Ben,
  After breaking my cichlid tank and selling them, I had a pack of blood worms left over.  They were sitting in my freezer for about 4 months, when I saw it I decided to feed my damsels, clowns, six line etc....  They ate it and their still here with me till this day.  Again, this was leftover bloodworms. If I had a choice I'd go with mysis shrimp. Hope that helped... :mrgreen:
