Ideal for food (algae leaves, salad, Catappa leaves). With a rotatable clip that can be rotated in all directions. Easy to attach to the panel. Keeps the fish and invertebrates in full view while they are feeding. Prevents the food from floating into the decorations where the fish may no longer be able to reach it, thereby polluting the water. Formulated for fresh water and seawater, and for terrariums.
