No, aquariums really aren't suitable. The main problem as previously mentioned is the lack of ventilation. Hedgies have very sensitive noses and an aquarium does not allow for air flow to keep the smell of their waste away from them. This is not to say they have a strong smell for the most part but their nose is only inches away from their waste.
Also for an aquarium to be large enough to properly house a hedgie, it becomes harder to clean due to it's weight.
A suitable alternative is a C&C or Sterlite container. With the Sterlite container you're able to drill holes for ventilation and can easily haul it around for through cleaning.
Also with the cage being so close to the window, I'd be wary of drafts.
