compost worms on ebay

i bought a few ... 2oo approx brandling worms on eabay, but the instructions were rather esoteric......i believe they like fruit!
they came in a margarine tub, not full!
i ve kept them in a small plastic bin under the sink, to keep em warm and actively breeding, any idea when i ll be able to sell them on?
any1 else tried these
looking at the website there seems to be some different worm species which operate at different levels and can be used eg for fishing..... the brandling worms are too small for that i d say
