Schwartz 'armored catfish ( Corydoras schwartzi ) belongs to the family calluses and armored catfish ( Callichthyidae ), which is divided into two subfamilies , callous catfish (Callichthyinae) and armored catfish (Corydoradinae).

The Schwartz 'armored catfish from the genus Corydoras is also often referred to as the banded armored catfish .

Occurrence

Schwartz's armored catfish is native to the Rio-Purus estuary ( Brazil ) in South America. He lives there in shady river sections and jungle pools .

features

All species of the callous and armored catfish family, as intestinal breathers, are able to absorb additional oxygen from the air through gas exchange in the intestine. Used air is then released through the anus in the form of small air bubbles.

In the natural habitat of the Schwartz 'armored catfish, the whole swarm swims to the surface of the water at lightning speed and then retreats to the bottom of the water. This form of breathing enables these catfish to survive in particularly oxygen-poor waters that are cut off from the river.

Schwartz'-armored catfish females are up to six centimeters long and, compared to the males, which only reach a length of five centimeters, are significantly fuller.

Aquaristics

General

Schwartz's armored catfish can be found mostly in the lower third of the aquarium . As a schooling fish , it should be kept in a group of at least six specimens.

Facility

Overhanging roots or caves made of stone structures should be part of the facility as a retreat. To protect the sensitive barbels of the Schwartz 'armored catfish from injuries, the substrate should consist of aquarium sand or very fine rounded gravel. A floating plant cover also contributes to the well-being of the Schwartz 'armored catfish and quickly makes them lose their initial shyness.

Socialization

Schwartz's armored catfish can be socialized well with other peaceful aquarium inhabitants, who can also be much larger and have similar demands on the quality of the water. Care should only be taken that he does not miss out on feeding.

Lining

As an omnivore, Schwartz's catfish is not picky. Of live food , through frost and freeze-dried food, to the commercial flake, TABS and Chips assortments, he disdained anything. In any case, it should be fed varied, spread over the day, in several small portions.

breed

For every female there are two to three males in a species tank. Broad-leaved aquatic plants or vertical stone slabs serve as a spawning substrate. Often spawning takes place on the aquarium panes. The water should not be too hard and should be in the acidic range. The water temperature should be set to 28 ° C after a major water change with cold water.

When spawning, the females are pursued by several males. The female always holds a few eggs between the pelvic fins, where they are fertilized by the male and then attached by the female to plants, stones or the aquarium panes. After spawning, the parents, or, if possible, the spawning substrate with the eggs, should be moved to another tank with the same water parameters. The fry hatch after four to eight days, for which you should have very fine food ready when their yolk sac is used up.
