Checked out a fairly new Korean supermarket yesterday and was just perusing around when I came to the nori(seaweed sushi wrap) section. Picked up a packet of unseasoned nori to see if any of my stock will take it. I shredded them into small sections and soaked it in water for an hour. The fish approached the strange new thing floating around in their tanks and eventually took a nibble. So far so good, everybody who tried it didn't spit it out....even my blue gill. Anyone else give their fish nori?
