Blackworms (Lumbriculus variegates) are an excellent live food for fish and aquatic amphibians. I have been culturing blackworms for a short time, but they are thriving. This is not a blackworms culture guide…but I would like to share my current blackworm culture methods and how they have helped me produce thousands of blackworms.
