Cryptocoryne pontederiifolia is a popular and visually striking freshwater aquarium plant in the Cryptocoryne genus, prized for its tall, textured leaves. Here’s a detailed description:

General Description

• Type: Submerged aquatic plant

• Origin: Southeast Asia, especially Sri Lanka

• Size: Medium to large; typically 20–40 cm (8–16 inches) tall, with leaves that can grow longer under ideal conditions

• Leaves:

  • Shape: Narrow, lanceolate with pronounced rippled or wavy edges

  • Color: Dark green, sometimes with reddish or brownish tones in lower light or older leaves

  • Texture: Sturdy, slightly glossy, with a prominent midrib

  • Arrangement: Rosette form, with leaves growing outward and slightly upright

Aquarium Care

• Lighting: Low to moderate; adapts to different light conditions, though growth is faster under moderate light

• Substrate: Nutrient-rich substrate recommended; roots absorb nutrients efficiently

• CO₂ and Fertilization: Optional; grows without CO₂ but benefits from liquid fertilizers for faster, denser growth

• Temperature: 22–28°C (72–82°F)

• Water Parameters: Soft to moderately hard water, pH 6.0–7.5

• Special Notes: Like other Cryptocorynes, it may experience “Crypt melt” when first introduced to a new aquarium but will recover

Uses in Aquascaping

• Ideal for midground to background planting in aquariums

• Adds vertical texture and structure due to its tall, wavy leaves

• Forms dense clumps, providing shelter for shrimp, fry, and small fish

• Slow to moderate growth; can be trimmed to maintain shape and prevent overcrowding
