Keep nori secure and accessible for grazing fish

Loose sheets of nori can quickly drift through the aquarium or disappear into the overflow. This adjustable nori feeder keeps the seaweed contained while allowing tangs and other grazing fish to feed from all sides.

Roll the nori, place it inside the open outer cage and secure the screw-on cap. The integrated inner cylinder gently holds the seaweed against the 10 mm honeycomb openings, making it accessible without requiring you to push it through narrow slots.

Why choose this adjustable nori feeder?

• Keeps nori contained — helps prevent loose seaweed from drifting through the aquarium or entering the overflow.
• Supports natural grazing — fish can pick at the nori through the honeycomb openings.
• Easy to fill — the open cage and removable screw-on cap make loading straightforward.
• 10 mm honeycomb openings — provide access to the nori while keeping larger pieces inside the feeder.
• Six-slot inner cylinder — holds the rolled seaweed near the outer cage while allowing water to circulate.
• Free-rotating design — moves with the aquarium’s water flow while fish graze.
• Adjustable clamp — fits rimless aquarium glass up to 19 mm thick.
• Tool-free installation — attach and adjust the feeder without additional tools.
• Reef-safe PETG — durable material suitable for use in marine aquariums.

Preparing the nori

Cut or fold the nori to a height of approximately 90 mm or less. Roll the sheet loosely, place it inside the cage and install the cap with its integrated inner cylinder.

Attach the feeder to the aquarium glass and tighten the clamp screw until it sits securely. Do not overtighten the clamp.
