Rotala Nanjenshan is a fine leaf plant that enjoys a co2 and nutrient rich environment. It has a beautiful red and purple tint that make it impressive to look at underwater. The way it pops with the green on those needle leaves is stunning. It does prefer a moderate to high lighting set-up. It's not for beginners but may be the best plant for Intermediate aquarium hobbyists to test their metal on a hard plant. It certainly is rewarding. Prefers around a 73 degree temp. I would rate this plant a 6 out of 10 in terms of difficulty.
