The Dwarf Hairgrass Potted Aquarium Plant is a great plant for beginners or advanced aquarists. It is a bottom covering plant with long light green grass like leaves that will spread out in a thick carpet of grass. This makes an excellent spawning medium and foreground plant and will grow rapidly at either partially or fully submerged. Moderate lighting required. When calculating square footage, factor each pot will cover 2 square inches of space.
