Spirodela Polyrrhiza (Tropica Tissue Culture Cup), commonly known as Greater Duckweed, is a versatile floating plant that adds a natural, dynamic element to aquariums. Its small, round, green fronds float freely on the water's surface, creating a serene, pond-like appearance. This plant is ideal for providing shade and shelter for fish, reducing light penetration, and helping to control algae growth.
Thriving in low to moderate lighting, Spirodela polyrrhiza is easy to care for and grows rapidly, making it suitable for both beginners and experienced aquarists. Its fast growth rate aids in nutrient absorption, contributing to improved water quality. Regular thinning is recommended to prevent excessive coverage and ensure balanced light distribution to submerged plants.
