When you visit an aquarium, you see different species of marine life in different 'sections.' They are usually surrounded by glass.
I want to build sentences like this:
I walked to another 'glass/section.' In it, I could see a many sting rays."
The shark whale swam from one corner of the 'glass/section' to the other.
There was a jellyfish in the middle of the glass. (OK, this one sounds weird).
I'm not very sure which is the best word to use here.
EDIT:
For example, this would be a 'section':
Is it right to say, for instance:
The people are looking through the glass.
or
There are many people in this section.
(I just need a general term that people would immediately understand. I need this for a novel I'm writing.)
