Oh, I really had fun to realize this tank! First of all, I had a lot of space (150 X 85 X 60), second, this tank was right on the shop-window of my aquarium store, and is always exciting to create something stunning to hit the people!
I built up a wood bridge that kept the plants suspended to give a sense of underwater mystery (under the woods it was very dark, and all the people were looking to find who was living there!), but to give more brightness to the shop-window, I used white gravel, to give the appearance of a sand creek. I really have to thank Carmine and the other friends of the Tropical Fish plants breeding of Portici (NA), that gave me a huge help, producing a tiding up (one by one !) to the woods, their stunning Anubias and Microsporium!

Notes: The interior design of this tank, so beautiful when I realized it, was, after one year, destroyed by my 11 adult piranhas... That was calculated... Piranhas are great to capture the attention of the public, but very bad to live with plants! At the end of the year, I changed the tank, taking off part of the woods and adding pink-quarz rocks and white branches (and change the title to "In The Flood", referring not to the flood of the river but to the destructive attitude of my little fellows ! ).
