Hi Ajax.. thanks for comment...
The background is a self-made product... I love to searching natural materials and to use them for creating something inside the tank....
This time I have tried with a background that reproduces an african river side...
I have pasted natural materials like leaves of poplar, stones, several sands, pieces of screw root and dry grass with polyurethane foam.
I could add other moss on the background in the future, thanks
