🔍 Overview

• Common Name: Thai Hygrophila

• Scientific Name: Hygrophila corymbosa 'Thailand'

• Type: Stem plant

• Origin: Cultivar, likely from Southeast Asia

• Growth Rate: Fast

• Placement: Midground to background

---

💡 Lighting

• Moderate to High Light

  • Encourages vibrant coloration and compact growth

  • Low light leads to pale, stretched-out stems and leaf drop on lower parts

Under strong light, leaves may develop a reddish or bronze tint.

---

🧪 Water Parameters

• Temperature: 72–82°F (22–28°C)

• pH: 6.5–7.5

• Hardness: Soft to moderately hard water

---

🌱 Substrate & Fertilization

• Substrate: Nutrient-rich (aqua soil is ideal)

• Fertilization:

  • Liquid Fertilizer: Regularly dose macros and micros

  • Root Tabs: Helpful if planted in inert substrate

It’s a hungry plant—make sure it gets enough iron and micronutrients.

---

✂️ Trimming & Propagation

• Trimming: Regularly prune to prevent overcrowding and promote bushiness

• Propagation: Cut stems and replant tops directly into the substrate

Frequent trimming encourages side shoots and thicker growth.

📐 Tank Placement

• Ideal For: Midground in large tanks, background in smaller tanks

• Layout Tip: Plant in small groups with space between stems for light penetration and water circulation

---

🐠 Compatibility

• Safe for Fish and Inverts: Yes

• Aquarium Benefits:

  • Fast grower—great for soaking up excess nutrients

  • Helps prevent algae by competing for nutrients

---

⚠️ Common Issues

• Melting after planting: Common in new tanks or after big parameter shifts—will bounce back

• Lower leaves dropping: Often due to low light or lack of nutrients

• Stunted new growth: May signal micronutrient deficiency, especially iron

---

🌸 Bonus Features

• If grown emersed (above water), it can flower with beautiful lilac or violet blooms

• Excellent choice for open-top aquariums or paludariums
