attitude
Corydorasarten Many are quite modest and are at ease with the average water levels in our tap water. The problem is the sensitive barbels of the armored catfish, which they can easily catch fire or be injured. This is for gross and especially sharp-edged gravel often. If these wounds will not infect the fish is usually lost. For this reason, the selection of the ground floor to pay attention. An injury is on sand to watch much less frequently. Basically sand at the attitude of armored catfish as a substrate is preferable. The fish stuck its head deep in the sand and filter it through their gills. You should also treat the substrate from time to time to suck the sludge and to reduce especially the seeds.
feed
look a few exceptions, mainly armored catfish from the substrate for food. Food that falls to the ground, such as food tablets is suitable particularly well as live food such as Tubifex, blood worm, but also frozen food is often taken. If you want to start is for breeding, then has a baiting with red mosquito larvae for a good spawn with me always successful.
from breeding in their native spawning Corydoras species in the rainy season. The streams in which they live will lead floods and bursting their banks. In the flooded meadows and forest soils, they found plenty of food. The
(rain) water is flowing from the mountain regions in the streams while much colder and softer! In addition, these rains are a significant drop in air pressure (low pressure) combined. All these changes are thus an external stimulus for spawning and the spawning will of the fish.
This stimulatory stimuli can also adjust the aquarium usually good and they encourage, or at least my armored catfish, each time to spawn at.
water changing with
- colder water, the temperature must still fall by 3-4 ° and was then slowly increase again.
- softer water, I usually use rain water, osmosis intended or deionized or distilled water blended exchange water are there but just as well suited
- implement or into a breeding tank, if one also takes an approaching end deep folds wait it!
- Before you should feed the fish variety, so they have a good spawn.
rearing
I collect the eggs and lead them into a small plastic dish. This is best done by rolling the eggs gently with the fingertip, they stay stuck to the fingers. The shell is filled with fresh tap water or clean fresh water aquarium, which I pick up directly behind the filter. This dish swim with the aquarium and has thus always the right temperature. The small larvae hatch there after 4-5 days, depending on the nature and function of the temperature. 2 days from their yolk sac - you eat the first one. One can implement the larvae in a small pool or even a mounting box. This must not be too large, and it is important to ensure that the little food available in the quasi. You can newly hatched Artemia nauplii rich or decapsulated Artemia. The latter has proven himself to me very much and the losses in the first days declined significantly. In the newly hatched Artemia nauplii, the egg shells are removed carefully. This may well cause digestive problems that do not cope with the small larvae. Also other small food is readily accepted. They also graze the substrate and plants for food from.  |  |
