View compareAdd a splash of rustic charm and a heap of biofilm goodness with Catappa Bark, the all-natural botanical bark strip that shrimp and microfauna adore. Sourced from the Catappa tree (Terminalia arjuna), this bark serves as a shelter, grazing surface, and tannin source, all wrapped into one warm, earthy slab.
Its curved, tunnel-like shape makes it a perfect shrimp cubby, while its slow, steady breakdown releases beneficial tannins and humic substances that promote natural blackwater conditions and a thriving micro-ecosystem.
