Alternanthera Reineckii ‘Rosanervig’ is a striking red and pink stem plant known for its colourful leaves and contrasting light-coloured veins. Its vibrant foliage provides an excellent focal point in planted aquariums and works particularly well when placed against green plants.
The leaves can develop shades of pink, red, purple and bronze depending on lighting, nutrient availability and carbon dioxide levels. Stronger lighting and CO₂ supplementation generally help encourage more intense colouration and compact growth.
This variety is best suited to the midground or background of the aquarium. Regular trimming encourages branching and creates a fuller, bushier appearance. Healthy cuttings can be replanted to expand the group.
Alternanthera Reineckii ‘Rosanervig’ is suitable for experienced beginners through to advanced aquascapers and adds strong colour contrast to nature-style, Dutch-style and heavily planted aquariums.

It can survive without CO₂, but supplementation is recommended for stronger growth, improved colour and better leaf development.
Moderate to high lighting is preferred. Stronger lighting generally encourages more compact growth and deeper red or pink colouration.
It is best positioned in the midground or background, where its colourful leaves can contrast with green aquatic plants.
Cut healthy stems just above a leaf node and replant the cuttings into the substrate. The remaining stem can produce new side shoots.
Insufficient light, limited nutrients or inadequate CO₂ may cause weaker colouration. Ensure the aquarium has balanced fertilisation and suitable lighting.
It is manageable for beginners with some planted-aquarium experience, but consistent lighting, nutrients and CO₂ will produce the best results.
Using low lighting while expecting intense red colouration.
Failing to provide sufficient nutrients.
Allowing stems to grow too tall and become shaded.
Planting the stems too closely together.
Neglecting regular trimming.
Making sudden changes to lighting, CO₂ or fertilisation.
