These aquarium fish, instead of scales, have a platelet consisting of bone tissue. This feature distinguishes them from other waterfowl. Catfish live mainly at the bottom of glass ponds and are active only at night. They feed on plant foods, but sometimes they do not disdain to feast on the leftovers from the "lord's bottom table."
Nature endowed catfish with intestinal respiration. Looking out of the aquarium, they swallow air with their mouth, which is then processed into pure oxygen. If the catfish often lingers near the surface of the water, then it is difficult for him to breathe.
The content of catfish does not require any special conditions. Water hardness should be 6-12 ° C, temperature should not exceed 22 -26 ° C. Acidity is neutral, small deviations in one direction or another will not harm the fish. Oxygen regimen is also easy to maintain.
