Stefan,
I suspect it's probably foetida, but I was also a bit thrown off when Wikipedia had them listed as fedida. I don't really know, for sure, though.

Ryan,
A good test to tell between red wigglers and nightcrawlers is that red wigglers aren't very mobile. If you put them in a flower pot, they'll stay there until they die. Nightcrawlers, on the other hand, are able to crawl out of the flower pot, or quickly across the flower pot. That's one reason red wigglers are great for composting... because they stay where you put them.
