Clean Easy Way to Culture and Harvest Micro worms (Nematodes) for Tropical Fish Fry, Amphibian Larvae etc.
Microworms are a harmless nematode that make a great food for tropical fish fry like guppies, bettas, and amphibian larvae (newts, salamanders and dwarf African aquatic frogs). They are very easy to culture and provide a good volume of live food once cultures are established. Materials: starter culture of microworms plastic container like a yogurt or margarine container (I prefer the 500mL size as they take up less storage space) lid with small holes in it culture medium (oatmeal, flaked potatoes etc) paper towel cut to size of the container flat wooden stick like a popsicle stick or tongue depressor (or other small piece of food-safe wood) active baker's yeast (optional) You may notice that yeast is optional! If you are starting with a liquid culture, you do not need active yeast. The yeast is just to start brand new cultures that don't have any food for the worms. Once you have a live culture, the tiny amount of media you have them in will start the bacteria, fungi and yeast
