Alternanthera Reineckii 'Rosanervig', also known as the Pink Vein Alternanthera, is a popular aquatic plant among aquarium enthusiasts. Its vibrant pink and red hues make it a stunning addition to any aquarium. However, to ensure its health and longevity, proper care is essential. In this care guide, we will explore the key factors to consider when caring for Alternanthera Reineckii 'Rosanervig'.

Lighting Requirements

Alternanthera Reineckii 'Rosanervig' is a demanding plant when it comes to lighting. It requires high-intensity lighting to thrive. Aim for at least 3 watts per gallon of full-spectrum lighting. LED lights are highly recommended as they provide the necessary intensity and spectrum for optimal growth.

Water Parameters

Maintaining the right water parameters is crucial for the health of Alternanthera Reineckii 'Rosanervig'. It thrives in slightly acidic to neutral water with a pH range of 6.0 to 7.0. The water temperature should be kept between 72°F and 82°F (22°C to 28°C). Additionally, it requires soft to moderately hard water with a hardness level of 2 to 10 dKH.

Substrate and Fertilization

A nutrient-rich substrate is essential for the proper growth of Alternanthera Reineckii 'Rosanervig'. Use a substrate specifically designed for planted aquariums, as it provides the necessary nutrients for the plants. Additionally, supplement the substrate with root tabs or liquid fertilizers rich in iron and micronutrients to promote vibrant coloration.

CO2 Injection

While not mandatory, injecting CO2 into the aquarium can greatly enhance the growth and coloration of Alternanthera Reineckii 'Rosanervig'. CO2 supplementation helps the plant photosynthesize more efficiently, resulting in faster growth and more intense colors. Aim for a CO2 concentration of 20 to 30 ppm for optimal results.

Pruning and Maintenance

Regular pruning is necessary to maintain the shape and health of Alternanthera Reineckii 'Rosanervig'. Trim any yellow or decaying leaves to prevent them from affecting the overall health of the plant. Additionally, remove any algae that may accumulate on the leaves or substrate to ensure the plant receives maximum light and nutrients.


When selecting tankmates for your aquarium, it's important to consider the compatibility of Alternanthera Reineckii 'Rosanervig'. Avoid keeping it with herbivorous fish or invertebrates that may nibble on the leaves. Instead, opt for peaceful community fish that won't disturb the plant.


With its striking pink and red hues, Alternanthera Reineckii 'Rosanervig' is a captivating addition to any aquarium. By providing it with the right lighting, water parameters, substrate, and maintenance, you can ensure its vibrant colors and healthy growth.
