Between Canadian nightcrawlers and regular night crawlers? At wally-world, they sell 2 kinds, the Canadians and the regular. And as usual, when I ask the clerk what the difference is, he just shrugs his shoulders at me. I have noticed that the Candians are much larger, but are they really from Canada? Or is it just a name attached to a larger worm? And does anyone here have their own worm farm? Really the only time I use night crawlers is to either catch bait fish or when I take little ones fishin. That way Im fairly certain they will catch some fish.
