Aquarium Plant Profiles

Barclaya longifolia, commonly known as the Orchid Lily, is an elegant bulbous aquatic plant native to Southeast Asia. It features long, undulating, ribbon-like leaves that can display striking shades of olive green to vibrant red, often with bright pink or red undersides. Known for its delicate foliage, it requires a nutrient-rich substrate and may occasionally enter a natural resting phase where it sheds its leaves. It is highly prized by aquascapers for midground to background placement but needs protection from herbivorous fish and snails due to its highly palatable, fragile leaves.

Parrot's Feather is a fast-growing, adaptable stem plant known for its bright green, delicately feathered foliage. It can grow entirely submerged but is especially famous for breaking the water surface to form thick, robust emersed shoots. Its rapid growth makes it an excellent nutrient sponge, though it requires frequent trimming to prevent it from shading out slower-growing tank mates.

A highly versatile and fast-growing stem plant that can be used as a foreground carpet, midground bush, or background plant depending on how it is trimmed. With its bright green, delicate leaves, it forms dense thickets that provide excellent hiding places for fry and shrimp.

Monosolenium tenerum, commonly known in the hobby as Pelia or Pellia, is a thalloid liverwort that lacks true leaves and stems. It forms beautiful, translucent green cushions but has a very delicate and brittle structure. Because it lacks roots and does not attach firmly to surfaces on its own, it is typically tied to rocks or driftwood, or trapped between hardscape elements where it can form a bushy mound. It is an excellent refuge for shrimp and fry, though it should be kept in low flow areas to prevent the brittle thallus from breaking apart and scattering around the aquarium.

A popular aquatic moss native to North America, prized for its unique feathery, fountain-like fronds. It naturally attaches to driftwood and rocks via rhizoids, forming dense, dark green, dome-shaped mounds that provide excellent refuge and grazing surfaces for shrimp and fry.

A highly unique and versatile stem plant from India known for its deeply lobed, fern-like leaves and strong ability to attach to hardscape. While it can be planted in the substrate where it grows upright, it is most prized for its creeping, epiphytic growth habit when attached to wood or rock. Under high light and good nutrition, the foliage develops stunning burgundy to deep red hues.

A highly popular trailing vine widely used in the aquarium hobby as a riparium or emergent plant. While its leaves will rot if kept submerged permanently, the plant thrives when its roots are suspended in the aquarium water column (often placed in hang-on-back filters or clipped to the rim). It acts as an incredibly powerful natural filter by rapidly consuming excess nitrates, while its dense aquatic root system provides excellent cover for fry and shrimp.

Schismatoglottis prietoi is a robust, relatively fast-growing aroid native to the Philippines. It strongly resembles Anubias in appearance but features softer leaves and grows noticeably faster. It is highly adaptable and can be attached to hardscape or planted directly into the substrate, provided the rhizome remains exposed to prevent rot.

Bacopa salzmannii, commonly known in the hobby as Purple Bacopa or Bacopa sp. Colorata, is a striking stem plant that develops intense purple to deep red coloration under high light and CO2 injection. While its growth pattern is similar to the classic Bacopa caroliniana, its unique coloration and slightly more demanding care requirements make it a highly sought-after midground or background accent plant.

Isoetes lacustris, commonly known as Lake Quillwort, is a unique, ancient lycophyte featuring stiff, dark green, quill-like leaves. It grows very slowly from a corm-like base and is best suited for cool-water aquariums with soft water and clear conditions. Because of its remarkably slow growth, it is susceptible to algae if lighting is excessively high without adequate balance.

A very large, robust rosette plant popular for its broad, spade-shaped leaves. It is an excellent background plant for large aquariums and is widely recognized as a favorite spawning site for Angelfish. It frequently attempts to grow emersed, eagerly sending broad leaves above the water surface to form a dense canopy.

Ammannia pedicellata, historically traded as Nesaea pedicellata, is a striking and robust stem plant known for its thick, vibrantly colored stems and contrasting foliage. It can be somewhat demanding, requiring high light and ample nutrients to prevent the lower leaves from blackening or shedding.

Red Mangroves are primarily grown in open-top aquariums, sumps, or refugiums where their intricate root systems grow submerged while the foliage remains emersed above the water line. They require high light on their leaves and strict maintenance, such as regular misting with freshwater to wash excreted salt from their foliage, but reward keepers with excellent natural filtration and a highly authentic biotope environment.

Myriophyllum tuberculatum is a stunning, finely-leaved stem plant known for its intense red to rust-colored foliage. It is one of the more demanding Myriophyllum species, requiring high light, consistent CO2 injection, and comprehensive water column fertilization (especially iron and micronutrients) to maintain its vibrant coloration and prevent lower leaves from melting or dropping. When grown in optimal conditions, its dense, feathery whorls make it a spectacular focal point in the midground or background.

A highly sought-after floating plant characterized by its vibrant red roots and round, water-repellent leaves. Under high light and slightly limited nitrates, the entire plant can flush a deep crimson red. It is excellent for absorbing excess nutrients and providing habitat for fry and shrimp, but requires low surface flow as water splashing over its leaves can cause rot.

A striking stem plant renowned for its serrated leaves that display vibrant green, purple, and red hues under intense lighting. When grown emersed, its leaves emit a distinct, strong herbal fragrance and are commonly used in Southeast Asian cuisine. In the aquarium, it forms dense, colorful thickets but requires good nutrient availability and CO2 injection to maintain optimal coloration and prevent lower-leaf loss.

An eye-catching, creeping plant native to Australia, recognized by its deeply lobed, umbrella-like palmate leaves. Under high light and CO2, it forms a dense, unique carpet or midground bush, while lower light causes it to grow taller and leggier.

Aponogeton robinsonii is a fast-growing, relatively uncommon bulb plant in the aquarium hobby originating from slow-flowing rivers in Vietnam and Laos. It is noted for its tendency to quickly produce floating leaves, making it an excellent background plant that provides natural surface cover and shaded zones for the aquarium. Unlike many other Aponogeton species, it typically thrives continuously without a dormant period under submerged conditions and frequently produces fragrant white flowers.

A striking and popular bulb plant native to the ponds and streams of Sri Lanka. It is characterized by its long, translucent, light-green to reddish-green leaves with highly ruffled or crinkled margins. Unlike some other Aponogeton species, it rarely requires a strict dormant period in the aquarium and can grow continuously for years. It is a fast grower that often produces a long flower stalk reaching above the water surface.

Staurogyne repens is a versatile, creeping stem plant highly prized for creating dense, bushy foregrounds and carpets. Originating from the Rio Cristalino in Brazil, it develops a surprisingly robust root system for a stem plant. With adequate light and regular trimming, it stays low to the substrate, making it an excellent transition plant between the foreground and midground.

Alternanthera reineckii is a prominent red stem plant that provides a striking color contrast in the aquascape. While it can survive in moderate conditions with greener foliage, it requires high light, CO2 injection, and a strong nutrient supply to exhibit its deepest magenta and red colorations and to prevent lower leaf loss.

Littorella uniflora is a unique, slow-growing foreground plant that forms small rosettes with fleshy, rigid, needle-like leaves. Native to the shores of Europe and the Americas, it spreads via runners to form a distinct, spiky carpet. It is highly adaptable, thriving in both low-tech coldwater setups and high-light CO2-injected aquariums, as well as emersed in paludariums.

Lagenandra thwaitesii is a striking, slow-growing rhizomatous plant native to the stream margins of Sri Lanka. Characterized by its long, slightly ruffled dark green leaves with distinct silver margins, it makes an excellent midground to background feature. Similar in care and morphology to Cryptocoryne and Anubias, it develops an extensive root system that benefits greatly from a nutrient-rich substrate, though its creeping thick rhizome must remain unburied to prevent rot.

Singapore Moss is a highly adaptable and robust aquatic moss. Historically confused with Java Moss (Taxiphyllum barbieri) in the aquarium trade, it grows into dense, branching mats with a slightly more fern-like structure under good lighting. It readily attaches to hardscape materials such as driftwood and rocks, making it an exceptional plant for aquascaping and providing critical refuge for shrimp, fry, and spawning fish.
