Aquatic plants to give away, swap or sell: mosses (Java, Christmas), foreground plants, stems, rhizomes (Anubias, Microsorum), bulbs and floaters. Aquarium plants grow and propagate — aquarists always have surplus to share. Pick up free cuttings near you, swap species or complete your aquascape on a budget. Caution: invasive exotic plants (water hyacinth, Nuttall's waterweed…) are banned from transfer in the EU.
