Rio Tapajos
This was the first home of the piranhas I was talking earlier. Knowing that being a fast grower, this fish will sooner or later live without plants, I took advantage of the small size of the babies to create a real forest, trying to duplicate the wild aspect of their home-waters.

Notes: I still like very much the strange mix of plants and woods of this tank, it's disharmonic but fascinating, and the interior design was studied to give the feeling of a flooded underwood.
