Castle Dawn Aquatics Casuarina Cones are a small but powerful botanical, prized across Asia and Southeast Asia for their ability to release a rich concentration of tannins. Though similar in appearance to alder cones, Casuarina Cones provide a deeper tint and stronger blackwater effect, making them a perfect addition for Betta, shrimp, and dwarf cichlid aquariums. These woody cones not only enrich the water but also create microhabitats for shrimplets and other small aquatic life. As they gradually break down, they encourage biofilm and fungal growth, offering a natural grazing surface and an important food source for shrimp, plecos, and snails.
