Walterworms, which are a tiny  nematode very similar to microworms, make a great fry food…the young ones are even smaller than BBS. They survive in fresh water for a long time. They’re not just a fry food, either–small adult fish such as guppies and White Clouds love them.  They are easy to culture and produce prolifically.

Walterworms are cultured in exactly the same way as microworms. Click here for culture instructions.
