Hornwort – Ceratophyllum demersum

Introduction
Hornwort (Ceratophyllum demersum) is a fast-growing, hardy aquatic plant that’s popular in freshwater aquariums. Known for its ability to thrive in various water conditions and its minimal care requirements, it makes an excellent addition to tanks of all sizes. Hornwort provides great benefits, such as natural filtration and oxygenation, while also offering a lush, green aesthetic for aquascapes.


1. Natural Habitat and Characteristics
Hornwort is native to North America, Asia, and Europe, typically found in slow-moving streams, ponds, and lakes. It grows entirely submerged, forming dense mats of slender, feathery green stems. This plant does not root in the substrate; instead, it floats or is anchored in the tank using weights or fine gravel.


2. Aquarium Setup

  • Tank Size: Suitable for all tank sizes, but works especially well in medium to large aquariums.
  • Substrate: Hornwort does not require substrate, as it is a floating plant. However, anchoring it to rocks or decorations with fishing line or weights can help keep it in place.
  • Lighting: Moderate to high lighting encourages lush growth, though it can tolerate low light.
  • CO₂ and Fertilization: While not strictly necessary, supplemental CO₂ and fertilizers (particularly micronutrients) can improve its growth, especially in tanks with high lighting.
  • Water Parameters:
    • Temperature: 59–86°F (15–30°C)
    • pH: 6.0–8.0
    • Hardness: Soft to hard (5–15 dGH)
  • Placement: This plant can be used as a floating plant or anchored to add texture and greenery to the mid or background of the aquarium.

3. Care and Maintenance

  • Trimming: Hornwort grows rapidly, and regular trimming is necessary to prevent it from overgrowing and blocking light from other plants.
  • Propagation: Hornwort propagates easily through fragmentation. Simply cut off a portion of the plant and replant or let it float freely.
  • Growth Rate: Fast-growing, especially in nutrient-rich water with good lighting.

4. Compatibility with Tank Inhabitants
Hornwort is a highly versatile plant, making it compatible with almost all freshwater fish, shrimp, and snails. Its dense growth provides hiding spots for fry and smaller species, and it can act as a refuge for timid fish. Avoid placing it in tanks with plant-eating fish, such as goldfish or large cichlids, as they may nibble on the plant.


5. Common Challenges and Tips

  • Floating: Hornwort is a floating plant by nature, and it can easily break loose from its anchorage. Use weights or small rocks to help keep it in place.
  • Clogging Filters: The fast growth of Hornwort can cause clogs in filters, especially when it breaks into pieces. Regular pruning and removing excess plant material can help prevent blockages.
  • Slow Growth in Low Light: If growth is slow, consider increasing light intensity or adding CO₂ supplementation to boost growth.

Conclusion
Hornwort is a fantastic plant for hobbyists looking for an easy-to-care-for, fast-growing aquarium plant. Its ability to thrive in a variety of conditions, coupled with its natural filtration properties, makes it ideal for tanks with high fish loads or new aquariums. Whether used as a floating plant or anchored, it adds beauty and function to any freshwater tank.
