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 or tiny spatula is also acceptable.

You are purchasing a starter culture.  You will need to transport it into a bigger container upon arrival.  Ask us about our ALL IN ONE microworm cultures.




How to create a culture:

Step 1: Gather your materials

  • Mashed Potatoes
  • Dechlorinated Water
  • Small Container (take out containers with sealing lids)
  • Baker’s Yeast
  • Microworms

Step 2: Add water to the mashed potatoes until you get a mushy consistency.  It should be a the same consistency you would make if you were eating them.

Step 3: Spread the mashed potatoes to the container.  Keep it OFF the sides of the container.

Step 4: Add Microworms

Step 5: Sprinkle yeast on top

You should see worms crawling on the sides/top within 48 hours.
