Keep the aquarium clean: Fish feeding rings keep food in a certain area, it prevents food from floating in unwanted places such as the filter, allowing more to be eaten. It is easier to clean up residual feed, reduce waste and maintain water quality, thereby increasing feeding fun. Prevents fish from being bullies: Bullies can't wear all the rings, so everyone gets the chance to eat in peace. Fill a square feeder and let your more aggressive fish rush in to eat. Once they are busy, add floating fish food to a second feeding square for the more shy fish. Reasonable design: suction cup suspension, rotating device, floating design, when the water level rises or falls, rotating rod repositionable with the water level, the floating rubber is embedded in the bottom, the fish feeding ring keeps floating above the water. Safe and quality material: Molain fish feeding ring is made of high-quality PVC material, which is pollution-free and protects the health of fish. Floating feeding rings can help fish develop a habit of eating in a fixed position.
