Walterworms

Walterworms are a type of nematode or roundworm. Walterworms are a non-parasitic variety of roundworm and presumably feed on yeast.

What are they used for in fish keeping?
Walterworms make excellent food for fry (up to ¼”-½” and even adults of some species take them). They can be used instead of infusoria or baby brine shrimp as a first or second food.

How are “Walterworms” different from “Micro Worms”?
Micro Worms are slightly larger then the walters. Walterworms also live longer underwater and sink slower then Micro Worms. There is also a difference in nutritional content:
 * Walter Worms: 59% protein, 18% lipids, 15% fat, 3% glycogen, 2% organic acids, and 3% nucleic acids
 * Micro Worms: 48% protein, 12% lipids, 31% fat, 7% glycogen, 1% organic acids, and 1% nucleic acids
