Rotala Indica 'Bonsai' is a rare and hard to find plant, not to be confused with the common Rotala Indica.  This plant grows much slower compared to other stem plants and may be suitable for smaller tanks.  This plant is considered harder to keep and not suitable for beginners.  It often melts when planted submerged so it helps to grow it emersed first 
Under high lighting, CO2 and the addition of fertilizers, the tips of the stems will develop a reddish orange hue.
