Growing Conditions

☀️

Sun: Moderate lighting: 2-3 watts per gallon or 40-60 PAR; benefits from 8-10 hours of light daily

💧

Water: Prefers cool to warm water (72-82°F / 22-28°C); adapts to soft to moderately hard water; benefits from gentle water circulation but tolerant of still conditions

📏

Spacing: 4-6 inches between plantlets for optimal density without overcrowding inches

📅

Days to maturity: 60-90 days to establish and begin producing runners

🌱

Planting depth: Plant base of plant at substrate level; do not bury the crown; runners should be pinned or weighted to substrate

Soil

Type: Nutrient-rich aquarium substrate (sand, fine gravel, or specialized planted tank substrate)

pH: 6.0-7.5

Amendments:

Liquid fertilizers (nitrogen, phosphorus, potassium) Trace elements (iron, boron, manganese) CO2 supplementation (optional but beneficial)

Growth Stages

Acclimation

2-4 weeks

Plant shows mild leaf melting or color fading as it adjusts to aquarium conditions

Maintain stable water parameters; reduce light intensity slightly during first 2-3 weeks; avoid major water changes

Establishment

3-6 weeks

New growth emerges; leaves stabilize in color; root system develops in substrate

Maintain consistent fertilization schedule; ensure gentle water flow; light can be gradually increased

Vegetative Growth

4-8 weeks

Plant develops multiple leaves and produces side shoots and runners from the base

Fertilize regularly; prune runners as needed to direct growth; remove older leaves to encourage bushier development

Propagation

Ongoing

Runners extend with baby plantlets forming at nodes; original plant continues producing new foliage

Pin runners to substrate or remove and replant separately; fertilize to support multiple growing points

Mature Colony

Indefinite with proper care

Dense carpet or clump forms with numerous plantlets of varying ages; leaves may darken or redden with high light

Thin out overcrowded areas; remove dead leaves promptly; maintain fertilizer and CO2 for sustained color and vigor

Companion Planting

Plan your garden →

Plant with:

Echinodorus tenellus Hemianthus callitrichoides Anubias nana Eleocharis mini Riccia fluitans Ludwigia repens

Avoid planting near:

Allelopathic stem plants (some Ludwigia species in very dense setups) Aggressive uproot-prone plants (large Echinodorus)

Common Pests

Reduce lighting duration; increase water change frequency; add algae-eating fish (Amano shrimp, plecos); consider algaecide for severe cases
Increase CO2 and fertilizer; reduce nutrient-to-light ratio; manual removal; use SAE (Siamese Algae Eater) or Excel product
Manual removal; reduce feeding of fish; introduce snail-eating fish or shrimp; quarantine new plants
Improve water circulation; reduce organic debris; perform 25-30% water changes; lower temperature slightly; quarantine affected plant
Increase fertilizer dose; add trace elements; ensure adequate lighting and CO2; check water parameters

Uses

🌿

Foreground Carpet Plant

Aquascaping

Cryptocoryne wendtii 'Compact' is a classic choice for creating low, dense foreground plantings in nature aquascapes and Dutch-style tanks. Its compact growth habit and slow spread make it perfect for framing larger centerpiece plants. [source]

🦋

Fish & Shrimp Habitat

Wildlife

The dense leaf structure provides shelter and grazing surfaces for dwarf shrimp, small fish, and fry. It also offers biofilm-growing habitat that invertebrates depend on for food. [source]

🏠

Low-Maintenance Aquatic Greenery

Household

Cryptocoryne wendtii 'Compact' is remarkably tolerant of varied conditions and low light, making it ideal for beginners or low-tech setups without CO2 injection. It thrives with just basic fertilization and moderate lighting. [source]

Harvest Tips

Not a harvest plant. Propagate by removing rooted runners and replanting 4-6 inches away; trim older leaf stems to encourage bushier side shoots; remove dead or melting leaves promptly to prevent decay

Fun Facts

🌱 Cryptocoryne wendtii undergoes 'crypt melt'—a stress response where leaves melt away when moved to a new aquarium, but the plant almost always regenerates from the rhizome within weeks.
🌱 The 'Compact' cultivar was selected and popularized by European aquarists specifically for its diminutive size, making it one of the smallest Cryptocoryne species suitable for nano aquariums.
🌱 In its native Sri Lankan habitats, Cryptocoryne species produce spathe-like flowers above water; in aquariums, flowering is rare but occasionally occurs if the plant is left partially emersed.
