It can only hold two teaspoons of water, it can sit in the palm of your hands, and there's only room for the smallest of fish in it - it's the world's smallest aquarium.

It might not be the most spacious environment - it's a far cry from, you know, the Amazon or the Atlantic Ocean - but the baby fish still have all the regular aquarium home comforts of multicolored stones, sand and seaweed.

Measuring just 30 x 24 x14mm, the 10ml glass tank was created by Russian artist and designer Anatoly Konenko – who still found space for a water filter.
