About two thousand species of catfish inhabit the fresh water of the world. This is one of the most ancient fishes of the planet, their fossil remains discovered in sediments of the late Cretaceous period (70 million years ago).
One of the main signs is the lack of scales, often replaced by bone plates. Catfish are benthic nocturnal or crepuscular lifestyle. Among them are predators, but most species prefer detritus, vegetable foods, and benthic invertebrates. Aquarists contain up to 800 kgs, not including hybrid forms. Content are suitable for normal aquarium conditions: the stiffness of 6-12°, the temperature 22 to 26 °C. the acidity is neutral, with small deviations in one direction or another.
