I created this layout while imagining the downstream of the aqua terrarium that was published in the previous issue (https://www.adana.co.jp/en/aquajournal/nature-in-the-glass-aj303/). Using Sansui Stone in the same way as in the “upstream” aqua terrarium part, stones were placed with consideration for orientation, size, and shade, and arranged in a rhythmic manner to express the natural flow of water. The bright green of Ottelia ulvifolia not only softens the impression of the shade of the Oyaishi (the main stone), but also gives viewers a sense of water flow when viewed from above the water. In addition, Eriocaulon sp. ‘Social Feather Duster’ is planted to create an underwater feeling, and its planting space is gradually narrowed from right to left. I believe that I was able to express the story of the water cycle in the natural environment through a series of scenes composed with the aqua terrarium featured in the previous journal and this Nature Aquarium layout.
