Additionally, it aids in improving the overall health of aquarium fish by adding a natural food source for them to consume.

Types Of Infusoria

There are three main types of infusoria:

  • Green water infusoria: this type of infusoria is made up of green algae that provide a natural food source for fish fry.
  • Brown water infusoria: it is made up of bacteria, fungi, and algae and is typically found in organic-rich water.
  • Paramecium infusoria: it is a more complex type of infusoria that is made up of multi-celled organisms.

Making infusoria is an easy and cost-effective way to ensure that your fish fry have a constant supply of nutritious food. It is an inexpensive and natural way to provide your aquarium fish with the necessary nutrients for their growth and development, while also promoting overall health.
