Good Helper - Fish will eat in their own "bowl". The suction cup is suspended, and the floating design can float with the water level, helping the fish to develop the habit of eating in a fixed position and reducing the waste of fish food. Keep Your Aquarium Clean- The fish food ring keeps the food in a specific area, it can prevent the food from floating to the unneeded places like the filter, so more food can be eaten. This is really good for reducing waste and maintaining water quality. Encourage picky eaters to eat more - If one ring is full of food, the fish will rush there, while the second ring opens, dropping specialty foods for those picky eaters. Prevent the fish from being bullied - The bully cannot occupy all the rings, so everyone has a chance to eat quietly. Fill a square fish feeder and let the more aggressive fish rush over to eat it. Once they are occupied, add floating fish food to asecondfeeding area for more timid fish. Fish Safety- no pollution to water, safe for all aquatic pets. Floating fish feeding rings can help fish develop the habit of feeding in a fixed position. color: blue Size: 7.5*5.5*3.5cm Delivery quantity: 2 pieces Warm prompt: 1.
