The callíctidos are a family of warm water fish , which are part of the order of the siluriformes, basically this family is made up of the coridoras, commonly called catfish.
This group has characteristics that are common to all species, such as the existence on each of the two sides of the mouth, of four pairs of rigid barbels.
Barbels allow callictids to climb walls and scratch the ground in search of food.
They are fish with a somewhat primitive appearance . Catfish do not have scales, they have a series of bony plates arranged on the sides and overlapping on the dorsal part, which allow them to move on land when their habitat dries up.
These fish are able to breathe out of water , thanks to a specific respiratory system, which also helps them survive in highly polluted waters, where other fish would not be able to thrive.
