The seaweed clip is an excellent tool for feeding "Seaweed Selects" from Ocean Nutrition. To maintain the fitness of herbivorous animals, algae should be readily available. The clip is intended for underwater use and easily adheres to acrylic or glass surfaces thanks to the suction cup. The seaweed clip keeps the seaweed underwater for the fish to feed on and helps promote a very natural feeding by allowing the fish to select from the Food, little by little, over a long period of time.
