The biOrb Sea Lily is inspired by the delicate feather-like creatures found in the South China Sea, which live on the seabed. Use this colorful plastic sea lily to create coverage at the bottom of your aquarium. A heavy round ball at the base of the plant makes it easy to sit the plant in the biOrb and hold it in place. Suitable for all biOrb aquariums. Compatible with freshwater, saltwater, and tropical aquarium setups.
