The "Feeding Frenzy" Seaweed Clip is an excellent tool for feeding the "Seaweed Selects" from Ocean Nutrition. The clip is for use underwater and has a suction cup for attachment to the inside surface of glass or acrylic aquariums. This clip has a stronger grip and a longer gripping surface than similar clips that have been used in the aquarium industry. The Seaweed Clip holds the seaweed underwater for the fish to feed upon and helps promote a very natural feeding by allowing fish to pick at the food, little by little, over an extended period of time.
