Keeps Fish Tanks Clearer for Longer --- Instead of sprinkling the fish food all across the top of your aquarium, the floating feeder gives food a specific area of its own. By placing food directly into the Feeding Rings, there is less loose food roaming around the tank. Fewer pieces of wayward food mean a clearer tank and less maintenance. Reduces Food Leftover and Avoids Bullying --- Using the Fish Feeding Rings is an easy and efficient way to minimize dropping of leftover food and discourage bullying amongst your fish. Keeping the food in a certain area restricts extra flakes and pellets from scattering and getting pulled into the water filter. Giving your fish separate feeding spots, bully fish can't hog all the rings and your timid fish can eat in peace. Perfect for All Floating Fish Food --- The pair of Feeding Rings are specially designed for floating food only, as sinking food will not stay within the frames for very long. All sorts of floating foods can be put into the floating feeders where they will remain until your fish are ready to eat. Flakes, granulars, pellets and leaves are just a few of the many suitable fish foods. Durable Product Goes Inside the Tank --- All of the materials used in crafting the set of 2 Fish Food Feeders are innocuous to your aquatic pets. The black plastic frames and included suction cups are long-lasting, durable, and odorless. These materials are suitable for both freshwater and saltwater habitats. The Square plate is the bigger one with 4-inch (10 cm) length and the round plate has a 2-inch diameter (5.5 cm), so you can use them according to your need. Great for Many Species of Aquatic Pets --- Goldfish, guppies, catfish, tetras, mollies, and danios are just a few of the many fish that will eat from the convenient fish food feeders. In particular, territorial fish such as bettas and cichlids benefit from having their own area to feed from. Other aquatic pets like water turtles, shrimp, crayfish, and African dwarf frogs can also use the floating feeder rings.
