Cryptocoryne Wendtii

Overview

Cryptocoryne wendtii is the easy 'crypt' - a low rooted rosette in green, bronze or wine-red that, once it stops sulking, is one of the toughest plants in the hobby. Its trademark is 'crypt melt': it dissolves after any big change, then quietly regrows from the roots. (Cryptocoryne wendtii.)

Origin & Natural Habitat

Sri Lanka, on the beds and shaded banks of streams and rivers.

Appearance

Clumping rosettes of textured, wavy-edged leaves 10-20 cm tall; colour shifts from green to bronze-red with more light.

Why People Grow It - Qualities & Benefits

• Very hardy once settled
• Thrives in low light, no CO2
• Colour options from green to red
• Great low midground plant

Care

Light: Low to moderate; more light brings out red tones and keeps it compact.

Water: 22-28°C, pH 6.0-7.5, soft to moderately hard.

Substrate: Rooted feeder - nutrient substrate or root tabs; leave it undisturbed to settle.

CO₂ & feeding: Not needed; grows slowly and steadily without it.

Placement: Foreground to midground clumps.

Extra: ⚠️ Expect 'crypt melt' - the leaves may dissolve after planting or a big water change. Do NOT rip it out. The roots are fine and will push fresh, water-adapted leaves within weeks.

Propagation

Sends up runners with new plantlets around the parent; separate and replant once rooted.

Common Problems & Pests

Crypt melt (transition/instability); slow to establish. Otherwise nearly bulletproof.

Toxicity & Safety

Non-toxic to aquarium livestock; not known to be toxic to cats or dogs. Shrimp-safe.

Best Suited For

• Beginners (with patience for melt)
• Low-tech midground planting
• Red-tone colour without CO2
• Undisturbed established tanks

FAQ

All the leaves melted after I planted my crypt - did I kill it?

No. Crypt melt is normal after planting or big changes. Leave the roots in place; new submerged leaves regrow in a few weeks.

How do I get the red colour?

More light. In low light C. wendtii stays green; brighter light brings out the bronze and wine tones.
