Red Wigglers

Red Wigglers (Eisenia Fetida) are by far the mostly widely used compost worm in the world.  They do require temperature control in the rough range of 14-25C.  They are easy to maintain and reproduce quite quickly.  Under ideal conditions, they can eat half their weight per day.  They reproduce quickly with each worm potentially laying 2-4 cocoons with each cocoon hatching multiple baby worms.
