This listing is for one bunch of at least 12 stems. High- Low light, CO2 and Fertilizers are optional for faster growth. Fast growing, quickly grows into a nice bush Stem plant, so stick into your substrate and it will sprout roots. Trim and re-plant to grow more stems. Pearl grass is a great fast-growing plant which spreads out around the aquarium into dense bushes. With regular trimming it can be kept low and act as a nice carpet as well. Perfect for shrimp tanks because of its large surface area allowing for more grazing and hiding areas for the shrimp. Trimmings do not come with roots, however aquatic plants melt their roots when introduced into new substrates and it is in-fact recommended to trim roots before planting them. For this reason trimmings are no harder to plant or grow and allow us to give you a better price. If you have any questions or problems feel free to contact us!
