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".
The rainbow snake is most often found at a depth between 0m and 1m. 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.
