Lilaeopsis brasiliensis
Lilaeopsis minor
The classic Brazilian Micro Sword is a popular carpeting plant. With strong light and adequate CO2, it spreads via runners to form a dense, grass-like lawn ideal for the foreground.

Descrição da espécie
Geographical Origin and Habitat: Lilaeopsis brasiliensis is native to the southern regions of Brazil, Paraguay, and Argentina. It grows along the muddy margins of calm rivers, coastal lagoons, and swamps subject to flooding. The plant tolerates a moderate marine influence in coastal brackish waters, growing both submerged and emersed on waterlogged soils.
Taxonomy & Genetics: It belongs to the family Apiaceae, genus Lilaeopsis. It is the most popular and stable species of the genus in aquarism. It has a genome adapted to slow but steady horizontal growth through robust underground rhizomes with marked tolerance to environmental and brackish variations.
Physical Structure: It features a creeping rhizome that elongates in the substrate or just above it. Thin roots and clumps of vertical, stiff, and slightly spatulate or flattened leaves develop from each node. Height in the aquarium is low, reaching only 5-7 centimeters if subjected to correct lighting.
Color & Texture: The leaves show a bright green, intense, and compact color. The texture is smooth, leathery, and stiff to the touch. This solid foliage resists currents and the destructive action of burrowing fish very well, creating a compact and highly natural-looking submerged lawn.
Cuidado, criação e companheiros de tanque
Lighting & CO2: Requires very intense lighting to stimulate horizontal growth and prevent the leaves from stretching and thinning. Constant CO2 administration is highly recommended to promote the formation of a dense and compact carpet.
Nutrition & Substrate: Prefers fertile, sandy substrates or fine active soils that do not hinder the flow of rhizomes. Requires a balanced column fertilization with iron and potassium to prevent yellowing and support root development.
Water Chemistry: Tolerates a wide temperature range between 4°C and 28°C, pH from 6.0 to 7.5, and carbon hardness (KH) from 2 to 14 dKH. Its resistance makes it suitable also for cold water or low-salinity brackish aquariums.
Space Management & Placement: Ideally placed in the foreground of the aquarium (foreground). It should be planted by dividing the clump into small groups of a few stems spaced 2-3 centimeters apart; over time, the clumps will join via lateral runners.
Pruning: Pruning is performed by trimming the leaves with sharp scissors. This cut stimulates branching of the underground rhizome and encourages denser lateral propagation, keeping the lawn low and even.
Risks & Diseases: Due to its slow growth, it is highly vulnerable to colonization by filamentous algae if lighting is intense but lacking balanced nutrients or CO2. Iron deficiencies cause leaf chlorosis.

Perfil da planta
- Posicionamento
- Primeiro plano
- This plant is almost exclusively used in the foreground as a carpeting plant. It should be planted directly into the substrate in small, evenly spaced clumps. It can also be used in the midground of nano aquariums.
- Forma botânica
- Rizoma
- It features short, blade-like green leaves that resemble miniature grass. The leaves grow upward from a creeping rhizome hidden in the substrate. It maintains a low profile, especially under intense lighting.
- Crescimento
- Média
- The growth rate is relatively slow to moderate, depending on lighting and CO2. It takes time to acclimate and begin sending out runners across the substrate. Once established, it steadily forms a thick, grass-like lawn.
- Substrato
- Alta
- Commonly known as Micro Sword, Lilaeopsis brasiliensis has high substrate demands to successfully form its characteristic dense, grass-like lawn. It thrives best in a nutrient-rich, fine-grained aquasoil that provides an unhindered path for its creeping runners. The substrate should be layered around 5 to 7 centimeters deep to accommodate its extensive root system and prevent the plant from uprooting. Regular supplementation with root tabs is highly recommended if planted in inert substrates like sand or fine gravel to sustain its growth.
- Fertilização de coluna
- Recomendada
- While it absorbs some nutrients from the water, column dosing is secondary to root feeding. Liquid fertilizers help ensure micronutrients are available to the leaves. However, relying solely on water column nutrients may lead to sparse growth.
- Fertilização radicular
- Nenhuma
- A nutrient-rich substrate or root tabs are crucial for its success. Its extensive root system draws the majority of its food from the soil. Replenishing substrate nutrients periodically will sustain long-term health.
- Corte
- Ocasional
- Trimming involves mowing the carpet horizontally with curved spring scissors. Regular trimming prevents the lower layers from dying off due to lack of light. It also encourages the plant to spread laterally rather than growing too tall.
- Propagação
- Estacas
- Propagation occurs naturally through lateral runners that spread across the substrate. You can also propagate it by cutting the rhizome and replanting a healthy portion. Dividing an overgrown carpet is an effective way to multiply the plant.
- Sensibilidade
- Moderada
- It is highly susceptible to being uprooted by bottom-dwelling fish before it anchors. It can also be easily choked out by aggressive algae if flow and nutrients are imbalanced. Good water circulation around the carpet is essential.
- Função de layout
- Nano, Primeiro plano, group
- Its primary role is to create a lush, natural-looking grassy foreground. It visually grounds the aquascape and provides scale to the hardscape. It is a classic choice for Iwagumi layouts and nature aquariums.
