Cabomba caroliniana, commonly known as Carolina fanwort, is a submerged aquatic plant native to freshwater regions of South and Central America. It has become popular in the aquarium trade due to its attractive feathery leaves and ability to provide oxygen in aquatic environments. However, it is also considered an invasive species in some regions, such as Australia and parts of Europe, where it can outcompete native flora.

Origin

• Native Regions: Southeastern South America (southern Brazil, Paraguay, Uruguay, northeastern Argentina) and the eastern and western coasts of the United States.
• Invasive Status: It has spread globally and is now regarded as an invasive species in various locations, including Australia and parts of Europe13.

Light Conditions

Cabomba caroliniana requires bright lighting to thrive. Insufficient light can lead to slow growth and decay of lower leaves. For optimal health, a full-spectrum aquarium light that mimics natural sunlight is recommended. This ensures the plant maintains its vibrant green color and supports its photosynthetic needs13.

Water Conditions

• Temperature: Ideal range is between 22°C to 26°C (71.6°F to 78.8°F).
• pH Level: Recommended pH is between 6.5 to 7.2.
• Water Hardness: Should be maintained between 4 to 12°dGH (71.43 to 214.29 ppm).
• Habitat: Prefers slow-moving or stagnant waters with a substrate that can support its roots123.

How to Plant

1. Preparation: Select healthy stems for propagation. Cuttings should be taken just below a node.
2. Removing Leaves: Trim any leaves from the lower part of the cutting to prevent decay once planted.
3. Planting:
   • Insert the bare stem into the substrate, ensuring it is secure but not crushed.
   • Group several cuttings together for a fuller appearance.
5. Care Post-Planting: Provide bright lighting and monitor water conditions regularly to encourage rapid root establishment and growth123.

• Cabomba caroliniana is moderately easy to care for, making it suitable for aquarists with some experience. Regular attention to lighting and water quality will help maintain its health and beauty in an aquarium setting.
