Sagittaria subulata or more commonly know as Dwarf Sag, is an ideal, undemanding foreground plant. I highly recommend this plant if you are new to Live aquatic plants or are looking for an easy plant that does well in low light.
Dwarf Sag works well as a foreground plant in large aquariums or a mid-ground plant in small aquariums.
You are buying two rooted plants.
Only plant the roots, Not the plant itself (where the green starts) in your substrate. Planting this plant too deep can cause it to melt. Adding fertilizer tabs a couple of inches from the roots is suggested.
