Casuarina cones

Casuarina Cones are a natural botanical widely used in aquariums, shrimp tanks, blackwater aquascapes, terrariums, and isopod enclosures. These small cones gradually release tannins, humic acids, and beneficial organic compounds that help create a more natural environment for aquatic and terrestrial species.

In aquariums, Casuarina Cones can help slightly lower pH, soften water conditions, and provide natural antibacterial properties. They are especially popular in blackwater setups for tetras, rasboras, angelfish, bettas, shrimp, and other species that prefer tannin-rich environments. Their textured structure also offers shelter and grazing surfaces for shrimp and small fish.

For isopod and bioactive terrarium setups, Casuarina Cones serve as natural hiding spots while supporting beneficial microorganisms that become an additional food source. As the cones slowly decompose, they contribute to a healthier and more natural ecosystem.
