Hunting and
For entertainment in the aquarium, it is important that it is kept in a shoal of at least 5 animals and a lot of hiding places in the aquarium are available. Suitable values are a water temperature of 22 ° C to 27 ° C and a pH value of 6.0 to 7.5. The water hardness should have d at a KH value of 2 ° to 5 ° and a GH of 2 ° to 15 ° d. The aquarium should be at least 60 liters.

Propagation
In the wild, the armored catfish perform after the rainy season when the water has warmed up again, their species-typical mating behavior, since a lot of suspended solids and thus prey animals are in the water after the rainy season.
Most likely to succeed in the proliferation in the aquarium after the rainy season, modeled on one to three -day cooling water by two to three degrees and rich feeding, with subsequent reheating. Best used breeding groups with a ratio of two males to one female together; the animals mate in nature in larger groups. The animals make a special mating behavior in which the male circles the female and strong twitches, the female cleans certain areas of the aquarium ( discs and leaf undersides ) to then it to staple the (100 ) eggs, which are then fertilized the male. The eggs should be separated from the mature animals. At 26 to 28 ° C, the larvae need to hatch about 5 days. The larvae are very small and almost transparent. Two to three days after hatching, when the yolk sac is depleted, the larvae can be fed with newly hatched Artemia. Later finest flake food can be given.
