Brilliant scarlet-red, blade-shaped macroalgae — one of the most visually striking species for display refugia. Provides excellent colour contrast and nutrient export. More delicate than Chaeto; requires moderate flow and consistent light. Popular with collectors and stunning under reef lighting.
Dream Blue Shrimp
Neocaridina davidi
Duckweed
Lemna minor
Duckweed is the smallest flowering plant and one of the fastest-growing aquatic plants available. It provides effective nutrient export and surface shade while serving as live food for herbivorous fish. It can quickly cover the entire surface if not managed.

Dwarf Anchor Catfish
Hara jerdoni
Dwarf Baby Tears
Hemianthus callitrichoides
The smallest aquarium plant in the world, native to Cuba. Forms a dense bright green carpet highly prized in Nature Aquariums and iwagumi layouts. Requires high light, CO₂ injection, and a nutrient-rich substrate to thrive.
Dwarf Blue Crayfish
Cambarellus diminutus
Dwarf Blue Diamond Shrimp
Neocaridina davidi
Dwarf Chain Loach
Ambastaia sidthimunki
Dwarf Chain Sword
Helanthium tenellum
Dwarf Chain Sword is a popular foreground stem plant with delicate, narrow green leaves that form dense carpets in aquariums. It grows relatively quickly and produces runners that spread horizontally, making it ideal for creating lush carpet effects. This plant is undemanding and tolerates a wide range of water conditions, making it excellent for beginners.
Dwarf Emerald Rasbora
Celestichthys erythromicron
Dwarf Gourami
Trichogaster lalius
Dwarf Hairgrass
Eleocharis parvula
Dwarf hairgrass forms a lush, grass-like carpet in the foreground of aquascapes. It requires moderate to high light and injected CO2 to spread effectively, otherwise growth is sparse and slow. Regular trimming encourages lateral runners and a denser mat.
Dwarf Hairgrass Mini
Eleocharis pusilla
Eleocharis pusilla (Dwarf Hairgrass Mini) is a nano-scale hairgrass species producing extremely fine, short blades reaching only 3–5 cm, making it noticeably shorter and denser than standard Dwarf Hairgrass (E. parvula). Under CO2 injection and good light it spreads rapidly via runners to form a tight, lawn-like foreground carpet highly prized in Nature Aquarium-style layouts. It is particularly effective in nano aquariums where even E. parvula would be too tall.
Dwarf Mexican Brown Crayfish
Cambarellus montezumae
Dwarf Mexican Crayfish
Cambarellus patzcuarensis
Dwarf Neon Rainbowfish
Melanotaenia praecox
Dwarf Orange Crayfish
Cambarellus sp. orange
Dwarf Pencilfish
Nannostomus marginatus
Dwarf Puffer
Carinotetraodon travancoricus
Dwarf Red Lily
Nymphaea rubra
Deep red lily with arrow-shaped submerged leaves. Will send lily pads to the surface if not trimmed. Beautiful red accent plant from a bulb.
Dwarf Water Lettuce
Pistia stratiotes 'Dwarf'
Miniature form of Water Lettuce with rosettes under 2 inches. Long trailing roots. Better for smaller tanks than the full-sized version.
Eastern Rainbowfish
Melanotaenia splendida
Echinodorus Aflame
Echinodorus sp. 'Aflame'

Echinodorus Bleheri, the Broad-Leaf Amazon Sword, is the quintessential large background plant of the freshwater aquarium. It produces broad, bright-green lanceolate leaves that can reach 50 cm, creating a dramatic focal point in larger tanks. It is a heavy root feeder and benefits greatly from nutrient-rich substrate or regular root tab fertilisation.
Echinodorus Kleiner Bar
Echinodorus Kleiner Bar
Echinodorus Kleiner Bar is a compact sword plant with distinctive narrow, lance-shaped leaves that display prominent red or reddish-brown barring patterns. This mid-sized stem plant grows moderately and is ideal for midground placement, offering attractive foliage without overwhelming smaller aquascapes. It is relatively undemanding and suitable for intermediate aquarists seeking a colorful accent plant.
Echinodorus Oriental
Echinodorus Oriental
Echinodorus Oriental is a medium-sized sword plant featuring distinctive reddish-brown to olive-green leaves with prominent veining and a slightly wavy margin. It grows as a rosette from a rhizomatous base and is moderately fast-growing, making it suitable for midground to background placement in larger aquariums.
Echinodorus Ozelot
Echinodorus 'Ozelot'
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.
Echinodorus Radicans

Very large sword plant with broad heart-shaped leaves. Grows emersed readily. Needs large tanks (55+ gallons). Virtually indestructible.
Echinodorus Red Rubin
Echinodorus Red Rubin
Echinodorus Red Rubin is a stunning sword plant prized for its deep red to burgundy leaf coloration, which intensifies under high light and nutrient-rich conditions. This mid-sized stem plant features broad, lance-shaped leaves and moderate growth rate, making it an excellent choice for midground to background placement in planted aquariums.
Echinodorus Reni
Echinodorus sp. 'Reni'
Compact red-brown sword plant. Stays small enough for midground use. One of the smallest red Echinodorus varieties available.
Echinodorus Uruguayensis
Echinodorus uruguayensis
Echinodorus Uruguayensis is a large, bold sword plant from South America producing broad, dark-green leaves with a smooth texture and prominent venation, reaching up to 60 cm in height. It is notable for tolerating cooler water than most tropical swords, thriving at temperatures as low as 16 °C. Its imposing size makes it best suited as a specimen background plant in larger aquariums.
Echinodorus Vesuvius
Echinodorus Vesuvius
Echinodorus Vesuvius is a striking sword plant with deeply lobed, reddish-brown leaves that resemble a volcanic eruption, hence its name. This mid-sized stem plant grows upright and develops intricate leaf patterns with prominent veining. It is moderately demanding but rewarding for aquarists seeking dramatic foliage color and texture.
