The fish are omnivores. In an aquarium, they are fed with flake food and spirulina tablets, as well as live and frozen food. They feed only from the bottom. Feed the fish twice a day, giving them a portion that they can eat in about half an hour.



The Corydoras schultzei "black" can be bred in the home aquarium.

In the spawning tank should be placed fish in the ratio of 2 males to 1 female. Spawning is stimulated by daily changes of ½ part of the aquarium water with fresh and cooler water. Water changes are made until the females begin to spawn.

Once the eggs are fertilised by the male, they sink onto the plant leaves, decoration and the aquarium walls. In order to prevent fungal diseases, it is advisable to add some methylene blue to the water.

The eggs incubate for 3-4 days, after which the tiny larvae hatch out. During the first days of life, the fry are fed powdered dry food, and after 5-7 days begin to give artemium.
