Flora & Fauna

Ludwigia Palustris is one of the most accessible red stem plants, displaying green upper leaf surfaces and deep reddish-pink undersides that are visible as the stems wave in current. It is far less demanding than L. arcuata or Super Red Mini, making it an excellent entry-level red plant for tanks with moderate light. Fast growth means it requires regular pruning to maintain shape.

Ludwigia Super Red (also sold as Ludwigia sp. 'Red') is the full-size counterpart to Super Red Mini, producing larger oval leaves of intense blood-red to deep crimson coloration under high light and iron dosing. Its vivid, uniform red makes it one of the most striking background plants in aquascaping. Regular trimming and replanting of cuttings maintains colour intensity throughout the stem column.

Ludwigia Super Red Mini is a highly popular aquascape stem plant producing small, rounded leaves of an intense, uniform blood-red colour that few other plants can match. The compact leaf size and bushy growth habit make it more versatile than larger ludwigia species — it works equally well in nano tanks and as a detailed midground splash of colour in larger aquascapes. Adequate iron and CO2 are key to maintaining colour intensity.

The most popular carpeting Marsilea in the hobby, producing tiny two- or four-leaf clovers on short petioles that hug the substrate to form a dense, bright green carpet. Significantly smaller than M. hirsuta, making it better suited to nano tanks and foreground work in larger scapes. Grows reliably with good light and CO₂ but is surprisingly tolerant of lower-tech conditions compared to HC Cuba. The clover-shaped leaves are charming and create an instantly recognisable, naturalistic foreground.

The smallest Marsilea species commonly available, producing miniscule two-leaf forms when submerged that create an incredibly fine, lawn-like carpet. Its wide geographic distribution makes it very adaptable to different water conditions. Under high light it carpets tightly to the substrate; in lower light, petioles elongate as the plant reaches for the surface. One of the most low-maintenance carpeting options available — more forgiving than HC Cuba or E. Belem.

Lush, feathery stem plant with fine bright-green whorled leaves. Faster-growing and more forgiving than its red cousin. Creates a spectacular soft texture in the background of planted tanks.

A beautiful, moss-like stem plant with densely packed, fine, bright green leaves that give stems a cylindrical, fluffy appearance. It grows in flowing, well-oxygenated water in the wild. Prefers soft, slightly acidic conditions and benefits from CO2. Often used in Dutch scapes as a light green accent column.

Mermaid Weed is a unique stem plant that changes leaf shape depending on whether it is emersed or submersed — submerged leaves are deeply serrated and comb-like, while emersed leaves are broader and simple. Under high light the deeply lobed leaves turn intense shades of orange and red, making it a striking colour accent in Dutch and Nature Aquarium layouts.

Fast-growing stem plant with distinctive oak-leaf-shaped leaves. Extremely easy and undemanding — grows well without CO2. The unusual leaf shape adds variety to planted tank backgrounds.

Small water lily that propagates prolifically from plantlets on its floating leaves. Produces striking red-spotted green pads. Remove surface leaves regularly to keep the plant growing compact submersed growth.

The trident java fern is a cultivar with deeply lobed, multi-pronged fronds that create an elegant, fern-like silhouette. Like all java ferns it attaches to hardscape and requires no substrate. Very low-maintenance and suitable for low-tech tanks.

Sometimes sold as 'Baby Bolbitis' or 'Mini Bolbitis', this small aquatic fern produces deeply divided fronds similar to the full-size Bolbitis heudelotii but significantly more compact and fine-textured. It attaches to driftwood and rock and grows well in moderate flow. One of the finest detail ferns in the hobby for Iwagumi and Nature Aquarium style.

A smaller, more delicate version of Christmas Moss with finer fronds arranged in the same classic triangular pattern. The smaller frond size allows for more detailed, intricate-looking moss walls and carpets compared to standard Christmas Moss. Like other Vesicularia species, it attaches readily to hardscape and can be tied, glued, or pressed onto mesh panels. Works especially well in nano tanks and detailed scapes where a finer texture is desired.

Tiny rosette plant forming grass-like tufts. One of the most challenging aquarium plants to keep long-term. Needs very soft, acidic water, strong light, and CO2.

Mini Pellia is a small liverwort that grows as a low, spreading cushion of dark green, branching thallus. It attaches readily to rock and wood and is prized for its dense, velvety texture in Nature Aquarium compositions. Slower growing and more demanding than Java Moss, it prefers cooler, well-oxygenated water with CO2.

A classic beginner stem plant with thick, succulent-looking round leaves arranged in opposite pairs along stiff stems. Growth is slow to moderate, making it easy to maintain shape. It adapts to a wide range of conditions and does not need CO2 to thrive, making it one of the most versatile aquatic plants available.

Monte carlo produces small, round leaves on creeping stems and is widely used as a foreground carpet alternative to hairgrass. It requires moderate to high light and CO2 injection to spread horizontally rather than growing upward. Its bright green colour adds a vivid pop to Nature Aquarium-style aquascapes.

Narrow, willowy leaves give this variant a graceful, feathery appearance unlike its broad-leafed relatives. Great for creating visual contrast alongside wider-leaved plants. Just as hardy as the parent species.

Eleocharis Acicularis, Needle Hairgrass, produces extremely fine, hair-like leaves that are noticeably thinner and longer than the closely related E. parvula, creating a delicate, windswept grass carpet effect. It requires good light and CO2 to spread vigorously via runners; without injection it grows slowly and sparsely. Regular trimming keeps the carpet dense and lush.

Needle Leaf Java Fern produces extremely narrow, grass-like fronds that are distinctly different from standard Java Fern. The slender leaves create a delicate, airy texture that contrasts beautifully with broad-leaved plants. It shares the same hardy, low-light, epiphytic growth habit of regular Java Fern — easy to grow attached to rock or wood.

Ludwigia Arcuata is a fine-leaved stem plant with narrow, needle-like leaves that turn deep red to orange-red under high light and iron-rich dosing, contrasting beautifully with broader-leaved green plants. It requires more light and nutrients than L. repens to achieve its signature colour. Frequent trimming promotes bushy side-shoot growth and prevents the lower stem from going bare.

A striking stem plant with relatively large, broadly oval leaves that take on vivid orange-red tones under high light. The thick stems give it its species name (crassicaulis = thick-stemmed). It requires good light, CO2, and regular fertilisation but rewards with some of the most vivid colouration of any aquatic stem plant.

Taiwan Nymphoides produces attractive round-to-heart-shaped leaves with reddish-brown mottling on the underside. It spreads by runners and can be kept compact with regular trimming. Unlike surface-growing Nymphoides, it stays submerged in good lighting. A distinctive mid-ground to background plant with a bold, pond-like aesthetic.

Unique plant with long, thin tentacle-like leaves arranged in whorls. Fast-growing, forgiving, and adaptable. Excellent hiding place for fry and shrimp.

A lesser-known species with elegant, slightly wavy narrow leaves. Grows quickly in good conditions and provides dense cover for fish and invertebrates. The emersed form produces small fragrant flowers, giving the species its name.

An exotic relative of the water lily, Barclaya Longifolia produces spectacular long, wavy-edged leaves with olive-green upper surfaces and vivid burgundy-red undersides. It grows from a bulb and prefers to be undisturbed once planted. A dramatic focal plant for larger tanks, particularly in Nature Aquarium style compositions.

Echinodorus Ozelot is a hybrid cultivar renowned for its striking green leaves adorned with irregular dark-brown to red spots, resembling the coat of an ocelot. It is a vigorous, moderately sized sword plant reaching 25–40 cm that makes an eye-catching focal specimen in the midground or background. New leaves often emerge with a reddish tint before maturing to spotted green.

Parrot's Feather is a fast-growing, feathery stem plant with blue-green whorled leaves. It grows both submerged and emersed. Excellent for ponds and unheated tanks. Grows vigorously without CO2, absorbing nutrients rapidly and helping suppress algae. In warm tanks it may require pruning weekly to keep it manageable.

Peacock Moss derives its name from the fan-like, layered fronds that resemble peacock feathers. It grows as dense, overlapping layers of triangular, feathery growth. One of the most attractive aquatic mosses for detail work on rock and wood in aquascaping. Hardy and adaptable, doing well in a wide range of conditions.

A popular stem plant producing tiny, round, bright green leaves in whorls of three to four, creating a fine-textured, dense appearance. It can be grown as a mid-ground bush or as a foreground carpet with regular trimming. Easier to maintain than HC Cuba but provides a similar compact, fine-leaved look.

A flat, ribbon-like liverwort with a deep green, glossy surface that forms dense, spreading sheets on hardscape or the substrate. It is not a true moss but is widely sold and used as one. Particularly popular in shrimp and nano tanks — the flat, broad fronds create excellent grazing and hiding surfaces for dwarf shrimp. Grows slowly and does not need attachment, but its dense structure means it can smother smaller plants if left unchecked.

A rare and highly distinctive stem plant with tiny, deeply lobed, reddish leaves that give it the appearance of a miniature oak tree underwater. Extremely sought-after in high-tech planted tanks. Requires strong light, CO2, and micronutrient-rich fertilisation to display its best colouration.

A flat, feather-like aquatic moss with a unique branching structure that differentiates it from round-leaved mosses like Java Moss. It attaches readily to rock and wood and grows as a distinctive carpet of interlocking fronds. Slower growing than Java Moss, it produces a tidier, more formal appearance and is popular in Nature Aquarium and Iwagumi layouts.

Beautiful stem plant with coppery-pink to deep red leaves under strong light. Relatively easy to grow compared to other red stem plants. An excellent alternative to Alternanthera for reliable red colour.

Pogostemon erectus is a striking stem plant with needle-like whorled leaves arranged in perfect spirals around each stem. It creates a distinctive, almost Christmas-tree silhouette. It requires CO2 and good nutrients to maintain its compact, fine-textured form.

Pogostemon Stellatus is a majestic background stem plant that produces whorls of up to eight narrow leaves per node, creating a star-burst pattern. Under intense light the leaves develop beautiful pinkish-purple tones. It grows tall and is best positioned in the background. Nutrient-hungry and demanding of CO2 but rewarding when conditions are right.
