Durable construction designed for longterm use and fish safety, resistant to breakage and deformation. Rotatable single suction cup allows precise placement; double suction cups provide a stable, secure hold that resists loosening. Multifunctional design fits fish tanks, aquariums, turtle tanks, and shrimp tanks; supports a range of foods to meet different dietary needs. Closed design minimizes food drift, reduces tank mess, and makes maintenance easier. Compact size and simple setup fit most standard setups; easy to install and reposition as needed. Use scenarios: In a community freshwater tank to dispense sinking pellets without scattering them across the water. In a turtle tank to deliver appropriate food near the substrate, reducing waste. In a shrimp tank to feed small granules while keeping the water clearer and easier to maintain.
