Ecology
Occurrence
The Marbled catfish is native to the Amazon region of tropical South America. He is in Argentina, Brazil, Paraguay and Uruguay in the Rio Parana and Rio de la Plata common. The waters in which the Marbled catfish occurs, have the following water parameters:
- A GH value of 2 ° to 19 ° d
- A KH value of 2 ° to 9 °
- And a temperature of 18 ° to 28 ° C.
Reproduction
In the wild, the marbled armored catfish perform after the rainy season when the water has warmed up again, their species-typical mating behavior, after the rainy season, a lot of suspended solids and thus prey animals in the water. The animals make a special mating behavior in which the male circles the female and strong twitches. The female is looking for spawning well appropriate agencies, such as protected stones and leaves to it then staple the approximately 150 eggs, which then fertilize the males.
Nutrition

Important a soft, not sharp-edged gravel is (sand is ideal ), since the animals may otherwise violate the barbels. He can ( x 30 cm x 30 cm Standard aquarium 60 cm) stored in tanks from 54 liters.
Breeding
It is a very easy -to-grow The Art spawning is initiated (strong, sudden partial water change with temperature variations) by simulating a rainy season. For successful breeding you need a female specimen and two male. A female lays about 150 consecutively transparent - white eggs, which are glued to large leaves, stones, or simply to the aquarium glass. The females are characterized by their bulk and size against the smaller, leaner males. The eggs should be separated from the mature animals after a short time. The eggs take about 3-5 days to hatch. The larvae are very small and partially transparent. Two to three days after hatching, when the yolk sac is depleted, the larvae with Artemia nauplii can be fed. Later finest flake food from algae and compound feed can be given.
Feed
