Description: Blyxa aubertii is an expressedly decorative aquatic plant which is rarely commercially avaible because of its fragile leaves. Leaves are linear, 20-40 cm long, 0,5-1,5 cm wide, often reddish or olive-green. Under moderate lighting Blyxa aubertii will produce dark-green leaves, especially if nitrate is abundant. Light that is too dim or excessive shading will result in the detachment of individual leaves as they melt away from the central stem. Under bright lighting the plant will produce deep-red leaves. The red hue can be further enhanced with increase iron supplementation. The lower third of the leaf has three distinct edges, becoming more slender towards the top and finishing in a hair-thin tip. Although it develops best in soft, acid water, a satisfactory cultivation can also succeed in medium-hard, subalkaline water. Nutrient-rich substrate, strong lighting and CO2 addition is recommended to assist the plant’s growth, as strong specimens can be quite eye-catching with their 50-100 leaves. Plant-consuming fish should not be incorporated with Blyxa aubertii because they damage the sensitive leaves. The inconspicuous flowers can also be found regularly in the aquarium. They develop either above the surface or, in case of a too high water level, submersed.

Propagation of Blyxa aubertii is easily possible with rhizome division: separate side-shoot at the rhizome with about 6 leaves. Seeding cultivation is also possible, but lengthy and not easy. The white flowers on the tips of modified leaves can be pollinated manually, but that is not necessary, as the flowers are capable of pollinating themselves. With time the seeds can be seen through the walls of their encasement. When they have changed from a light green to a brownish color, it is time for sowing them in the tank. Plantlets can be moved when they have reached about 5-6 cm in height.
