Brazil, Amazonas, Manacapuru

The aquarium recreates the flooded area near the Lago Grande de Manacapuru. It is a blackwater area, due to all the surrouding vegetation. The water is very acidic and soft.

Comment by the expert

Roberto Reis: Beautiful aquarium, based on one video. Fair description of equipments and warer parameters.

Francesco Denitto: Very nice layout. Unfortunately the biological component (part of the fish species) doesn’t represent the BIN. In fact part of them such as Hyphessobrycon melanopterus, Corydoras sterbai introduced in the aquarium, live in the southernmost region of Mato Grosso (i.e. Rio Guaporé) rather than in Lake Manacapuru. Also Mikrogeophagus ramirezi (seen in the video) is not native to the Manacapuru Lake.

Donald C. Taphorn: Your tank nicely captures the “feel” of sunlight penetrating the deeply stained waters of these lakes, and you have a nice variety of species too.
