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".

Piaractus brachypomus is most often found at a depth between 0m and 15m. However, it is not impossible to find this species at other depths. This animal evolves in areas characterized by a strong presence of vegetation (aquatic and marsh plants, decaying organic matter, roots...).

This species lives near large roots, in which it can find refuge in case of danger. This type of habitat is often found not far from the banks.

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.
