Medium Alder Cones (70 Pack)

Our Alder cones, collected from Ireland, are a staple addition to any biotope, blackwater, or shrimp-focused aquascape. They create biofilm, which serves as a natural food source for shrimp, plecos, and bottom-dwelling fish. Widely used as an alternative to Catappa Indian Almond leaves, they are believed to share similar antibacterial properties.
