Cryptocoryne wendtii is one of those plants that quietly holds a scape together.
It doesn’t scream for attention the way bright red stems do. Instead, it sits in the middle of the tank, soft waves in its leaves, giving a sense of depth and “jungle” without needing extreme care.
There are many forms – Green, Brown, Tropica, and others – but their basic care is almost the same. In this post, I’ll treat them as one cozy family.
If you’re still choosing plants and want to see where crypt wendtii sits among my other favourites, you can look at this overview page: Aquarium Plants: Simple Guide to What I Actually Use.
Quick Profile
-
Name: Cryptocoryne wendtii
-
Common forms: Green, Brown, Tropica (and other locality variants)
-
Placement: Midground, lower background, around hardscape
-
Size: Around 10–25 cm depending on variety and conditions
-
Growth rate: Slow–moderate
-
Difficulty: Easy–medium
-
Type: Rosette plant (strong root feeder)
Crypt wendtii is often recommended for beginners, but it still teaches one important skill: patience. It doesn’t always look amazing on day one, but over months it becomes one of the most stable, grounding plants in the tank.
What Makes Crypt Wendtii So Useful?
A few reasons people keep coming back to it:
-
Flexible look: Green, brown, reddish, or slightly hammered leaves depending on variant and light.
-
Great “anchor” plant: Fills the midground, softens hardscape, makes the layout feel mature.
-
Forgiving: Tolerates a wide range of water parameters once settled.
-
Slow but steady: Doesn’t explode and take over, but also doesn’t just vanish unless badly stressed.
It fits both low-tech tanks and more advanced planted scapes, which makes it a very “long-term” plant.
Tank Size and Water Parameters
Cryptocoryne wendtii fits into:
-
Small tanks (as a central midground plant)
-
Medium and large tanks (as a group or “bush” in the center)
Approximate water parameters:
-
Temperature: 22–28°C
-
pH: 6.0–7.5
-
GH: Soft to medium-hard
-
KH: Low–medium
Most treated tap water in Indonesia/Malaysia is usually fine. Crypts care more about stability than perfect numbers. Sudden big changes in water chemistry can trigger melt.
Light: It Doesn’t Need Extreme Brightness
Crypt wendtii is comfortable in low to medium light.
-
Low light
-
Leaves may grow a bit taller and narrower.
-
Growth is slower, but plant is still healthy.
-
Good option if you want a calm, low-maintenance tank.
-
-
Medium light
-
Bush becomes denser and fuller.
-
Colors can be slightly richer (especially Brown or Tropica).
-
Growth is still moderate, not super fast.
-
Very high light is not necessary and, without strong CO₂ and careful nutrients, may just bring more algae.
For a home tank:
-
Start with 6–8 hours of light per day.
-
Adjust slowly if algae appears or plants look stressed.
CO₂: Helpful, But Not Required
You can keep wendtii with or without CO₂.
With CO₂
-
Slightly faster growth
-
Denser, fuller clumps
-
Better color expression on some variants
Without CO₂
-
Absolutely fine in many tanks
-
Growth is slower but still stable
-
Focus more on substrate quality and steady conditions
If you’re not injecting CO₂, just avoid combining very strong light + minimal nutrients, because that combination tends to produce algae more than plant health.
Substrate and Nutrients
Cryptocorynes are classic root feeders. This is where they really show their preferences.
Best: Nutrient-Rich Substrate
-
Aquasoil or enriched planted substrate works very well.
-
Plant wendtii directly into it.
-
Roots will dig deep and form a strong base.
-
Often, no need for root tabs in the beginning.
Alternative: Sand or Inert Gravel + Root Tabs
If you prefer a sand or neutral gravel look:
-
Place root tabs under and around each crypt clump.
-
Renew root tabs periodically as they deplete.
-
Keep a decent depth of substrate so roots can spread.
Liquid fertilizer is still helpful, especially for the rest of the tank, but crypts respond strongly to food in the root zone.
How I Plant Cryptocoryne Wendtii
You’ll usually receive it in a pot or as loose crowns.
Step 1 – Prepare the Plant
-
Remove from the pot and pull away all rock wool or sponge.
-
Rinse gently in clean water.
-
Separate into individual crowns – each with its own root bundle and leaf base.
Step 2 – Planting
-
Make a small hole in the substrate with your finger or tweezers.
-
Place the roots in the hole and gently cover them.
-
Keep the crown (where all the leaves meet) just above the substrate.
-
Don’t bury the crown, or it may rot.
You can plant wendtii as:
-
A single specimen as a focal point, or
-
A group of several crowns to form a fuller bush over time.
Crypt Melt: The Classic Phase
Almost every aquarist meets crypt melt at some point.
What is crypt melt?
-
Leaves turn yellow, transparent, or brown
-
Many or all leaves fall off
-
It can look like the entire plant is dying
This often happens:
-
After planting in a new tank
-
After big changes to light, substrate, or water
-
After moving crypts or cutting roots heavily
What to Do
-
Don’t rush to throw the plant away.
-
Check the roots and crown:
-
If they are still firm and not smelly or mushy, the plant is alive.
-
-
Trim away fully melted leaves to prevent rot.
-
Keep conditions stable and give it time.
Often, after a few weeks, new leaves emerge that are adapted to your tank’s conditions. Wendtii is quite resilient once it decides your tank is “home”.
Growth and Trimming
Crypt wendtii is not a stem plant, so trimming is different.
How It Grows
-
New leaves rise from the center of the rosette (crown).
-
Over time, small side crowns can appear, forming a wider group.
-
In a mature tank, you can get a thick, bushy clump.
When and How to Trim
-
Remove old, damaged, or algae-covered leaves by cutting them near the base.
-
If the clump is too dense, you can gently pull out a few side crowns and replant them elsewhere.
-
Avoid uprooting and replanting the entire group repeatedly – crypts don’t like being disturbed.
Because growth is steady, not fast, any big trimming or uprooting will take some time to recover. Small, regular maintenance is easier.
Variants: Green, Brown, Tropica – What’s Different?
Their core care is the same. The differences are mostly in appearance.
Cryptocoryne wendtii ‘Green’
-
Leaves: Green, smoother surface
-
Look: Fresh, bright, classic jungle-green
-
Good for: Calmer, lighter layouts, “fresh” feeling midground
Cryptocoryne wendtii ‘Brown’
-
Leaves: Brownish to olive, sometimes reddish tones
-
Look: Natural, earthy, slightly darker
-
Good for: Adding contrast against green plants and sand
Cryptocoryne wendtii ‘Tropica’
-
Often has more textured or hammered leaves
-
Color: Green–brown mix, depending on light
-
Look: More “wild”, with variation on each leaf
You can mix them in one tank for a subtle variety, or use one type to keep the scape more unified.
Common Problems and Gentle Fixes
1. Plant Melts After Planting
Cause: Classic crypt melt, adaptation stress.
What to do:
-
Trim away dead leaves.
-
Don’t move or replant again and again.
-
Keep water changes moderate and stable.
-
Wait a few weeks for new leaves.
2. Leaves Full of Holes or Very Pale
Possible causes:
-
Nutrient deficiencies (especially potassium or nitrogen)
-
Very old leaves naturally aging
-
Damage from snails or fish in some cases
What to do:
-
Remove the worst leaves during maintenance.
-
Ensure you’re feeding the tank enough (fish food → waste → nutrients).
-
Consider a gentle liquid fertilizer and/or root tabs if substrate is very inert.
3. Algae on Leaves
Slow-growing leaves can easily become algae spots in an unbalanced tank.
Possible causes:
-
Too much light for current nutrient/CO₂ levels
-
Very long photoperiod
-
Organic waste building up
What to do:
-
Reduce light duration slightly.
-
Improve water change routine.
-
Gently wipe or remove the most affected leaves.
-
Add algae-eaters if compatible (snails, shrimp, small fish).
Shrimp and Fish Compatibility
Cryptocoryne wendtii is shrimp-safe and works well in community tanks.
Benefits:
-
Dense leaves offer hiding spots for shrimp and fry.
-
The root system helps stabilize substrate and support beneficial bacteria.
-
Broad leaves become surfaces for biofilm and micro-organisms.
Just avoid:
-
Strong chemical algae cures
-
Rough fish that dig heavily in the substrate and uproot plants
How I Like to Use Crypt Wendtii in Layouts
If you want to sketch where crypt wendtii, hardscape, and other plants will sit before you start planting, you can use this simple tool: Aquascape Layout Planner.
Some simple layout ideas:
-
As a midground bush in the center, with rocks or wood around it.
-
As a transition plant between lower carpets and taller stems or background plants.
-
Around the base of driftwood or stones, making the hardscape feel older and more “connected” to the substrate.
Green, Brown, and Tropica can be used to create layers of shades: lighter in front, darker behind, or mixed gently for a natural riverbank feeling.
Final Thoughts: A Steady Midground Companion
Cryptocoryne wendtii is not dramatic, but it’s extremely reliable once it settles.
It grows at a human-friendly speed – slow enough not to overwhelm you, fast enough that you can see progress over weeks and months.
If you like tanks that feel rooted, calm, and a little bit “forest-like”, this plant can quietly become the heart of your layout.
