Support the nutritional needs of bottom-feeding fish with Aqueon Algae Rounds. Specially formulated for bottom dwellers, these sinking rounds dissolve slowly to accommodate their natural eating habits and allow fish more time to feed. Made with premium ingredients, including natural vegetable sources such as spirulina and kelp that algae eaters prefer, the formula provides essential nutrition to support a healthy immune system, vibrant color, proper growth and vitality. Aqueon Algae Rounds are formulated so fish utilize more of what they eat, helping create less waste in the aquarium. Ideal for Hillstream Loaches, herbivorous Plecos, Dwarf Shrimp, Mbuna Cichlids, Redtail Sharks and other bottom-feeding fish. Rounds can be broken into smaller pieces when necessary to help prevent overfeeding.
