World's Smallest Aquarium

Russian miniaturist Anatoly Konenko has been creating miniatures for thirty years now. He invented his own technology on writing on rice, poppy seeds, as well as human hair. He has recently created the world's smallest aquarium with live fish.

This tiny tank is made of fiberglass and there are living algae on the bottom. There is even real fish there, which size doesn't exceed 4 mm.
