Mondo Grass, also know as The Fountain Plant, can be a beautiful and fulfilling addition to an aquarium and has a normal variety that reaches 8 inches (20 cm) in height, as well as a dwarf variety (Ophiopogon japonicus var. kyoto) that only reaches 4 inches (10 cm) in height. It grows at a moderate rate and produces long narrow leaves, and goes best as a foreground plant, a midground plant, or along the sides of the aquarium. It is best to usually group several plants together, with small spaces between each one.
Although the Fountain Plant is a fairly hardy plant and can survive in most conditions, the water should be regularly checked to help it thrive. It needs a pH between 6.5 and 7.5, and minimal light to keep it growing and looking healthy. Make sure to perform regular water changes and fertilize regularly after each change. The bottom substrate should be nutrient-rich. Propagation of the Fountain Plant is done by planting cuttings from the side sprouts of the main plant.
