Biotope presentation

The acidification of water comes from the decomposition of plants. This phenomenon changes the color of the water, which tends to turn brown. In some areas particularly rich in organic matter, the water is so dark that it is called "black water".

Colossoma macropomum is most often found at a depth between 0m and 5m. However, it is not impossible to find this species at other depths.

Not recommended

We do not recommend keeping this species in an aquarium. It has unpredictable needs which, if not met, generate significant stress, potentially leading to a shorter life expectancy, an interruption of its growth or the development of pathogens.
