Fritz Aquatics Casuarina Cones Natural Décor and Health for Betta and Shrimp and Blackwater Conditions - 20 Pack

Fritz Casuarina Cones (20 pack) are all-natural botanical cones (from the Casuarina tree) that you can add to aquariums to release tannins and beneficial organic compounds. These cones create blackwater conditions, enhance shrimp and fish habitats, and add a decorative, natural touch while helping to lower pH and inhibit bacteria in the water.
