Bullies can't carry all the rings, so add as many as you need so all your fish can eat in peace.Keep the Tank Clean: Fish feeding rings keep food in a certain area, they prevent food from floating in unwanted places such as the filter, allowing more food to be eaten. It is easier to clean up residual feed, reduce waste and maintain water quality, increasing feeding fun.High-quality materials: The floating feeding ring is made of high-quality rubber and plastic, environmentally friendly and safe for your fish, considered an ideal fish feeder.Perfect for aquariums: Suction cup suspension, rotating device, floating design, when the water level rises or falls, rotating rod can be repositioned with the water level, the floating rubber is built into the bottom, the fish feeding ring continues to float above the water.Feeding ring size: The size of the square feeding ring is 10 x 10 cm and the round one is 7.5 x 7.5 cm, suitable for various aquariums and fish tanks.
