Hikari makes "First Bites" that has a picture of angle fry on it that is at most LFS's. I have also heard of squeezing egg yoke through cheese cloth (no experience here). A third option is green water, water that has been left outside with some leaves in it. The water gets all kinds of very small animals and bugs in it that fry just love. If it is too cold for bugs where you are at, this option is no good.
