So I have a pair of winter whites that I seperated because their behaviors seemed to turn from playing to fighting - one would constantly chase the other and they would not sleep or eat together anymore. One hamster would steal all the food in the bowl and hoard it.

I seperated the cage with one of the glass detolf shelves in the middle, but since there's a small crack between the wall and the glass shelf, they keep sniffing through the crack and trying to go through; however, if their hands or noses touch through the crack, they will squeak like they are fighting again. What should I do?
