Alternanthera Reineckii

Alternanthera Reineckii is one of the most popular red aquarium plants, admired for its vibrant crimson to deep burgundy leaves and striking contrast against green aquatic plants. Its broad, colorful foliage makes it an excellent focal point in the midground or background, adding depth and visual impact to any planted aquarium.

With medium to high lighting, nutrient-rich water, and CO₂ supplementation, Alternanthera Reineckii develops its most intense red coloration and compact growth. Regular trimming encourages branching, allowing it to form lush, bushy groups that are perfect for Dutch-style and nature aquascapes.

While it benefits from stable water conditions and good fertilization, this beautiful stem plant is well worth the effort, rewarding aquascapers with stunning color throughout the aquarium.
