Especially, since I was interested in spawning some of the smaller egglayers. Many BAP reports describe the use of live baby brine shrimp for rearing larger fry, but few mention how to rear smaller species to a sufficient size to accept this food. Two excellent sources of information were found in an old T. The following article combines information from these sources with my own experience raising Paramecium cultures and I hope it will help others get started raising their own small fry.

The first kind of food young fry of small fish species need is called infusoria. Infusoria are essential for small fry such as betta fry and guppy fry, as new free-swimming fry are simply unable to feed on other live foods.
Even baby brine shrimp and micro worms may be too large for small fry. A good supply of infusoria will help your fry through the first vital days of their lives and make sure that their stomachs are always full.
An infusoria culture. How Do I Culture Infusoria? So, as a responsible breeder, you will need to culture infusoria for your fish fry. You should do this 3—4 days before you expect the fry to hatch as it takes 3—4 days for the culture to really take off. Its good if you have an established tank that likely already has significant numbers of microscopic lifeforms living in it.
Add to the tank water some organic food, such as cut grass, a rabbit pellet, or blended lettuce. Make sure that the culture has easy access to oxygen, and place the jar in a sunny spot. Over the next three to four days, you should see the water go cloudy and then clear once more.
Once you have clear water, add a little to your tank to feed your fry. Methods of Incorporating the Culture Into the Tank How you add the infusoria to the tank depends largely on your personal preference and what works for you. Some people recommend a slow siphon method that supplies a constant stream of fresh infusoria into the tank. Others recommend simply tipping half the culture into the tank. This is slightly more risky. What About Liquifry? Liquifry is a product that feeds the infusoria in the tank and promotes the growth of the small organisms that fry feed on.
Many breeders swear by liquifry, although buyers should be aware that it is not so much fish food as it is food for the fish food. The Benefits Outweigh the Risks Be aware that it is potentially possible to introduce nasties to your tank by carelessly making infusoria.
Bacteria and some non-friendly biological organisms such as dragon fly larvae can be a problem. However, I have found that, if properly managed, the risk of problems is far outweighed by baby fish which have fed well in the first few days of their lives. Stunted fry are frustrating and demoralizing to raise and may never do as well as their better-fed counterparts. It is not meant to substitute for diagnosis, prognosis, treatment, prescription, or formal and individualized advice from a veterinary medical professional.
Animals exhibiting signs and symptoms of distress should be seen by a veterinarian immediately.
How to Culture Your Own Infusoria at Home
Grass Liquifry Leave your container in the sunlight for a few days, preferably 4 to 5 days to allow your culture to grow. As the culture develops in the jar, the water will start to turn green or cloudy which indicates the growth of infusoria. Now prepare to harvest your very first infusoria. Feeding the fry To feed your fry, add a small amount of water from the jar to your fry tank. For easier feeding, harvest a small amount of infusoria from the pot using an eye dropper and squirt it directly in the reservoir where the fry is growing. As simple as that.
