Cryptocoryne lutea is a popular freshwater aquarium plant from the Cryptocoryne genus, known for its compact size and ease of care. Here’s a detailed description:

General Description

  • Texture: Soft, flexible, with a slightly glossy surface

  • Arrangement: Rosette form, with new leaves emerging from a central crown

Aquarium Care

• Lighting: Low to moderate; adaptable to various lighting conditions

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

Uses in Aquascaping
