Wormery?

Are the special worms for wormeries the same worms I find in the manure heap or normal compost, I think they're brandlings?

I believe they are different?

They are the same type of worms, I had stopped using my wormerie for a time and when I restarted, I collected some worms from a farm midden (I didn't want to put the worms at any risk by getting them by post) and they are doing fine, composting and multiplieing, though increasing numbers depends on both feeding and temperature
