Rotala sp. ‘Nanjenshan’

Rotala sp. ‘Nanjenshan’ is a delicate and attractive aquarium stem plant originating from Taiwan, known for its fine, needle-like light green leaves arranged densely along slender stems. Its graceful, bushy growth form adds texture and movement to aquascapes.

Growing to 30-50 cm tall, it is ideal for background placement in small tanks or midground planting in larger aquariums. Its soft light green colour contrasts beautifully with red plants and dark hardscape, enhancing layout depth and balance.

Rotala ‘Nanjenshan’ thrives under medium to high lighting with CO₂ injection, which promotes compact growth and prevents legginess. Regular fertilisation with micronutrients is essential to maintain healthy vibrant foliage.

It has a fast growth rate under optimal conditions and requires frequent trimming to encourage bushier tops and prevent shading of surrounding plants. Propagation is easy via stem cuttings replanted into the substrate.
