The genus Enchytraeus includes about 40 species of annelid worms. The term white worm is often used for all of the species in general, but specifically it is E. albidus which is named the white worm. This species is used as fish food by aquarium enthusiasts. E. buchholzi is known as the Grindal worm. It was named for the Swedish fish breeder that first raised the worm to feed her fish.
