Climatic aspects at the keeping of armoured Catfishes.
Tank catfish isn't tank catfish the must have gained acceptance within the last few years at once. There nevertheless still are gross faults in the field of keeping of these fish.
Tank catfishes come without exception from South America, they are widespread there. Man finds you locations are known to this catfish family in the northern countries, Colombia and Venezuela, to to to the southern countries. Man only thinks of Corydoras undulatus from Argentina. This one of course climatic zones are continent also differently availably, countries like Uruguay, Argentina, and show a subtropical climate to Paraguay open in contrast to it at a such great a small stretch of coast east and Südbrasiliens still stands this one an oceanic tropical climate counts. The climate Südbrasiliens is a transition climate from the tropics to the milder subtropics. This, therefore tank catfishes don't have always to be kept in this fact is extremely wrong and also can have fatal consequences for our Catfishes shall clarify the following lines.
Most tank catfishes it is content for with a temperature around the 25° C and increase also at these temperature conditions. However, it also many tank catfishes aren't these fit in the trade into this scheme. It is importantly to know basic around which tank catfishes is, is then the origin of these fish into to look up sources differently. Reports published it are very instructive books on the market but will report to Aquaristik professional journals also into much permanently where one can get rich. This is certain after this:
- Tank catfishes from Amazonien are warmth loving catfishes
e.g. Corydoras sterbai, Corydoras guapore, Corydoras caudimaculatus
- One keeps tank catfishes from Zentralbrasilien more successful at cooler temperatures
e.g. Corydoras barbatus, Corydoras macropterus, Corydoras nattereri, Corydoras prionotus
- also tank catfishes from the southern of Argentina have to be kept cooler
e.g. Corydoras paleatus, Corydoras undulatus, Corydoras carlae
This is then manners a different catfish pre-out set tongues to create differently for the cultivation also in principle. Country is is this catfish well to know again from which ones here. Even better but unfortunately aren't always ascertainable to know the exact river systems into native country biotope of our catfishes. We distinguish whether our catfishes are exposed to distinctive dry and rain periods and it is which water type here now. Three waters types are distinguished with the water-color and the dulling to SIOLI.
1. White water like the Rio Madeira, Rio Solimoes and the Amazon
2. Clear water like the Rio Tapajoz with its source rivers Rio São Manoel and Juruena and the Rio Parguaza
3. Black water like the Rio Negro or the Rio Cururu
Tank catfishes from the Amazon area, for example Corydoras stere bay are unite strong change stopped by dry and rainy season. Constantly high temperatures and large precipitations characterize these areas. A half-yearly temperature difference, of 25 ° Celsius in the spring and summer months and 27 °Celsius in the fall and winter months, comes the natural conditions of life of these beautiful tank catfishes at the sewing Estonian.
One then becomes it for example notice at the Number of eggs of the female Corydoras. One buries the catfishes almost cause the same to the whole year clutches of eggs are more smally fairly often given. On the other hand, it comes at a half-yearly change of the temperature and other impressionable environmental conditions (food, water change and flow) of then to few eggs but appropriate great number of eggs. The greatest clutch of eggs of a Corydoras stere bay was almost 300 !! with me Eggs.
One takes this one for the clear water for being Corydoras barbatus as a counterpart for it from this one sees one clearly the differences appearing at the care of tank catfishes. The also in German "Schabracken- catfish,also in German, as you call Corydoras barbatus also comes from the federal states Sáo Paulo and Rio de Janeiro in Südostbrasilien. The water temperatures in the rivers around Rio de Janeiro are the months of July till September in it approx. 21° Celsius, they increase only within the months January and February to 26° Celsius. There is a very strong fluctuation of the daily temperatures and the further one moves of the coast into the inland region particularly in the coasts and mountains section south of Sáo Paulo all the more greatly these fluctuations are.
This catfish promises these an attitude in the aquarium between 20-22 ° Celsius at flow rich water. One doesn't stick many male animals, Corydoras barbatus males hold area fights to by they each other disapprove of the flanks with the mouth and cheek game, the right pair is found soon. The clutch, in form of a grape, of eggs is then almost always put down in the aquarium near the water surface in the flow richest place. At too high temperatures this catfish very sensitive, fin clamps is and this one rocks catfishes then have to be watched. Within only few weeks these splendid catfishes can destroying, they then are the fin unites more terribly sight. Before the purchase of aquarium fish, one should !! make sure to prevent therefore whether one can offer them the corresponding or similar environment at home
Colored perches -- therefore doesn't ask any Corydoras paleatus into this with discus occupied pelvises start, as me at recently only could see an Aquaristik friend. This catfish also survives a particular time period but aquarium like an Eskimo in Congo it feels probable into this said one!
The following climate tables summarize this described together and shall clarify the differences once again in the text once again briefly. In the aquarium the temperatures could although the given temperature units aren't this one air temperatures in the tables around water temperatures of !! be like
