Aquarium Plant Comparison Guides

Cryptocoryne sivadasanii is a rare and striking water trumpet native to the Western Ghats of India. It features exceptionally long, narrow, wavy leaves that somewhat resemble Vallisneria but grow in predictable, tufted rosettes rather than spreading aggressively via long runners. Its grassy foliage gracefully sways in the water current, making it an excellent midground or background accent that requires minimal pruning.

Bucephalandra kishii, widely known in the aquarium trade as Skeleton King or Achilles, is a highly sought-after epiphyte famous for its pronounced, rib-like leaf venation. Unlike many smaller Bucephalandra species, it develops relatively large, broad, leathery leaves. It grows notoriously slowly and thrives when attached to hardscape in areas with moderate flow. It is somewhat prone to melting during transition and greatly benefits from CO2 injection and stable parameters.

Anubias gracilis is a large, striking epiphyte characterized by its long petioles and distinct triangular, spade-shaped leaves. Due to its size, it is best suited for the midground or background of larger aquariums, or grown emersed in paludariums where it truly thrives. Like other Anubias species, it is extremely undemanding and prefers to be attached to hardscape to prevent its rhizome from rotting.

Eleocharis acicularis is a classic, highly popular grass-like plant used extensively in aquascaping to create lush, green lawns. It spreads through underground runners to form a dense carpet over time. While it can survive in lower-tech setups, it requires moderate to high lighting, a nutrient-rich substrate, and CO2 injection to carpet densely and evenly. Frequent trimming encourages horizontal runner growth rather than vertical height.

Anubias hastifolia is a striking, larger species of Anubias known for its long stems and distinctive spade- or halberd-shaped leaves. Due to its size, it is best suited for the background of larger aquariums or allowed to grow emergently in paludariums and open-top tanks. Like other Anubias species, it is extremely hardy, requires minimal care, and should have its rhizome attached to hardscape rather than buried.

Gymnocoronis spilanthoides is an extremely fast-growing, adaptable stem plant known for its distinctive spade-shaped leaves. Often considered a weed in its native and introduced habitats, it makes an excellent background plant for aquariums due to its rapid nutrient uptake, though it requires frequent trimming to prevent it from shading out other plants or breaching the surface.

Nuphar japonica is a striking aquatic plant known for its beautiful, translucent, arrow-shaped submerged leaves. Grown from a thick, fleshy rhizome or tuber, it requires a nutrient-rich substrate to thrive. If left unpruned, it may send floating lily pads to the surface, but pruning these surface leaves encourages a lush, bushy, submerged growth form. Its delicate leaves are highly palatable and prone to being eaten by herbivorous fish and large snails.

A tall, ribbon-leaved Cryptocoryne native to India. It is highly valued as a midground to background plant for its grass-like appearance and low maintenance requirements once established. Unlike some other tall Cryptocoryne species, it tends to have somewhat wider leaves and forms a robust root system.

Eleocharis vivipara, commonly known as Sprouting or Umbrella Hairgrass, is a tall grass-like plant distinguished by its unique ability to produce adventitious plantlets at the tips of its mature leaves. This creates a fascinating, dense, multi-tiered 'umbrella' effect. It is excellent for wild, natural background scapes or providing dense upper-water column cover for fry and shrimp. Due to its rapid growth and the continuous formation of new plantlets, it requires frequent maintenance and trimming to prevent it from becoming a tangled mass and shading out lower plants.

A fast-growing stem plant known for its distinct star-like leaf whorls. Under optimal conditions with strong light and CO2, it forms very dense bushes that require frequent trimming. It is particularly sensitive to macronutrient deficiencies, which often manifest as black or melting lower leaves.

Stringy Moss is an easy, adaptable aquatic moss characterized by its distinctively upright, vertical growth habit. Unlike many spreading or weeping mosses, its delicate shoots consistently grow upwards toward the light, making it a unique textural addition when attached to wood or rock in the aquascape.

While not a true aquatic plant, the sweet potato is widely used in the hobby for aquaponics and extreme nitrate reduction. The tuber or a cutting is suspended at the water's surface, allowing an extensive, dense root system to grow down into the water column while the leafy vines grow entirely emersed above the tank. The massive root network provides excellent refuge for fry and shrimp while rapidly absorbing excess nutrients.

Süßwassertang is a unique aquatic plant that is actually the gametophyte (prothallium) stage of the fern Lomariopsis lineata. Treated functionally as a moss or liverwort in the aquarium hobby, it forms dense, beautiful mounds of translucent, ribbon-like thalli. It is extremely undemanding, adaptable, and thrives in low-tech setups. Because it does not root, it is typically tied or glued to hardscape, or allowed to sink and settle in low-flow areas. It is highly valued by breeders for providing an exceptional grazing surface and dense refuge for shrimp and fry.

Taiwan Moss is a popular and versatile aquatic moss known for its dense, triangular, fern-like fronds. Similar in appearance to Christmas Moss but with a finer texture and a more weeping growth habit, it is ideal for attaching to driftwood or rocks. It provides excellent refuge for shrimp and fry and creates natural-looking aquascapes.

Hygrophila corymbosa is a robust, fast-growing stem plant known for its large, broad leaves and thick stems. It is an excellent background plant that easily reaches the water surface. It is prone to potassium deficiency, which manifests as pinholes in older leaves. While it can adapt to lower light, moderate lighting prevents it from losing its lower leaves and maintains dense growth.

An iconic bulb plant prized for its large, broad leaves that feature striking mottled patterns in red or green. It can be trained to form a compact, bushy midground by consistently trimming leaves that attempt to reach the surface, or allowed to shoot up lily pads that provide natural surface cover and shade.

Tonina fluviatilis is an exotic and demanding stem plant native to the soft blackwater rivers of Central and South America. Known for its unique, umbrella-like bright green foliage, it requires strictly soft water, an acidic pH, high lighting, and CO2 injection to thrive. Due to its sensitivity to fluctuating parameters and requirement for specialized water conditions, it is best suited for advanced aquarists.

A highly unique and demanding stem plant characterized by its tightly curled, twisting leaves. A mutant variety of Ludwigia inclinata var. verticillata 'Cuba', it requires excellent lighting, soft water, strict nutrient dosing, and injected CO2 to prevent stunting and maintain its iconic corkscrew appearance.

Nymphaea micrantha, commonly known as the Tricolor Lily, is a striking West African water lily prized for its beautifully variegated green, reddish, and brown spotted leaves. It is famously viviparous, meaning it uniquely reproduces by forming adventitious plantlets directly at the junction of the petiole and the leaf blade. Like most aquarium lilies, it is a heavy root feeder that requires a nutrient-rich substrate to thrive and maintain its vibrant coloration. To encourage compact, submerged foliage, any leaves that reach the water's surface should be pruned regularly.

Cryptocoryne undulata is a hardy and popular rosette plant recognized for its distinctive wavy leaf margins and green to brown coloration. It is highly adaptable, thriving in low-tech aquariums and developing an extensive root system, making it an excellent midground choice.

A large, robust rosette plant from South America characterized by long, ribbon-like, somewhat translucent green leaves. It develops a massive root system and is well-suited as a background plant or solitary focal point in larger aquariums. Its large, sturdy leaves serve as excellent spawning sites for species like angelfish.

A striking and unique cultivar characterized by tightly coiled, spiraling narrow leaves. Originating as a mutation in a plant nursery, it propagates rapidly via runners and adds excellent vertical texture to the midground or background of an aquascape. Emersed growth loses the characteristic twist, but submerged leaves will quickly regain their spiral shape under moderate to high light.

A highly popular and recognizable floating plant that forms rosettes of thick, velvety, ribbed leaves resembling small heads of cabbage. It develops long, trailing feathery roots that are exceptional for taking up excess nutrients from the water column and providing safe harbor for fish fry and shrimp. It requires gentle surface movement, as splashing water on its leaves can cause them to rot.

Azolla filiculoides, commonly known as Fairy Moss or Water Fern, is a highly prolific floating fern. It forms dense, velvety mats on the water surface and is famous for its ability to fix atmospheric nitrogen via a symbiotic relationship with cyanobacteria. Under high light or nutrient limitation, its leaves develop a striking reddish hue. While it provides excellent cover for fry and resting areas for surface-dwelling species, it grows aggressively and requires frequent culling to prevent it from blocking essential light to submerged plants.
