Lilaeopsis mauritiana
Lilaeopsis mauritiana
Endemic to Mauritius, this micro sword variety has distinctly narrow, cylindrical leaves. It is less light-demanding than its Brazilian cousin, making it an easier carpeting choice for mid-tech setups.

Species description
Geographical Origin and Habitat: Lilaeopsis mauritiana is native to the island of Mauritius in the Indian Ocean. It populates the sandy and muddy banks of rivers, deltas, and coastal marshy areas exposed to both freshwater and brackish conditions. The species has adapted to tolerate seasonal fluctuations in water level, growing submerged or emersed in water-saturated substrates under direct sunlight.
Taxonomy & Genetics: It belongs to the family Apiaceae, genus Lilaeopsis. This species features a hardy and stable genetic profile characterized by hollow stems and leaves that facilitate transport of oxygen to the roots in anaerobic soils. Compared to other Lilaeopsis, it shows distinct morphological features, with cylindrical leaves of circular cross-section rather than flattened ones.
Physical Structure: It develops a creeping underground rhizome from which small clumps of vertical leaves emerge at each node. The leaves are needle-like, stiff, hollow, and lack a widened leaf blade, reaching an average height of 5 to 10 centimeters. The root system consists of thin but well-anchored roots developing along the nodes of the rhizome.
Color & Texture: It displays a uniform bright green or emerald green coloration, which maintains its brilliance even under intense light. The texture is smooth, elastic, and leathery, with a tubular consistency noticeable to the touch. Under direct aquarium light, the foliage assumes a fresh and healthy look, ideal for forming small submerged lawns.
Care, breeding and tankmates
Lighting & CO2: Requires medium to high lighting to prevent the leaves from stretching and to encourage horizontal propagation of the rhizome. Carbon dioxide (CO2) injection is recommended to stimulate denser and more uniform growth, reducing carpet formation time.
Nutrition & Substrate: Prefers a sandy or fine-grained substrate to allow the rhizome to propagate without physical obstacles. While it does not have extreme demands for fertile soil, it benefits from regular column fertilization with iron, potassium, and microelements to prevent leaf yellowing.
Water Chemistry: Tolerates a wide spectrum of parameters: temperature between 20°C and 30°C, pH from 6.0 to 7.5, and carbon hardness (KH) between 2 and 14 dKH. Its exceptional tolerance to brackish water makes it suitable for setups mimicking river estuaries.
Space Management & Placement: Its ideal placement is in the foreground of the aquarium. It should be planted in small clumps spaced 2-3 centimeters apart, allowing new underground runners to gradually fill the empty spaces and form an even carpet.
Pruning: Trim the longer or damaged leaves with sharp scissors. Regular pruning stimulates the plant to produce new leaves and intensify horizontal rhizome spreading, keeping the lawn low and compact.
Risks & Diseases: Due to its slow growth, the tubular leaves can accumulate debris or be colonized by green spot algae if water circulation is poor. Nutrient deficiencies, particularly iron, manifest quickly with color loss and leaf yellowing.
