Most common use: Fry - young killies

Micro worm is a perfect killi fry live food. Not all killies takes micro worms just after hatch but most killies ar big enough to do it just after the infusoria stage.

All you need is a micro worm culture (which you can buy where you buy your killifish or in your local killi club or association), some kind of mixture and a container with a lid. For example you could use the 1 liter plastic box which often comes with ice cream or a 500 ml yogurt container. The thicker plastic the better as it seem like the worms are crawling easier on this. Make a small hole or 2 in the middle of the lid to allow air to the culture.

As mixture there are many possibilities. I always go for solutions which I find easy and less time robbing. My recipe is therefore as easy as instant mashed potatoes with a bit of water.
Other recipes are different kinds of cereals like oatmeal etc.
