I had some HBH shrimp pellets that were given to me a long time ago (several years old), and my cories could not eat them. They never softened up and would still be there the next day so I threw them out (they probably had no nutritional value anyways since the were so old). Were these just to old or would a new container of these pellets break up so they could eat them? Anyways right now I feed them Wardley algae disks, flake food, frozem brine shrimp, and frozen bloodworms.
