Rotala Macrandra

Rotala macrandra is one of the most spectacular red stem plants in the aquarium hobby, prized for its broad, delicate leaves and intense shades of pink, red, and crimson. Often considered the centerpiece of high-end aquascapes, this stunning plant adds unmatched color and elegance to Dutch-style and nature aquariums.

Under high lighting, nutrient-rich water, and CO₂ supplementation, Rotala macrandra develops its most vibrant coloration and compact growth. Stable water parameters and regular fertilization are key to maintaining its health and brilliant appearance.
