Flooded forest in the El Tuparro National Park, Rio Orinoco
Colombia, Dipartimento di Vichada, Puerto Carreño
The El Tuparro National Park is the biggest river catchment area to west of Rio Orinoco. The biggest part of it consist of flooded/non flooded savannas and as we head closer to the main stream the fooded forests are more typical.
The habitat that I want to introduce is next to the borderline of Venezuela and Colombia near Isla Santa Isabel. It is a flooded forest biotope, circa 200m far from the main branch of the Rio Orinoco.
I found a video from the 1990’s, which tourned out to be my greatest motivitation to create my biotope aquarium. In this habitat several fish species can be found like Paracheirodon axelrodi, Axelrodia riesei, Hemigrammus rubrostriatus. And some cichlid species too, such as Dicrossus filamentosus and Aequidens metae. Specific submerged plant e.g. Najas guadalupensis. The substrate is not too visible because of the leaf litter, algae and mass of bacteria.
This palm tree Mauritia flexuosa is very important to the native warao indians.

- Surrounding area
In the surrounding area there are more flooded forests with slow moving water and to west you can find the main stream of Caño Guio.
- Underwater landscape
The landscape cosist of white silica sand, but it isn’t too visible because everything is hidden by fallen leaf, algae and mass of bacteria. There are several branches in the bottom and scatteredly some root systems too. On the edge of stream bed you can find lots of submerged trees, palms and bushes.

Comment by the expert
Roberto E. Reis: Fair research on the Rio orinoco in Colombia, with many fish species included.
Flavio Lima: Considering that a good reference for reconstructing a aquatic biotope is aquatic footage from the biotope, I think that the participant has used an appropriate source. No other sources were cited but in fact references for aquatic habitats in that region are sparse in the literature. One mistake was the inclusion of Pristella maxillaris in the tank – this species is restricted to the lower rio Orinoco and does not occur in the region from where the participant took his inspiration to buld his biotope.
