Mounting Options
The feeder offers two primary methods for secure attachment to your aquarium:
- Method 1: Edge Clamp for Coverless Aquariums
Attach the feeder directly to the edge of your fish tank using the integrated clamp. Tighten the screw on the clamp until the feeder is securely fastened. This method is ideal for aquariums without a top cover.
- Method 2: Adhesive Sticker for Covered Aquariums
For aquariums with a cover, use the provided double-sided adhesive sticker. Clean the surface on the fish tank cover where you intend to place the feeder. Peel off one side of the sticker and apply it to the bottom of the feeder's base. Then, peel off the other side and firmly press the feeder onto the desired spot on your tank cover. Ensure a strong bond before filling the feeder.

Filling the Food Container
The feeder has a 200ml capacity and is suitable for various dry fish foods such as flakes, pellets, and strips. Open the food container lid and pour the desired amount of food. Close the lid securely to maintain freshness and prevent moisture ingress.
