@pachyderm pro It kind of reminds me of Berlin's otter exhibit. It seems quite strange, until one realizes that they are trying to preserve this cage. (For some reason).
I definitely did not see any Fishing Cats in this interesting exhibit, and I think that it would be quite a stretch to lean over and be able to touch the glass.
Here is a video of a cat using the underwater viewing to catch a fish. As you can see from people's faces reflected in the main window, glare is a problem with this design.
