Rotala sp. "H'ra," also known as "H'ra" or "H'ra Red," is a popular aquatic plant among aquarists, particularly those interested in planted tanks. It is a variation of the Rotala rotundifolia plant with more vibrant, green leaves that develop a reddish hue under high lighting and specific water conditions.
H'ra is a relatively easy plant to grow and maintain, making it an excellent choice for beginners or those looking to add more color to their aquariums. It requires moderate to high lighting, and CO2 supplementation is recommended for optimal growth and coloration. H'ra can be propagated by cutting and replanting the stems, making it an excellent plant for aquascaping projects. It can also provide a hiding spot for small fish and shrimp.
