While the red wiggler is the popular worm for composting, most of us who have been doing it for a while know that the European Night Crawler is equally good at composting and has the advantage of being larger thus serving double duty as a great fishing worm. I raise both of them and their care is exactly the same.
If you are interested I can send you Kelly Slocums vermicomposting 101 as an attached file (used with permission).
All the best,
