Hygrophila Corymbosa 'stricta'

Hygrophila corymbosa 'Stricta' is a popular aquatic plant known for its attractive, bushy growth and vibrant green leaves. It’s relatively easy to care for, making it suitable for both beginners and experienced aquarists. Here’s how to care for Hygrophila corymbosa 'Stricta' in an aquarium:

Lighting

• Moderate to High Lighting: This plant prefers moderate to high light levels for optimal growth. Low light may cause it to become leggy or lose its vibrant color.

2. Water Parameters

• Temperature: 22-28°C is ideal. It can tolerate a range of temperatures, but it thrives in the mid-20s (degree celsius).
• pH: 6.0 to 8.0. It can adapt to slightly acidic to neutral conditions.
• Water Hardness: Soft to moderately hard water (3-15 dGH) is preferred.

Substrate

• Nutrient-Rich Substrate: While Hygrophila corymbosa 'Stricta' can grow in a variety of substrates, a nutrient-rich substrate or aquasoil will support better growth and healthier plants. Root tabs can be used to provide additional nutrients.

CO2 and Fertilization

• CO2: While not strictly necessary, injecting CO2 can enhance growth and promote bushier foliage.
• Fertilization: Regular liquid fertilizers, especially those containing potassium and micronutrients, are beneficial. If using an inert substrate, root tabs can help provide nutrients directly to the roots.

Growth and Maintenance

• Growth Rate: Hygrophila corymbosa 'Stricta' has a relatively fast growth rate and can grow quite tall, often reaching heights of 30-60 cm (12-24 inches) or more.
• Pruning: Regular trimming is necessary to maintain its bushy appearance and prevent it from overshadowing smaller plants. Trim back excessive height and side shoots as needed.

Placement in Aquarium

• Midground to Background Plant: Due to its potential height, it is best placed in the midground or background of the aquarium. It can provide a lush backdrop for smaller foreground plants.

Propagation

• Cuttings: The plant propagates easily through cuttings. Simply cut a healthy stem below a node and replant it. It will root and continue to grow, effectively creating new plants.

Water Flow and Circulation

• Moderate Water Flow: Providing moderate water flow helps prevent debris from accumulating on the leaves and promotes healthy growth.

Algae Control

• Algae Prevention: To prevent algae growth on the leaves, maintain proper water quality, balance light and nutrient levels, and ensure regular water changes. Avoid excessive light duration, as this can promote algae growth.

Compatibility

• Community Tank Friendly: Hygrophila corymbosa 'Stricta' is generally compatible with most fish and invertebrate species. However, avoid placing it in tanks with heavy grazers that may eat the delicate leaves.

With the right care, Hygrophila corymbosa 'Stricta' will thrive and enhance your aquarium with its lush, vibrant foliage, making it a valuable addition to any planted tank.

An interesting fact about Hygrophila corymbosa 'Stricta' is that it can display a remarkable change in leaf shape and colour based on the conditions it is grown in. Under optimal lighting and nutrient conditions, its leaves tend to be narrow and more upright, while in lower light, the leaves may become broader and more sprawling. This adaptability not only makes it a versatile choice for aquascaping but also allows it to thrive in a range of aquarium setups, from low-tech to high-tech environments. Additionally, it can produce small, white flowers above the water surface when grown emersed, showcasing its versatility as both an aquatic and semi-aquatic plant.
