Put aquarium water into a glass or culture container.
Take cabbage or mustard that has been boiled or rotten mustard, and squeeze to take the water.
Enter the used water into the culture container containing aquarium water, and don't forget to add the cabbage or mustard that has been squeezed into the culture container.
Place the culture container in a place that is not exposed to direct sunlight and let it sit for three days.
After three days the surface of the culture container will be filled with small white animals. If it is already visible, Infusoria is ready to be made as a fodder.
To feed, use a spoon or pipette. And make sure you give enough food to taste.
