About
Rotala indica (the 'true' form) is a stem plant in the family Lythraceae, native to Asia. Also known as a rice-paddy weed, in the aquarium it is loved for its charming form of rounded, oppositely arranged leaves. Historically, plants traded under the name 'Rotala indica' have included other species (such as Ammannia), so the 'true' qualifier denotes the genuine Rotala indica. Under ample lighting, CO2, and nutrients, the leaf tips and stems take on reddish tones, adding soft color to the background when grown in groups. Growth is relatively fast and it is easily propagated by trimming and replanting. Manageable even for beginners depending on conditions, achieving clean coloration requires care, so it suits intermediate hobbyists. It prefers soft, slightly acidic to neutral water.
