If not, this is overkill. Grindal worms have a high proportion of fat, and promote obesity in fish if fed too much too often. feeding daily is not advisable. it must be alternated with tubifex or similar live food that has less fat and more iron. Or even with a good quality flake food (read Hikari or Tetra); If you are interested in the tubifex i have, send me a PM. they are in cocopeat and can be shipped dry.
