今までも水槽に１００円均一で買ってきたガジュマルを入れていたわけですが、この間ガジュマルの根っこが２マタの大根みたいになっていてそこに水槽のガラスをはさめば手入れの要らない天然浄化装置になるんじゃないか？と思ったのでやってみることにしたんです。
やってみると何かいい感じ。
これを沢山つけてゆけばおもしろい水槽になると思いました。金魚がいつまで生きてくれるかわからないけど、夏の暑さ対策にもなるのかもしれません。
水槽全体を見てみるとこんな感じです。ガジュマルはもうひとつ投入してあります。どっちもこの間まで枯れていたのだけど、こいつらの生命力は半端じゃないので枯れたと思っても捨てないでそっとして置いてください。落葉樹なのだろうか？いやそうでは無いと思うのだけれど･･･
最終的には、ミニチュアマングローブのようになったらおもしろいなぁと思っています。まぁ、実験に過ぎないのだけれど。

Banyan (genus: Ficus subgenus: Urostigma) is a subgenus of many species of tropical figs with an unusual growth habit. They are large trees that usually start life as a seedling epiphytic on another tree (or on structures like buildings and bridges), where a fig-eating bird has deposited the seed. The roots descend over the trunk of the host seeking out the soil below, once they have rooted into this the fig roots rapidly thicken and lignify. Where the fig roots cross each other they fuse, thus creating a lattice around the host tree's trunk. The fig competes with its host for light, water and nutrients, while its roots prevent the host's trunk from growing. Eventually the host dies and rots away, leaving the fig self supporting as an ordinary tree, but with a tubular lattice of lignified roots instead of a trunk. For this reason banyans are often referred to as strangler figs.
Banyan Tree at Melbourne Botanical GardensAnother unusual feature of the banyan is its ability to produce adventitious roots from the branches. This characteristic of developing aerial roots allows a single tree to spread over a large area. The biggest banyan tree in Pune, India is said to measure 800 m around its perimeter. Another famous banyan tree was planted in 1873 in Lahaina's Courthouse Square in Hawai'i, and has grown to now cover two-thirds of an acre. The single largest unity of Banyan tree in the world is in Howrah (West Bengal) in Botanical Gardens with a width of 420m.Like other members of this genus (which includes the common edible fig Ficus carica), banyans have a unique fruit and insect mediated fertilization process; see Fig for details.
Ficus retusa, also known as Ficus Microcarpa Nitida, Banyan Fig, Taiwan Ficus, Ginseng Ficus, or Indian Laurel Fig, is a species of evergreen woody plant in the fig genus, native to Malaysia, Taiwan, and other Southeast and East Asian countries. The tree has small, dark green leaves which alternate up the stem and which are oval. It has a gray to reddish bark dotted with small, horizontal flecks. It is considered one of the easiest trees to keep as a Bonsai.
