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".

Creagrutus amoenus is most often found at a depth between 0m and 2m. However, it is not impossible to find this species at other depths.

Creagrutus amoenus prefers well oxygenated waters in current areas and rapids. It frequents fast flowing waters where the bottom is strewn with pebbles, wood or leaves carried by the current. It can be found not far from waterfalls .
