Grindal worms (Enchytraeus buchholzi) are a small white non-parasitic worm that lives in soils around the world. They are similar to White worms that are commonly used by other aquarists as a source of food for their fish. However, these worms are smaller than White worms. Grindal worms are a great food source to feed your young fry and adult fish that stay under a couple of inches. 
 
Grindal worms make a great food source for any picky fish that require live foods.  A lot of the time, the reason why your fish aren’t breeding is due to lack of a proper food source.
 
These worms come in a piece of filter media that is used to grow the worms.  Harvesting is easy, merely remove the top layer of needle-point material and dip into your tank each day.  A complete step-by-step video is provided.
