About the Purple Cabomba
Purple Cabomba (Cabomba pulcherrima) is a delicate and visually striking aquatic plant known for its fine, feathery leaves and vibrant purple or reddish hues. It is a popular choice for background placement in aquascapes, adding a soft, flowing texture to the tank.
1. Light requirements: Requires moderate to high lighting to maintain its purple coloration and dense growth. In lower light conditions, it may become leggy, with less intense coloration.
2. Water parameters:
- Temperature: Prefers a range of 72 to 82Β°F (22 to 28Β°C).
- pH level: Grows best in slightly acidic to neutral water, with a pH range of 6.0 to 7.5.
- Hardness: Tolerates soft to moderately hard water.
3. Substrate and placement:
- Does not require a nutrient-rich substrate, as it absorbs nutrients primarily from the water column.
- Can be planted in the substrate or left floating. If planted, ensure the stems are gently anchored in fine-grain substrate to prevent damage.
4. Nutrients and CO2:
- Fertilization: Benefits from regular liquid fertilization, particularly with iron, to enhance its purple hues.
- CO2 supplementation: Strongly recommended to promote healthy, fast growth and vibrant coloration.
5. Pruning and maintenance:
- Grows rapidly under optimal conditions, so regular trimming is necessary to prevent overgrowth.
- Pruning encourages bushier growth and prevents lower portions of the plant from decaying due to shading.
- Remove any decaying leaves to maintain water quality.
6. Propagation:
- Propagates easily through stem cuttings. Simply cut a healthy portion of the stem and replant it into the substrate, where it will develop roots.
7. Special considerations:
- Can be sensitive to sudden water parameter changes, so stable conditions are ideal.
- Algae may grow on its fine leaves if nutrients and lighting are not well-balanced.
- Some herbivorous fish may nibble on it, so be cautious when housing with plant-eating species.
With proper lighting, CO2, and regular trimming, Purple Cabomba can be a stunning addition to an aquarium, providing movement, color contrast, and a natural, flowing aesthetic.
