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. Click here for culture instructions.
