Fritz Aquatics Casuarina Cones are a natural, functional decor and water conditioner designed to replicate the blackwater environments of tropical streams. These small, woody cones are a favorite for shrimp and Betta keepers, providing both aesthetic beauty and essential biological benefits.

Key Benefits

• Natural Water Conditioning: These cones slowly release tannins and humic acids, which naturally lower pH levels and create the amber-tinted "blackwater" conditions that soft-water fish thrive in.

• Protective Properties: The released compounds have natural anti-bacterial and anti-fungal properties, helping to protect fish and eggs from common infections.

• Promotes Natural Behavior: The presence of these botanicals can help enhance coloration and stimulate spawning behavior in species like Bettas, Discus, and Tetras.

• Shrimp & Fry Refuge: The intricate, multi-layered structure of the cones provides a large surface area for biofilm to grow—a primary food source for ornamental shrimp—and offers vital hiding spots for tiny shrimplets and fry.

• Long-Lasting: Unlike leaves, the dense woody structure of Casuarina cones breaks down slowly, providing a sustained release of tannins for several weeks to months.

Usage & Dosing

• Application: Add 1 to 2 cones per gallon of aquarium water.

• Preparation: You can add them directly to the tank, or pre-soak them in a separate container for faster sinking.

• Maintenance: Replace or add new cones once the original ones have completely decomposed or been consumed by inhabitants.

• Ideal For: Freshwater systems, specifically Betta and Biotope setups.
