nightcrawler

I'm getting a shipment from uncle Jim worm farm this week. So I have to ask how can these worms live underwater for a couple months. I found couple dozen alive and living well from my last batch. Has anyone ever just let them live in an aquarium until the fish eat them?

So I ordered 2 lbs of European Nightcrawler Earthworms last month from Uncle Jim's to feed all my fish. I have some in a 5 gallon bucket and some in a habitat V worm bin. I been keeping them in my room and been using Uncle Jim's worm food & bedding. Things have been going great and all my fish...
