ENCOURAGES PICKY EATERS TO EAT MORE --- Some fish are more finicky than others or maybe a bit more shy and do not want to eat with the other fish. The Floating Fish Feeding Ring allows you to feed specialty foods to the pickier fish while sprinkling standard floating fish food to the general population of fish. It wont take long for your finicky fish to quickly learn that the square fish feeder is where to find their supper.RESTRAINS FISH FROM BEING BULLIES --- A great way to restrict fish in a community tank from being bullies is to use multiple floating feeding rings. Fill one square fish feeder and allow your more aggressive fish to dash over to eat. Once they are occupied, add floating fish food to a second feeding square for the more timid fish. Bullies cant hog all the rings, so add as many as you feel necessary so all your fish can eat in peace.LESSENS DEBRIS BY KEEPING FOOD CONTAINED --- By placing your pet fishs food directly into the feeder square, it restricts the flakes and pellets from floating into the filter. A clearer aquarium filter is far more effective at keeping your tanks water at a higher quality level and diminishes excess debris throughout the tank.FITS PERFECTLY IN A FISH TANK --- At a convenient size of 4 x 4 (10cm x 10cm), the lightweight Square Feeding Ring for small fish from is constructed of high-quality plastic. It comes complete with a matching black suction cup to hold it securely in place. You also have the option of allowing the fish feeder to float freely along the surface of your freshwater tank or saltwater aquarium.SAVES FISH OWNERS TIME AND MONEY --- Effective and creative, the Square Feeding Ring for your neon tetra, guppy, and goldfish is fantastic at saving money on excess food, maintaining high-quality water and reducing filter clogging. Placing your flakes into a specified area means that you can control the dispersal of food and more is eaten and less is thrown away. Less stray food and filter clogs allow you to spend less time tank maintaining and more time enjoying with your pet fish.
