Catappa Bark Pieces 10-Pack

Catappa Bark Pieces are sections of bark from the Indian Almond tree, offering similar benefits to Catappa leaves but with a slower, more prolonged release of tannins and humic acids. Their thicker structure takes longer to decompose, making them a longer-lasting tannin source in the aquarium. They are particularly effective at creating sustained blackwater conditions and provide grazing biofilm for shrimp over weeks to months. Ideal for betta, shrimp, and blackwater biotope setups.
