Microworms are an easy, low maintenance live food great for beginners!

They are excellent first foods for fry.  They live about 48 hours once you feed them in the tank, so this helps reduce food waste in fry tanks.

They can be kept in a small container (don’t forget they need air to breathe!).  They live in a substrate made of mashed potatoes.  Feed them fresh mashed potatoes or yeast once every other week or as needed if fry are born.  The more you feed, the more worms you will have! The more worms, the more often you have to restart the culture.

You can culture them easily by scraping them off the sides/lid of your culture.  Some people use fingers, but a Popsicle stick, Q-tip, or tiny spatula is also acceptable.
