The worlds smallest aquarium

This tiny tank is made of fiberglass on the bottom rising living algae, and fish in it too, very real – 5 danio rerio juveniles, whose size does not exceed 4 mm.

Siberian craftsman Anatoly Konenko is responsible for the smallest aquarium in the world. A glass cube measuring 30 x 24 x 14 mm, filled with multicolor stones and sand, contains 10 ml of water for a tiny fish. It also have a little water purification filter to keep the water healthy for fish. Only baby fish can fit inside the tiny glass cube that is the world’s smallest aquarium.
