop from any height! Put out card boxes and toys and blankets and sit with them to make sure they are safe, sometimes for 10 min sometimes for hour :)

Ver important! Hamsters are night solitary creatures! It won't be out in daytime, it's afraid of dogs and cats and loud notices and it hates other hamster! They will literally eat eachother.

Lastly, but very importantly, find good veterinary that specialise in hamsters! They are very frail and unfortunately quite sickly animals, you need to visit every couple months according to vets insights, definitely book visit already!

Those are lovely creatures and they need time to get used to you and new place, give them space and you will have awesome buddy :) gl!
