Corridor black and white

Corydoras black-and-white or catfish Cory black-and-white, scientific name Corydoras leucomelas, belongs to the family (Shell or callicht catfish). The Latin word leucomelas in the name of the species consists of two separate words: “leukos” – white, “melas” – black, which indicates the corresponding color of this catfish. It is one of the most common catfish Corydoras. It is exported in large quantities and successfully bred in captivity, so it is available for sale on a permanent basis. However, there is sometimes confusion with other closely related species due to the similar spotted coloration. However, it will not be a big problem if the fish are mixed up, since they have similar habitat requirements.

It comes from South America from the territory of Peru. Inhabits the basin of the Ucayali River, the confluence of which with the Marañon River gives rise to the Amazon. It is found in small streams and rivers flowing under the dense canopy of the tropical forest. The bottom of the rivers is covered with a thick layer of fallen leaves, branches, the channel is often blocked by fallen tree trunks. The water has a rich brown color due to the high concentration of tannins formed as a result of the decomposition of plant organic matter.
