Lid Feeding Hole Plug Set

Aquarium lid feeding holes are a practical necessity but can also become escape routes for small or jumping fish when left uncovered between feedings. This pack of 6 rubber plugs — three in 35mm diameter and three in 50mm diameter — provides a snug, push-fit seal for both standard feeding hole sizes found in glass, acrylic, and MDF canopy lids. The plugs are moulded from food-grade silicone rubber that remains pliable over years of use and will not stick or bond to the lid material over time. The slightly oversized diameter creates a friction fit that holds the plug firmly in place even with active water surface movement below. A finger tab on each plug allows easy removal for feeding without the need for tools.
