Hardscape: Due to the fact that the river passes through the jungle there is a lot of driftwood and a lot of rotting organic matter on the bottom. As a result of this, the water becomes a black color stained with tannins. Along the river, there are bare rocks, large and small boulders, which I tried to mimic.

Driftwood: The roots of trees are similar to those found in the biotope.

Biotope description: The Atabapo River is a blackwater river tributary of the Orinoco River. The river is 131 kilometers long and gets up to 1 km wide. The depth of the river gets down to 15 meters. The water from the river mainly comes from rainfall. There are heaps of boulders and a dense forest on both sides of the river.
