So I wanted to post a thread about how to properly start and maintain a microworm culture. For those of you unfamiliar with microworms as a live food they are an extremely small (hence the name lol) nematode worm approximately 2mm in length. They are a very good high protein food for fry and are also eagerly accepted by most small fish. Maintaining a culture is also very easy. You'll need: A jar or other container Dry oatmeal Water Yeast And of course a starter culture https://www.fishlore.com/fishforum/...7-microworm-starter-cultures.html#post1580358 I personally use spaghetti sauce jars such as this The microworms do need some air so poke a hole in the lid. They don't need much and extra air holes will only lead to the growing medium drying out. Now for preparing the growing medium. I use regular ol' oatmeal. Place about 1/2 cup in the jar Next add some water. 3/4 of a cup should be enough. The oatmeal should be moist with just enough water for a slight amount of standing water. Pour off any excess. The oatmeal should not be completely submerged! The microworms do not eat the oatmeal. They eat yeast. You don't need much. Less than 1/8 of a teaspoon. Just sprinkle it on top of the wet oatmeal. No need to stir. Now add your starter culture. Again you don't need much. As long as you get some wigglers in there they will multiply quickly. That goo in the middle is the starter. Place the culture somewhere dark and let them do their thing. After about 3-4 days you'll see tiny worms crawling up the sides of the container. At this point they are ready for feeding. Using a small paintbrush just swipe them off the sides of the container. You add them directly to the tank at this point but I prefer to swish the brush in a small amount of water and then feed them via eye dropper or turkey baster. They can survive up to 24 hours in the tank before drowning and wiggle incessantly, drawing the attention of your fishy friends. The culture will continue to grow and multiply for about 3 weeks. Eventually you'll notice a decrease in worms on the sides of the container. This means its time to scoop out a tiny amount of the goop in the culture and start again!
