Rotala wallichii is one of the most visually delicate and striking of all aquarium stem plants, producing whorls of very fine, hair-like pink to magenta leaves around thin upright stems. Under ideal bright light and CO2 conditions the plant develops an almost luminous warm pink colour and an exceptionally fine, soft texture that is unlike virtually any other aquarium plant.

It is a demanding species requiring bright light and CO2 injection along with precise nutrient management for the compact, intensely coloured growth it is capable of. Without CO2 or under insufficient light the fine leaves deteriorate quickly and growth becomes sparse and green. Soft, slightly acidic water gives the best results, and iron-rich fertilisation is essential for sustaining the warm pink pigmentation.

Supplied as an established potted plant, Rotala wallichii suits aquariums from 50 litres upward managed by experienced hobbyists with bright lighting and CO2. When healthy, it is one of the most spectacular background plants in the planted aquarium hobby and rewards the effort involved in maintaining ideal conditions.
