(1) Full 8 oz sealed package of cultured Vinegar Eels.  

This is a large producing culture with 1000's of worms! 


There is no quicker way to start a big culture.

Vinegar Eels are a common first food for betta fry, corydoras fry, killifish fry, and many other fish species that have very small fry hatch from eggs. They’re smaller than most nematodes, last longer in the tank, and swim throughout the water column which prevents too much bottom-feeding.  Micro worms on the other hand will settle on the bottom of the tank. That's the difference between vinegar eels and micro worms.

Vinegar eels are very easy to keep and even with minimal attention a culture can thrive for years. It is a must-have food for all tiny fish breeders.  

While other cultures might crash or brine shrimp hatches might fail, you will always be able to pull out vinegar eels and know they are ready to harvest when you need them.


Culturing Directions:

What you need:

  • Jar or large bottle (2-4L) with a cap or lid.
  • 1 small apple, cut into slices small enough to fit into the jar
  • Apple cider vinegar
  • Treated tap water
  • Starter culture of vinegar eels taken from an established culture


  • Fill the jar with a 1:1 ratio of apple cider vinegar and treated tap water, leave a little space at the top for air and also make sure to cut a small air hole in the top of the jar.
  • Wash the apple thoroughly to remove any contaminants on the skin. Cut it into pieces and stick into the jar with the diluted vinegar.
  • Add the starter culture to the jar
  • Seal and store at room temperature. A dark cabinet is preferable but not necessary

(Note: Some people add a small pinch of sugar or yeast to their cultures to start them. I’ve never tried this myself and find it an unnecessary step. The apple will act as food for the culture).

I split my cultures and start fresh cultures every 6 months or so, sometimes letting it go as long as a year. In that time, I do not add any food or fresh water/vinegar to the culture.  The colony thrives on its own very well. If you notice it getting very cloudy it’s probably time to refresh the culture. 

To refresh simply get a new jar and pour half the culture in there then top both jars off with fresh diluted vinegar. 

Depending on the size of your starter culture you should find your culture ready to feed in about 2-4 weeks, sooner if you buy a large starter. 

If you have good eyesight or a magnifying glass you will be able to see the eels swimming around in the jar, if you cannot see them a ready to feed culture will look just the slightest bit cloudy when teeming with eels.
