I mention this method here because I use it on my tanks, and the fauna related to planted aquaria do quite well with this food. I've seen small pencil fish and amano shrimp eat these worms at times. My apisto pair would only eat these when I first bought them.

I got a culture of these black worms months ago. People seem to report that they're difficult, and according to current popular sources require frequent water changes. This has not been the case for me in the slightest; if anything they reproduce too fast. I've had to toss some of the culture away at times.

The method is simple. Start with seeded filter material and old tank water in a plastic container around shoe box size. I use brown paper bags for media; perhaps a half dozen of them layered on top of each other floating. From there, it's just light aeration and top-ups to keep the water level around 1.5-3 inches, with water and media changes every month or two. All water comes from water changes. Food consists of a little flake weekly.

That's about it. Nutrient-wise this gives you something nearly indistinguishable from live, clean bloodworms.
