Salvinia natans is a less common floating plant with nickel-sized leaves filled with pouches of air. Large Koi love to eat salvinia and some aquatic turtles also.
Unlike other similar floating plants, Salvinia does not have long roots that drape into the water column. This small floating fern can grow into thick mats that cover the entire top of the tank and block out light from below. It's perfect for low tech aquariums and paludariums and can act as a good shading plant to prevent algae growth.
