I doubt the aquarium will have as many sharks as portrayed in the picture, if that's causing you to be alarmed, since the tank seems not big enough to accommodate that many, or that size. There would probably not even be one shark of the size portrayed in the picure. Also, the glass isn't flat, but part of a larger, curved, fish tank, which isn't likely to break.

I agree. It might be the fact that in the picture the tank looks close to the ground,maybe that's why it seems alarming. Or maybe its because people are eating and the sight of a shark in your view while eating is bout to make you feel nervous and alarmed.
5 deaths per year are from shark attacks. Why so serious?
