Aquarium Plant Comparison Guides

A striking, robust stem plant well known for its use in creating distinct 'streets' in Dutch-style aquascapes. While it grows tall and produces bright red flowers in its emersed form, the submerged form produces compact, light green foliage that grows relatively slowly compared to most other stem plants.

A classic, fast-growing stem plant known for its highly divided, feathery green leaves. While often sold to beginners, it requires relatively high light to prevent the lower portions from deteriorating and shedding needles. It forms dense, bushy thickets that provide excellent refuge for fry and shrimp.

A small, free-floating aquatic fern that forms a dense, velvety mat on the water's surface. Under high light, its green fronds can turn a beautiful reddish-brown. It is an excellent plant for providing shade and cover for fry, but its rapid growth rate requires frequent culling to prevent it from blocking all light to the plants below.

A highly popular aquarium moss characterized by its distinct, triangular fronds that closely resemble miniature pine branches. It forms dense, lush bushes when attached to hardscape and provides excellent hiding spaces for shrimp and fry.

Common Duckweed is a notoriously fast-growing floating plant that reproduces rapidly through budding and fragmentation. While it is excellent at absorbing excess nutrients and providing cover for fry, it requires frequent culling to prevent it from completely smothering the water surface and blocking light to the plants below.

Aponogeton ulvaceus, frequently traded under the contradictory name 'Compact Aponogeton', is actually a large and fast-growing bulb plant from Madagascar. It is famous for its stunning, delicately translucent light-green leaves with heavily ruffled edges. A single healthy bulb can rapidly produce up to 40 leaves, making it a spectacular centerpiece for larger aquariums. Like many Aponogeton species, it may naturally enter a dormancy period where it drops its foliage to rest before vigorously regrowing.

A robust, large-leaved rhizome plant native to Africa. It features upright, leathery, lanceolate to elliptical green leaves that make it an excellent background or midground structural plant. Like other Anubias, it is very hardy, undemanding, and should be attached to hardscape or planted with the rhizome completely exposed above the substrate.

Riccardia chamedryfolia, commonly known as Coral Pelia or Mini Pelia, is a highly sought-after aquatic liverwort that forms dense, intricately branching mats resembling miniature green coral. It is a slow-growing plant that is excellent for tying or gluing to rocks and driftwood. While it can survive in low-tech setups, it requires moderate to high light and CO2 injection to achieve its most compact, attractive growth and to prevent algae from outcompeting it.

A versatile stem plant with distinctive round, coin-like opposite leaves. While it forms a creeping carpet in its terrestrial form, it typically grows rigidly upward when submerged in an aquarium. It is particularly valued for its robust nature and ability to thrive in cooler water temperatures and unheated setups.

A classic, highly adaptable stem plant known for its oval leaves that develop attractive reddish hues under good lighting. It is one of the easiest red plants to grow in the aquarium, making it a popular choice for beginners looking to add contrast to their aquascape.

Crepidomanes auriculatum is a rare and highly sought-after epiphytic 'filmy fern' known for its exquisite, nearly translucent fronds. Because its leaves are incredibly thin, it requires pristine water conditions and stable parameters to avoid algae accumulation and thrive submerged.

One of the most popular and hardy aquarium plants, Cryptocoryne wendtii is highly adaptable and comes in numerous color variations. Known for its crinkled leaves and robust root system, it is an excellent choice for beginners. Like many Crypts, it may experience 'Crypt melt' when introduced to new water parameters, but typically bounces back from the root system.

A hardy, popular Cryptocoryne species from Sri Lanka known for its reliability and green to brownish-bronze leaves. Like many crypts, it establishes an extensive root system and propagates via subterranean runners.

A popular and highly versatile liverwort that naturally floats at the water surface, providing excellent refuge for fry and surface cover. It was famously popularized in the aquascaping hobby by Takashi Amano, who tied it to hardscape to create bright green, oxygen-pearling submerged carpets. Left to float, it is completely undemanding, but maintaining it as a submerged carpet requires intense care.

Ludwigia glandulosa is a striking, deep red to purple stem plant. Unlike many other Ludwigia species, its leaves grow alternately along the stem rather than in opposite pairs. It is a demanding plant that requires high light intensities, nutrient-rich conditions, and CO2 injection to maintain its vibrant coloration and prevent the shedding of lower leaves.

Penthorum sedoides, commonly known as Ditch Stonecrop, is a North American perennial that thrives both emersed in boggy conditions and submersed in the aquarium. Unlike many stem plants that become leggy, it is known for developing extremely dense, compact, and upright submersed stems featuring light-green, distinctively serrated leaves. It is relatively undemanding and adaptable, making it an excellent and unique bushy midground choice.

Pogostemon helferi, commonly known as Downoi or 'Little Star', is a unique stem plant that grows with a very compact, rosette-like appearance. Its crinkled, star-shaped leaves make it a highly sought-after foreground or midground accent in the aquascape. It requires stable conditions, adequate lighting, and CO2 injection to prevent melting and maintain its signature short, bushy form.

Limnophila sessiliflora is an exceptionally hardy, fast-growing stem plant often used as a beginner-friendly alternative to the more demanding Cabomba. Its bright green, finely divided leaves provide an excellent refuge for small fish and shrimp. Due to its rapid growth, it thrives in low-tech setups but will require frequent trimming to prevent it from reaching the surface and shading neighboring plants.

Bucephalandra pygmaea is a hardy, slow-growing epiphytic plant native to the fast-flowing streams of Borneo. It is highly valued in the aquarium hobby for its small size, rippled leathery leaves, and ability to thrive attached to hardscape under low light conditions. As a rheophyte, it uses strong root systems to grip tightly onto rocks and wood.

A popular and classic foreground plant that propagates rapidly via runners to form a dense, grass-like carpet. Under high lighting and good nutrition, its delicate leaves can develop an attractive reddish or brownish hue.

Cryptocoryne parva is the extremely slow-growing and smallest known species of Cryptocoryne, originating from the central highlands of Sri Lanka. Unlike many other crypts, its leaf shape and vibrant green color remain consistent under a wide variety of aquarium conditions. It is an excellent foreground and carpeting plant, though its incredibly slow growth rate requires immense patience. Once established, its deep root system makes it very hardy and resilient.

A highly popular and classic carpeting plant that forms a dense, lawn-like grass in the aquarium. While it can survive in lower-tech setups, it requires moderate to high light and CO2 injection to form a thick, vibrant carpet rapidly. It spreads horizontally via runners.

Hygrophila polysperma is an exceptionally hardy and fast-growing stem plant, making it an ideal choice for beginners. It adapts to almost any water parameter and lighting condition, though it requires frequent trimming due to its rapid, almost weedy growth.

A highly popular and versatile stem plant that adapts well to a variety of aquarium conditions. In its emersed state, it features round green leaves, but when submerged, the leaves become narrow and can develop pink to red hues depending on light intensity and nutrient limitation. Frequent trimming encourages dense, bushy growth.
