Cryptocoryne nurii (Heart-leaf Water Trumpet)

03 October 2026

Cryptocoryne nurii is a small, slow-growing rosette plant from Asia, valued for its textured, often wavy leaves and tolerance of subdued aquarium lighting. The supplied label supports identification as C. nurii, although the exact cultivated form cannot be confirmed from the available material. It is best planted in the foreground or middle of a mature aquarium and should be disturbed as little as possible after planting.

Cryptocoryne nurii (Heart-leaf Water Trumpet)

Identification

The supplied product label names the plant Cryptocoryne nurii. Its compact rosette, narrow lance-shaped leaves and strongly textured or wavy surface are consistent with that identification. Cryptocoryne species can vary substantially between populations and cultivated forms, so the precise variety or locality cannot be determined here.

Placement and planting

Plant the roots in nutrient-rich sand or fine gravel while keeping the crown above the substrate. A small group can form a low, structured planting in the foreground or middle ground. Avoid burying the crown, and leave enough space for the rosette to expand.

Water and lighting

Use stable, clean aquarium water with gentle circulation and low to moderate light. It generally benefits from soft to moderately hard water and mildly acidic to neutral conditions, but gradual acclimation is more important than pursuing a narrow target range. Avoid abrupt changes in temperature or water chemistry.

Nutrition and carbon

Root-zone nutrition is useful because this plant feeds substantially through its roots. Add a controlled substrate fertilizer or root tab when growth slows, following the product instructions. Supplementary carbon dioxide is not essential, although a stable supply can improve growth and leaf development.

Growth and maintenance

Growth is usually slow. Remove damaged or melting leaves at the base and keep the filter intake from pulling on the plant. Newly planted Cryptocoryne may shed older leaves during adjustment, commonly called Cryptocoryne melt; leave the rooted plant in place and remove only decaying material.

Propagation

Propagation is normally by side shoots that develop from the rhizome or runners. Separate a young plant only after it has formed its own roots and several leaves. Replant it gently at the same depth, keeping the crown clear of the substrate.

Helanthium tenellum 'Green' (Green Dwarf Chain Sword)

Easy

Foreground

Helanthium tenellum 'Green' is a small, grass-like rosette plant used mainly in the foreground of freshwater aquariums. It spreads through slender runners and can form a low, connected carpet when planted in suitable substrate. The supplied source identifies it as the green cultivar, although cultivation conditions can make its leaf width and height variable. It is generally adaptable, but stronger light, adequate nutrients and added carbon support denser growth.
Najas guadalupensis 'Guppy Grass' (Guppy Grass)

Easy

Supporting plants

Guppy Grass is a fast-growing, delicate submerged stem plant identified here as Najas guadalupensis 'Guppy Grass'. It produces narrow, flexible green leaves along branching stems and forms dense cover for small fish and fry. It is generally undemanding, grows floating or planted, and can quickly fill open water. The exact horticultural distinction of the quoted form cannot be confirmed from the supplied material alone.
Helanthium bolivianum 'Quadricostatus' (Dwarf Chain Sword)

Easy

Foreground

Helanthium bolivianum 'Quadricostatus' is a small rosette plant used mainly in the foreground of planted aquariums. It produces narrow, bright-green leaves and can spread by runners to form a low carpet or grouped ground cover. The supplied source identifies it as this cultivar; aquarium plants sold under similar chain-sword names can be difficult to distinguish without a verified specimen, so the identification is treated as probable rather than definitive.
Cryptocoryne wendtii 'Green' (Green wendtii water trumpet)

Easy

Middleground

Cryptocoryne wendtii 'Green' is a cultivated green form of the adaptable wendtii water trumpet. It develops a compact rosette of narrow to moderately broad, gently textured leaves and is suitable for many freshwater community aquariums. It grows from a rooted crown and generally performs best when left undisturbed in a nutrient-containing substrate. The identification follows the supplied label; cultivar boundaries within commercially sold Cryptocoryne wendtii forms can be difficult to verify from photographs alone.
Utricularia graminifolia (Grassy water hose)

Advanced

Foreground

Utricularia graminifolia is a small aquatic bladderwort valued for its fine, grass-like foliage and low carpet-forming habit. It is a carnivorous plant with minute bladder traps, but these do not pose a practical risk to aquarium fish or shrimp. This species is best suited to established, stable aquariums where strong light, carbon dioxide and consistent nutrition support dense growth.
Eleocharis acicularis (Dwarf Hairgrass)

Medium

Foreground

Eleocharis acicularis is a fine-leaved sedge used as a foreground carpeting plant in freshwater aquariums. It spreads through slender runners and can form a low, grass-like cover when given suitable light, nutrients, and stable conditions. The supplied 1 2 GROW! material is labelled E. acicularis; confirmation of the exact commercial form from photographs alone is limited.
Glossostigma elatinoides (Baby Tears)

Advanced

Foreground

Glossostigma elatinoides is a small, fast-growing aquatic plant from Australia and New Zealand that is widely used to create a low foreground carpet. Its delicate, opposite leaves spread along the substrate when supplied with strong light, carbon dioxide, nutrients, and suitable planting conditions. It is best suited to established aquariums because insufficient light or unstable carbon availability can lead to sparse growth and upward-reaching stems.
Taxiphyllum sp. 'Flame' (Flame moss)

Easy

On rock or root

Flame moss is a distinctive aquatic moss sold under the trade name Taxiphyllum sp. 'Flame'. Its narrow, upright shoots twist and curl as they grow, creating a flame-like texture rather than a flat carpet. The exact species identity and geographic origin are not reliably established from the supplied material, so this article treats it as a cultivated Taxiphyllum form with conservative care guidance.
Elatine hydropiper (Water Pepper)

Advanced

Foreground

Elatine hydropiper is a very small, low-growing aquatic plant used to form a dense foreground carpet. The supplied label identifies the plant as E. hydropiper, and the appearance is consistent with that use, although a definitive identification would require botanical examination. It is best suited to established aquariums with strong light, nutrient-rich substrate, stable conditions, and reliable carbon dioxide supplementation.
