Description of the area surrounding the biotope: Rio Momon is close to iquitos and has beautiful views with the bonus of two indigenous villages – the Boras and the Yaguas. The climate is hot and humid, with an average relative humidity of 85%. The wet season lasts from around November to May, with the river reaching its highest point in May. The river is at its lowest in October. Rio Momon is a black-water river with slow meandering currents, dense swamps and lagoons, and abundant fish resources, including many well-known ornamental fish species.

Description of the underwater landscape of the biotope: Under the water we find sand, algae-covered stones that feed on many fish, broken tree trunks, branches and leaves that offer shelter to fry and other small fish. In high-flowing pieces the water is clean, while in the tracks with small flow is darker because fallen leaves release tannins and humic acids.

Threats to the ecology: At the moment, the different spouts formed due to the fantastic floods of the Amazon river, are disappearing, because the so called “the greatest river of the world” is in a constant withdrawal from the territory. The Amazon flow is in retreat and also the different species of fish of this rich ichthyological zone. The biotope I have made represents a tribute to the excellent aquaristic zone. I made my dream come true and to know a place that I will probably never know due to the constant damage of the area due to the Amazon river drought and human activity.
