The Corydoras belong to the genus actinopterygian freshwater siluriformes. Other varieties of fish have evolved a lot, but not so much Corydoras, fish are originating from the time of the Paleocene, It is very resistant and good water adapting to low oxygen. It is very well suited to community aquariums, as occupy the bottom, where they do not compete for space with other species.

Why they can be observed sometimes coming to the surface to be ventilated, but if it is recurrent is also a sign that there is too little oxygen in the aquarium. They can scroll through places where almost no water as long as the humidity of the background is high. Its size depends on the species. In aquariums it varies from 3 to the 6 centimeters but in their wild habitat can measure up 14 centimeters. Hydrodynamic or are very poor swimmers, therefore they prefer clean water with slow currents and sandy bottom, to facilitate their transfer in the search for food.
The differences between males and females are very difficult to find easy view. Almost always the female is larger than the male and his belly is swollen, It is noted more frequently as an adult or in breeding period.

Their habitat is represented by the sweet tropical not very deep water, although its adaptability is so great that range from the most tropical climates to the colder, getting itself to locate these fish species in Patagonia. Usually they travel long distances in shoals, looking for food on the bottom of lakes, rivers, estuaries and marshes. The temperature suitable for living depends on the origin of species. The ranks range from 16A ° C supporting the Corydoras South Plata in Argentina, to over 28 ° C enduring other Amazonian species.

For hatchlings a special aquarium is recommended 60 to eighty liters unfiltered background. So that the cleaner fish suits the atmosphere of the aquarium, East You must have soft sandy or gravel bottom branches, logs and consistent with natural plants illumination, nutrients and substrates environment. Must be used overdimensioned filtration to maintain controlled nitrogenous compounds, and especially ammonia makes them much harm. these fish not recommended for densely planted aquariums as, as inhabit shoal, They are very active and live on the bottom looking for food, They may end up unearthing plants. The quality of the water for an aquarium with Corydoras, It must be maintained within very specific parameters:
- pH: Between 6.2 Y 7.4

Good nutrition with living foods, water near ambient temperature 26 ° C and the neutral pH are essential for setting performed between adults shoal of one female and two or three males. The introduction of tannins is recommended either commercially or by blades, or alder wood pineapples to become more proactive at the time of reproduction. Spawning can be induced by lowering the temperature of the water about four deg, then rising gradually irla, as well as lower the water level to resemble the characteristics of the rainy season, which it is the time mate in their wild habitat. The female lays three to six eggs that are immediately fertilized by one of the male, to be then pasted into the bottom of the blades or along the aquarium.
