Ok so I'm going to give it a shot:

What I see is the metaphor of the city as a fish bowl. People are entrapped there either by their own doing or otherwise and are unable to escape into the great big world around them, represented by the ocean. The pedestal symbolises the fact that we place living in stucco-walled condos up on a pedestal while it is less than ideal and separates us from nature and the rest of the world as well as creates an impractical and unnatural goal. Clearly, the goal of the fish is to be outside of its bowl and in the ocean as it should be the goal of the city's inhabitants to be outside their artificial 500 sq ft flats and on the beach.
