I definitely agree. I go to the seafood market and pick up a variety of fresh seafood, which I chop up into chunks and then freeze in ice cube trays. This way I can thaw a portion at each mealtime that has a good mix of things like squid, salmon, prawns, clams, scallops, and silversides. My eel definitely seems to love the variety. Once he learned to associate the feeding tongs with food, he'll take anything I offer.
