How do you make inforsoria?

Infusoria are microscopic aquatic organisms that can be cultured for use as live food for fish fry. To make infusoria, you can start by filling a container with water and adding a small amount of organic matter like boiled lettuce or hay to create a nutrient-rich environment. Place the container in a warm, lighted area and allow it to sit for a few days until the water becomes cloudy with microorganisms, which can then be used as food for fish fry.
