Earthworms are different from compost worms.

how is that?

There are many different species of earth worms.
Most, if not all, of the farmed compost/bait worms are not natives. These
all tend to be top feeders and need lots of food provided for best
growth/production.

AFAIK Australian native earth worms are a mixture including both top
top/mid range feeders in places with a deep leaf litter and deep worms
in other places. The deep worms are the ones that go deep into the
earth and thus bring up minerals from the sub soil to the top, when
they come up to the top to feed.

If you want highest production in your "worm farm" then get the compost
worms nd keep the feed up. If you want to improve deep drainage, then just
spread your organic matter around in little clumps. The deep worms are
slower,but they do aerate deep down. Also tend to be the big thick worms
you see around.
