The Fishtank is an aquarium with a beautiful underwater environment of stones and roots, plants and a school of fish in it, of course, a pump, heater and light. The amazing thing is that the fish tank is nearly complete covert with black bitumen. You only have the possibility to see the inside through very small holes in the surface. It constitute the closeness between tradition and modernity, it play with the western ascendancies on the Chinese cultural characteristics, attracting curiosity and interests and ask questions about the environmental consciousness of our today society. „The Fishtank“ refers deeply to Bayers scientific background and is one of his main works of 2008.
