Colombia, Departamento de Guainía
This biotope aquarium represents the central flow of a blackwater river in the Amazon basin, particularly inspired by regions like the Atabapo River.
The setup simulates the open channel bordered by dense vegetation and tree roots on both sides. Submerged branches, palm fronds, and leaf litter cover the sandy substrate, creating natural shelters and releasing tannins that give the water its characteristic amber hue. Vertical roots and driftwood recreate the flooded forest margins, offering hiding places and visual barriers for the fish.
The lighting mimics dappled sunlight filtering through the canopy. This setup provides a realistic habitat for species like cardinal tetras and dwarf cichlids, highlighting the beauty and complexity of Amazonian aquatic ecosystems.
