Alternanthera reineckii 'Rosanervig', often referred to as the "Red Alternanthera" or "Rosanervig," is a vibrant aquatic plant popular in freshwater aquariums. It is a variety of Alternanthera reineckii, which is known for its striking appearance and suitability in aquascaping.

Here are some key characteristics and care tips for Alternanthera reineckii 'Rosanervig':

Appearance:

• The plant features pinkish-red leaves with a noticeable white or cream-colored central vein.
• The leaves can vary in color depending on the lighting and nutrient levels in the aquarium, ranging from deep red to pink and green hues.
• It grows in a bushy form and can reach heights of 12 to 24 inches (30 to 60 cm) in aquariums.

Care Requirements:

1. Light:

   • Requires moderate to high lighting to thrive and produce its vibrant colors. Too little light may cause the plant to lose its bright hues and appear more green.

2. Water Conditions:

   • Ideal temperature: 72-82°F (22-28°C).
   • pH: Preferably 6.0 to 7.5.
   • Soft to moderately hard water is best.

3. Fertilization:

   • It benefits from regular fertilization (especially micronutrients like iron) and will respond well to liquid fertilizers or root tabs. Nitrogen, potassium, and phosphorus are also important for healthy growth.

4. CO2:

   • CO2 injection can help promote optimal growth and vibrant colors, especially in tanks with high lighting.

5. Substrate:

   • A nutrient-rich substrate can aid growth, though it can also do well with just a regular aquarium gravel if supplemented with root tabs.

6. Maintenance:

   • It tends to grow fairly quickly under the right conditions, so regular pruning is necessary to prevent it from overtaking the aquarium.
   • It's often propagated by cuttings; trim the stems, and replant them in the substrate for new growth.
