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 SunGrow 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 won’t 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 can’t 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 fish’s 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 tank’s water at a higher quality level and diminishes excess debris throughout the tank.
