Simple and natural nutrient rich dried seaweed sheets for freshwater and marine aquarium fish. Dried Marine algae offer an irresistible, fresh flavor that naturally attracts grazing, herbivorous, and omnivorous fish like saltwater: Tangs, Angels, Damsels, Butterflyfish, Moorish Idols, and freshwater: Cichlids, Plecos, Gouramis, Goldfish, Guppies, and Livebearers. Feed in addition to a well balanced, complete feeding regiment. Break up or fold seaweed sheet(s) as needed and attach to a clip or device as desired. Remove any excess uneaten food after a few hours or by the end of day.
