Waterweed Exhibition 2013 at Tsukuba Botanical Garden

I have tropical fishes in my house. Since I like Bonsai and Japanese style garden, I'm interested in waterweed so much.
I went to see Waterweed Exhibition 2013 held at Tsukuba Botanical Garden.
 

I have a same size tank but I cannot imagine to make such a cool view.
 

When I look at it closely,  it seems rocky hill.
   

Nobody knows what's happened in the back. 

I tried to take photos with iPhone4S.  

Drastically photosynthesizing. Shrimps enjoy and play with oxygen.
   

Long way to somewhere in the forest.  

I really want to try to make "Terrarium" with Ishizuki bonsai...
   

Looks like a cave.
 

Field of perl grass and road covered glossostigma.


When I see someone's aquarium, I want to try something new with mime.
