in my part of the world, they have these nightcrawler machines in darn near every convience store. It's like a little fridge with cups of live nightcrawlers. They're cheap, like a $1 for 24 crawlers. I've been tempted to buy them to feed my fish, but wasn't sure for some reason. Now that it's cold, I can't get the crawlers outside anymore. What do you guys think? bait shop nightcrawlers ok?
