Live blackworms

[Woodsie]

Can these be a staple, everyday food?
Edited to add: To follow the rest of the thought through, in order to add condition to a discus are live black worms a good choice to feed three or four times a day.

generally any food high in fat and protein is low in minerals and vitamins, id still feed something with vitamins and minerals in it just to keep the fish in top shape
