Aquarium Magnetic Fish Feeding Ring Automatic Floating Water Level

• [Magnetic Aquarium Feeding Ring] Our feeding ring features a 0.79'' large-diameter, fully sealed waterproof magnet that keeps the magnet completely isolated from water, helping prevent rust, corrosion, and demagnetization over time. It securely grips glass tanks up to 12 mm thick and stays in place through strong water flow, fish collisions, and tank vibration without slipping or drifting. Unlike silicone suction cup feeders, which can lose suction as algae, limescale, and scratches build up, our magnetic design provides long-lasting, stable attachment without aging or failure
• [Aquarium-Safe & Ultra Durable] 3D-printed from cornstarch-derived PLA, this piece has a solid, smooth, and gentle construction that’s safe for bettas, guppies, community fish, and saltwater reef tanks. Its sturdy structure resists extrusion, impact, and long-term soaking, making it less likely to crack or deform and giving it a much longer service life
• [Automatic Floating & Water Level Adaptive Design] The circular feeding ring floats steadily on the water’s surface. With an over 4.72-inch connecting rod, it adapts flexibly to water level fluctuations of 0–3.54 inches, rising and falling automatically with evaporation and water changes. It keeps fish food within the feeding area, effectively preventing it from drifting, being sucked into filters, or rotting at the bottom of the tank. This helps keep the water clean and fish healthy
• [Ideal Feeding Area for Medium & Large Aquariums] The round feeding area provides ample feeding space for community fish, bettas and tropical fish. Concentrates food to avoid large fish monopolizing food, protects small timid fish for stable feeding. Not recommended for tanks ≤5 gallons; perfectly fits most common household glass fish tanks
• [Freely Adjustable Position & Low Daily Maintenance] The internal feeding ring automatically adsorbs once the external magnetic block is placed outside the tank, enabling one-second installation. You can freely slide it up, down, left, and right on the tank wall to change feeding positions conveniently during water changes and tank cleaning. The floating ring can be individually detached for quick cleaning; no frequent replacement needed, greatly reducing daily aquarium maintenance work
• [One Ring, Many Jobs] Works as a feeding zone for flakes/pellets, a containment ring for floating plants (salvinia, frogbit, duckweed) so they don't take over the tank. Smooth PLA surface rinses clean in seconds-no crevices for gunk to hide
