Hi Sal,

I used to raise and sell African Nightcrawlers commercially.

I've since discontinued the Africans for Euro's. Both are good composters and make great castings.

For fishing, I prefer Euro's because of their thicker skin and ability to survive better in cool water.

You can get Euros to gain weight quickly by top feeding with oatmeal...they get about as fat as my little finger, and long too.

Heat affecting worms is overrated. The damp bedding cools them down well. I maintain Euros and Red Wigglers en masse in my garage, with ambient temps often well over 100 degrees in the summer. I never have a problem. If I were to put the same pans of worms outside in 80 degree weather in direct sunlight, the the bedding starts to cook...THAT is when you have a problem....Africans, Euro's, Jumpers, they will all cook in a heated up bin due to the body mass of a worm.

Thank you very much will go look at the site now
