I have read that there are thousands of species of earthworms and the ones that are best suited for composting are epigeic worms. Ideally, I would use Eisenia fetida but it's difficult to find them locally. So I have started experimenting by using worms from bait shops. I have prepared an environment for them with cardboard bedding and apple cores and potato peels. I added a handful of soil as well. Every time I open the worm bin, I will see a couple of them right at the top. Are these epigeic worms? Also I noticed that there are soil tracks on the potato peels that have just been added. It probably means that the worms have crawled on top of it. Is this a behaviorial pattern that is unique to epigeic worms? Are there other things that only epigeic worms do?
ADDITIONAL CLARIFICATION: I living in South East Asia and trying to do vermicomposting in an apartment.
