Threats to the ecology: In my aquarium i wanted to show that this river is a very beautiful place. I think the bonito area is a very rare habittat of our fishes. The area is in a big danger because of deforestation. The landowners have no interest in this river so they do not care of it. So i would say that we can still fight for this beautiful place to save him for next generations.

Comments of the members of the jury of Biotope Aquarium Design Contest 2018

Although the design seems simple, the growth of vegetation forming these dense areas occurs naturally in many water bodies. With the driftwood covered with algae in the background and a bit of detritus on the sand it gives naturalness to the design. As a recommendation I would add more detritus distributed in the background. Good job!
