Hygrophila pinnatifida – Pinnatifida Hygro
Hygrophila pinnatifida is a striking stem plant known for its deeply lobed, fern-like leaves and compact, upright growth. Native to India, it is highly prized in aquascaping for its dramatic texture, vibrant green color, and ability to form dense midground clusters. Its unique leaf shape adds depth and contrast, making it a favorite in both high-tech and low-tech planted aquariums.
Lighting
Moderate to High Lighting: Strong light encourages compact growth, vibrant coloration, and fuller leaf development. Under low light, the plant may become leggy and lose its distinctive leaf shape.
Water Parameters
Temperature: 22–28 °C; prefers stable, moderate conditions.
pH: 6.0–7.5, slightly acidic to neutral water is ideal.
Water Hardness: Soft to moderately hard water (2–12 dGH) supports optimal growth.
Substrate
Nutrient-Rich Substrate: Thrives in aquasoil or enriched substrates; root tabs help if using inert gravel or sand.
Depth: 5–7.5 cm (2–3 inches) substrate depth allows healthy root anchoring.
CO₂ and Fertilization
CO₂: Recommended for faster growth, fuller foliage, and denser midground coverage.
Fertilization: Regular dosing of macronutrients and micronutrients, particularly iron, ensures strong growth and rich green coloration.
Growth and Maintenance
Growth Rate: Moderate; produces multiple side shoots that can be trimmed to maintain bushy appearance.
Pruning: Regular trimming of stems promotes dense, compact clusters and prevents legginess.
Placement in Aquarium
Midground: Ideal for adding height, texture, and contrast behind foreground carpets and in front of background plants.
Propagation
Stem Cuttings: Trim healthy stems and replant in substrate; new roots develop quickly under proper conditions.
Water Flow and Circulation
Moderate Flow: Helps maintain leaf health and prevents debris accumulation.
Algae Control
Prevention: Balanced light, nutrients, and CO₂ minimize algae growth on delicate leaves. Avoid excessive light without adequate nutrient supplementation.
Compatibility
Community Tank Friendly: Safe with most peaceful fish and invertebrates. Avoid large or digging species that may damage delicate leaves.
With proper care, Hygrophila pinnatifida will create a dense, textured midground display, adding depth and visual interest to your aquascape.
Interesting Fact: The deeply lobed, fern-like leaves of Hygrophila pinnatifida not only enhance aesthetic appeal but also provide natural hiding spaces for small fish and invertebrates. Its adaptability to different lighting and nutrient conditions makes it a versatile and striking addition to both low-tech and high-tech planted tanks.
