Hailing from South America, Lilaeopsis brasiliensis, commonly known as the Micro Sword, is a highly popular foreground plant. Its grass-like appearance and low-growing habit make it perfect for creating lush, green carpets in the aquarium. It is versatile, hardy, and suitable for both beginners and experienced aquascapers alike.

Introduction to Lilaeopsis brasiliensis

Lilaeopsis brasiliensis, frequently referred to as the Brazilian Micro Sword, is a staple in the aquascaping hobby. Originating from South America, it grows along the banks of rivers and streams, often partially or fully submerged. It is highly valued for its dense, grass-like appearance, which is ideal for creating a natural-looking carpet in the aquarium.

Growth and Care

This plant is relatively easy to care for, making it suitable for beginners. While it can survive in low light conditions without CO2 injection, providing medium to high light along with supplemental CO2 will significantly increase its growth rate and encourage a much denser, more compact carpet. It propagates through runners (stolons) that spread across the substrate.

Aquascaping Application

As a classic foreground plant, Lilaeopsis brasiliensis is perfect for the front of the aquarium. To plant, it is best to separate the pot into small portions and plant them a few centimeters apart in the substrate. Over time, the runners will connect these portions, forming a continuous, lush green lawn that provides excellent shelter for bottom-dwelling fish and shrimp.

Rotala wallichii (Wallich's Rotala)

Advanced

Background

Rotala wallichii is a delicate, fine-leaved stem plant from Asia that can develop pink to red growth tips under strong light and stable carbon dioxide. The supplied source identifies the plant as this species, although a definitive identification from a photograph alone is limited. It is best suited to experienced aquarists and is commonly used as a detailed background or midground accent.
Rotala rotundifolia 'Blood Red' (Blood Red Rotala)

Medium

Background

Rotala rotundifolia 'Blood Red' is a red stem-plant selection of the highly variable Rotala rotundifolia complex. It forms dense, upright shoots with narrow leaves and can become intensely red under strong light, adequate carbon dioxide, and balanced fertilisation. The trade name identifies the aquarium form, but appearance can vary between cultivated lines, so exact clonal identity cannot be confirmed from images alone.
Sagittaria subulata (Dwarf Sagittaria)

Easy

Foreground

Sagittaria subulata is a grass-like, stolon-forming rosette plant commonly used to create a low, natural-looking foreground or transition. Its narrow leaves vary in height according to conditions and may become taller in deeper water or weaker light. It is generally adaptable and suitable for planted community aquariums. The supplied images are consistent with this identification, although aquarium-grown forms can vary in size and appearance.
Rotala rotundifolia 'H'ra' (H'ra Rotala)

Advanced

Background

Rotala rotundifolia 'H'ra' is a colorful stem-plant cultivar grown for its narrow leaves and warm orange, pink, or reddish tones under strong aquarium lighting. It is generally sold as a cultivated form of Rotala rotundifolia, although the exact lineage and selection history are not established here. With adequate carbon dioxide, nutrients, and regular trimming, it can form a dense background group. Color intensity varies with light, nutrient availability, and general aquarium conditions.
Riccardia chamedryfolia (Coral Moss)

Advanced

On rock or root

Riccardia chamedryfolia is a compact, branching liverwort commonly sold in aquascaping as coral moss or mini pellia. It forms dense, cushion-like green growth with a finely divided, coral-like texture. This identification follows the supplied source label, although commercial liverwort names can sometimes be applied inconsistently. It is best used attached to hardscape rather than planted deeply in substrate, where good water movement and stable conditions help maintain healthy growth.
Riccia fluitans (Pond liverwort)

Medium

Supporting plants

Riccia fluitans is a small, floating thalloid liverwort that can also be cultivated underwater as a bright green cushion. It has no true leaves, stems, or roots, and spreads by branching and fragmentation. Aquarium specimens need to be secured because they naturally rise to the surface. The supplied images appear to show several different moss-like plants, so identification is based primarily on the stated source name.
Ranunculus inundatus (River Buttercup)

Medium

Foreground

Ranunculus inundatus is an Australian amphibious buttercup valued in aquariums for its distinctive, deeply divided leaves. Underwater, it forms a low to medium-height planting from creeping stems and can produce a spreading group when conditions are suitable. It is generally suitable for the foreground or lower middle ground, although strong light and regular trimming may be needed to keep growth compact. Identification is reasonably secure from the supplied source name, but cultivated forms can vary in leaf size and habit.
Pogostemon helferi (Small water star)

Medium

Foreground

Pogostemon helferi is a compact aquatic plant with bright green, strongly crinkled leaves arranged in dense rosettes. It is widely used as a foreground plant because it remains relatively short and can form groups over time. The species is associated with Southeast Asia, but exact locality information for aquarium-grown material may vary. Stable conditions, adequate light, nutrients, and carbon availability support compact growth and healthy new leaves.
Micranthemum tweediei (Monte Carlo Pearlwort)

Medium

Foreground

Micranthemum tweediei is a small, creeping South American stem plant widely used to form a foreground carpet in freshwater aquariums. Its rounded, light-green leaves are larger than those of dwarf baby tears, making it comparatively forgiving while still benefiting from strong light, reliable carbon dioxide and adequate nutrition. Plant small portions separately in moist substrate so they can root and spread without lifting.
Alternanthera reineckii 'Mini' (Mini parrot leaf)

Medium

Foreground

Alternanthera reineckii 'Mini' is a compact cultivated form of the South American stem plant Alternanthera reineckii. It develops short, densely packed shoots with red, burgundy, and pink leaves when grown submerged. The supplied identification is consistent with this cultivar, although cultivar names are commercial rather than formal botanical ranks. It is well suited to the foreground or lower middle of a planted aquarium.
