Good fit for your tank?

Good fit for

A collector sword plant
Low-tech aquariums with stable substrate and root nutrition
Shrimp and community tanks without digging fish
Keepers who prefer rooted rosette plants over frequently trimmed stems

Think carefully if

The substrate is shallow, exhausted, or regularly disturbed
The plant will be moved repeatedly
The aquarium lacks room for the mature rosette
Yeni is a trade cultivar name with limited consistent published description.

A medium rooted rosette or runner plant with broad oval to lance-shaped leaves and green, bronze, and possible red new growth. Best used for a collector sword plant; crown placement and root nutrition are important.

Growth and Appearance

Usual aquarium appearance

This medium plant has broad oval to lance-shaped leaves. Its usual colour is green, bronze, and possible red new growth. Leaf size, height, colour, and texture can change with light, substrate nutrition, CO₂, water depth, and the individual plant.

Leaves emerge from a central rooted crown, gradually forming a larger rosette.

It is normally used for a collector sword plant. During the first few weeks, watch for a firm crown, fresh roots, a new central leaf, runners, or daughter plants rather than expecting immediate outward growth.

Requirements

Substrate: Use a substrate deep enough to hold the root system. these plants benefit from root zone nutrition. keep the crown and central growing point above the substrate.
Root feeder: Yes
Water-column feeder: Yes

Essentials

Start with low to medium light.
Use a nutrient-containing substrate or add root fertiliser near the established root zone.
Plant the roots securely while keeping the crown above the substrate.
Provide gentle to moderate circulation without directing strong flow into the crown.
Keep temperature and basic water conditions stable instead of chasing one exact value.
Match the planting position to the actual mature size of the supplied plant.
A mature aquarium is helpful, but stable care matters more than a particular tank age.

Optional improvements

Stable injected CO₂ can improve growth and colour.
Water-column fertiliser can support new leaves when used consistently and carefully.
Removing heavy shade helps new central leaves develop normally.

Beginner setup checklist

Cycled, filtered freshwater aquarium
Deep enough substrate for the roots
Root fertiliser or nutrient-containing substrate
Low or moderate light
Stable water conditions
Open space around the crown
Large sword plants need open space and should not be shaded by faster stem plants.

CO₂ guidance

Injected CO₂ is recommended for the best growth, but it is not automatically required. Stable CO₂ may improve establishment, new-leaf production, colour, density, and recovery after transplanting.

Keep CO₂ stable and balance it with light, root nutrition, water-column fertilising, circulation, and oxygen. Do not raise light sharply before the plant is producing healthy new leaves.

Planting and Care

Growth rate: Slow
Growth form: Rooted, Rosette
Rooting type: Rooted
Propagation: Division, Plantlets
Emersed growth: Yes

Preparation

Remove the pot, foam, metal band, and rock wool.
Rinse the roots and inspect the crown for soft or decaying tissue.
Remove fully damaged outer leaves close to their base.
Trim only badly damaged roots. Healthy long roots can be folded gently into a deeper planting hole.
Plant one crown per position unless the purchased pot clearly contains several separate rooted plants.

Planting

Make a hole deep enough for the roots.
Place the roots into the substrate without sharply bending or crushing them.
Keep the crown and the base of the healthy leaves level with or just above the substrate.
Do not bury the central growing point.
Press the surrounding substrate gently so the plant does not float up.

Tissue-culture plants

Rinse away all culture gel.
Separate only into natural rooted crowns or small rosettes.
Plant each crown individually with the growing point exposed.

Attachment does not apply

This is a rooted rosette or runner plant. It should be planted in substrate and should not be glued or tied to wood or stone.

Do not bury the central crown.
Do not attach the roots above the substrate.
Use rocks only as temporary barriers around the planting area, not as pressure on the crown.

Leaf trimming

Use clean, sharp aquascaping scissors.
Cut a damaged outer leaf stalk close to the crown without cutting the crown itself.
Do not cut healthy leaves halfway unless shortening is unavoidable, because the cut edge will remain visible.
Do not remove a large share of healthy leaves at one time.
Remove old outer sword leaves when they yellow, shade the centre, or become badly damaged.

Selective outer-leaf removal keeps the rosette open. Heavy trimming can delay recovery for several weeks.

Propagation by adventitious plantlets and crown division

Allow plantlets to form on a flower stalk or separate side crown.
Wait until each plantlet has several leaves and visible roots.
Separate it gently with clean scissors.
Plant the new crown with its growing point above the substrate.

Do not divide a recently imported, melting, or weak plant. Allow it to establish first.

Normal adjustment

Transport, planting, and conversion from nursery conditions can temporarily slow growth or damage older leaves.

Normal signs include a firm crown, fresh white roots, a new central leaf, runners, or daughter plants.
Emersed nursery leaves may yellow or change shape while new submerged leaves develop.
Leaf colour and size may change over several weeks.

Signs needing attention

A soft crown, foul smell, spreading decay, or repeated collapse of every new central leaf.
Roots becoming black and mushy rather than firm.
Heavy algae or debris covering the newest growth.
Repeated uprooting or burial of the crown.

Suitability and Problems

Shrimp suitability: Excellent
Goldfish resistance: Low moderate
Fish damage risk: Moderate
Melt risk: Moderate
Algae susceptibility: Moderate

Common problems

Older leaves yellow or develop holes: Leaf age, root-zone nutrient shortage, physical damage, adaptation, or unstable conditions may be involved.
New leaves are pale, twisted, or very small: Root damage, nutrient imbalance, unstable CO₂, shading, or recent transplanting can cause similar signs.
Plant repeatedly floats out of the substrate: The root system may be small, the crown may be planted too shallowly, or fish may be digging around it.
Algae covers slow leaves: Excessive light, slow or stalled growth, unstable CO₂, or poor circulation may contribute.
Crown or roots become soft and foul-smelling: Deep burial, physical damage, severe melt, or spreading rot may be involved.

Do not diagnose from appearance alone

Yellowing, holes, transparent leaves, twisted new growth, red colour loss, or slow growth can have several causes. Possible causes include adaptation, root damage, unsuitable substrate nutrition, unstable CO₂, light, temperature, water changes, or physical damage.

Safe checking order

Review recent water changes, temperature shifts, and transplanting.
Compare symptoms on new central leaves with symptoms on old outer leaves.
Inspect the crown and roots for softness or decay.
Review root fertiliser age and placement.
Check water-column fertilising and CO₂ consistency where used.
Review light intensity and shading rather than assuming more light will fix pale leaves.
Change one variable at a time and judge improvement from new leaves.

Old damaged leaves will not repair themselves. Use the next several leaves to assess recovery.

Who this plant suits

Beginner tanks: Suitable for a careful beginner who can provide stable substrate and water conditions.
Shrimp tanks: generally suitable after rinsing and quarantine, with established rosettes offering shelter and grazing surfaces.
Low-tech tanks: many forms grow well without injected CO₂ when root nutrition and stability are adequate.
High-tech tanks: CO₂ can improve growth and colour, but it does not replace root feeding.
Nano aquariums: suitable only when the cultivar or species remains compact.
Community aquariums: suitable with fish that do not dig, uproot, or chew the leaves.

Important limitations

Goldfish, digging cichlids, and large plecos can uproot or damage the plant.
Large sword plants can shade much of the aquarium and consume considerable root-zone nutrients.
Old leaves recover slowly after major damage.

Plant Decision Guide

Choose it for a collector sword plant.
Choose a compact form only after checking the likely mature size of the actual nursery stock.
Choose a large sword only when the aquarium has deep substrate and open vertical space.
Choose Cryptocoryne when slow, stable rosette growth is preferred over frequent trimming.
Think carefully if the substrate is shallow, exhausted, or regularly disturbed.
Think carefully if the plant will be moved often.
Inspect the actual specimen because cultivar names, colours, and final sizes are not always used consistently.
