Nori is seaweed that is roasted or dried and is used in Asian cooking. In particular, the roasted type is most often used as wrappers for making rolled sushi, while the dried type is used for sushi, seaweed soup, and rice balls. Sold under many different names, the package usually says roasted or dried seaweed. When marine aquarists discovered the nutritional value of nori, being high in carbohydrates, protein, vitamins and especially minerals, they began using it to feed their saltwater herbivores. It is ideal for feeding tangs and surgeonfishes, some angelfish and blenny species, as well as many other types of algae eaters like hermit crabs and snails. What Is Nori and How Is It Used? There are usually two kinds of nori to choose from: red, which sometimes looks dark purple in color and green (but occasionally fish stores may carry a brown type that is often favored by some surgeonfish species). It usually comes packaged in full-sized sheets, but you may find it already cut up into pieces and prepackaged by some aquarium stores or suppliers.
