8 x Dwarf Sagittaria Subulata - Easy Live Aquarium Plants Java Moss Fern Sagittaria Subulata is an ideal foreground plant for large aquariums or in the middle of smaller aquariums. It forms a slightly dispersed group with its runners. A nutritious bottom promotes growth. If there is a shortage of micro-nutrients the plant turns pale, indicating that the aquarium may need fertiliser. This is a robust starter plant which is also suitable for the hard water that is found in many European aquariums. Free Expedited Shipping in United States
