There are several kinds of "earthworms" and the one you want,
as a killi-keeper is the "red wiggler" that is the smallest
you can get; It gets about three inches long at most. Any
good bait store should have them.
To culture them, prepare a box, a Styrofoam shipping crate
works well, by placing a mixture of 2/3 peat moss and 1/3
well composted manure. Add about three portions of red
worms for the bait store, and feed corn mean every three of
four days.
In about a month you should have a lot of worms in various
sizes. These worms are fairly tolerant to temperature -
don't let them freeze and don't let them bake. They should
be moist but not wet. Harvest them by picking them
out with your fingers.
