That's an awesome idea!! Gonna have to go pick up some of those! Thanks!

Brett - not bad either except I see that working better for just having the nori loose - I feel very strongly that the nori has to be rolled over the PVC pipe (think of a sushi roll but instead of rice or whatever inside, it's a PVC pipe). The tangs have to earn their nori by scraping it off the PVC. What happens this way is that no one fish can make off like a bandit with the day's allotment of nori so everyone who wants some, gets some (how very socialist of me - I blame my Swedish ancestry), there is also far less mess produced and the amount of nori actually "harvested" by the fish is much larger. And, the last little bits get picked up by the urchins and/or abalone - rolling it is really a win in my opinion..
