The International Aquatic Plants Layout Contest, the world’s largest nature aquarium and aquatic plants layout competition, judges what has been dubbed 'aquascaping.' This term essentially refers to landscaping underwater. A rather unique undertaking, it is nevertheless relatively widely practiced, with top spots often won by aquarium designers hailing from Asian and Eastern European countries. With large amounts of biology, design and photography under their belts, it also takes a lot of patience to cultivate such scenes.
Colossal points out that submissions to the International Aquatic Plants Layout Contest can take months to create. Many of the underwater landscapes created could easily be passed for life-sized aboveground ones. In fact, it wouldn't be surprising if they were ever used for the movie industry, especially those that revolve around more fantastical story lines.
