Cryptocoryne Walkeri care guide
Cryptocoryne Walkeri (Cryptocoryne walkeri) — low light, 22-28 °C, pH 6-7.5, no CO2.
Overview
Cryptocoryne Walkeri (Cryptocoryne walkeri) is a broad-leaved plant of the family Araceae, grown as an aquarium plant. Compact crypt with olive-green leaves and reddish undersides. Shallow root system makes it suitable for shallow substrate beds. Reliable, slow-growing, and tolerant of varied parameters.
Taxonomy
- Family: Araceae
- Genus: Cryptocoryne
- Scientific name: Cryptocoryne walkeri
- Common synonyms: Crypt Walkeri
Habitat
Cryptocoryne species inhabit slow-flowing forest streams, peat-swamp creeks and seasonally flooded lowlands across South and South-East Asia. Most grow rooted in soft mineral or organic sediments under partial shade. In the Aquairi knowledge base this species is recorded from Sri Lanka.
Growth requirements
- Lighting: low
- CO2: not required
- Temperature: 22-28 °C (72-82 °F)
- pH: 6-7.5
- GH: 4-14 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 20 cm
- Growth rate: slow
- Nutrient demand: low
- Recommended placement: midground
Placement
In aquascapes this plant suits the midground. It is planted into a nutrient-rich substrate; emersed-grown stock often melts after submersion and regrows submersed leaves within weeks. Stable parameters minimise repeated melt.
Propagation
This species is spreads vegetatively by runners that form daughter plants on the substrate; clumps are divided once the colony has filled the area.
Common issues
Sudden parameter shifts, particularly temperature drops or large water changes, trigger so-called Crypt melt in which existing leaves dissolve while the rhizome regrows new ones; stable conditions prevent repeat events.
