Bio - this beautiful Aquarium plant is the best choice for almost any aquarium for lots of reasons but mostly because of its beautiful long, slender leaves that can even turn the loveliest shade of red. It is also very hardy for such a little delicate stemmed plant, It has grown in so many bad conditions for me, ive had it grow successfully in a 1 gallon, unheated tank. they help so much for quality, but don't depend on these for ammonia removers as they won't do the full job. From having this plant in my tank for so long I have found that it adds a layered look to the tank, it looks spectacular in the back round or mid ground for these specific reasons. If you can provide these every few requirements then you should definitely get this nice little plant here
R. Indica and R. Rotundifolia have both been classified for a long time, however the real R. Indica has only been available to the hobby for a couple years. Previously R. Rotundifolia was often sold as R. Indica, when they are 2 distinct species.
I'll provide this link for comparing the two species.
