Fritz Casuarina Cones 20pk Fritz Casuarina Cones are a natural botanical that releases beneficial tannins and humic acids into the aquarium, helping create blackwater conditions similar to the native habitats of many tropical fish and shrimp. They also provide natural grazing surfaces for biofilm growth and additional shelter for shrimp and fry. Suitable for freshwater aquariums, especially betta, shrimp, tetra, discus, angelfish, and other soft-water species. Quantity: 20 Cones Suitable For: Freshwater aquariums Features: Naturally releases tannins and humic acids Helps create natural blackwater conditions Provides biofilm grazing surfaces for shrimp May encourage natural breeding behaviors Ideal for shrimp, bettas, tetras, discus, angelfish, and killifish Adds a natural aesthetic to aquascapes and biotope aquariums Directions:Add 1–2 cones per gallon directly to the aquarium or pre-soak for faster sinking.
