Background
Picture its place. Understand its size.
Rotala macrandra brings broad red leaves and strong contrast. It remains demanding: Tropica recommends very good light, CO₂ and soft water for optimal development. Give it an open position in a carefully managed aquarium.
Tropica guide after roughly two months. “+” means the plant may exceed this height; it is not an adult maximum.

What it needs. And why.
Light
HighThis plant needs strong light at its position. Simply extending the lighting period does not make up for insufficient intensity.
CO₂
HighPlan for stable pressurised CO₂ injection and suitable circulation before choosing this plant.
Nutrition
Roots and leaves contribute to nutrition. Match nutrient additions to the substrate, water and observed growth rather than automatically combining fertilisers.

From the cup to your layout.
A few steps suited to this plant for a good start.
1Rinse off the growing medium
Gently remove the plant from its cup and rinse off the culture gel before placement.
2Divide gently
Prepare small healthy portions without crushing leaves, stems or roots.
3Plant in the substrate
Space portions so light and water can pass between them. Bury the roots while keeping rosette crowns exposed.
Pruning and ongoing care
Renew the group with healthy stem tips and avoid abrupt changes in conditions.
Understanding acclimatisation
An In-vitro cup contains young plants. Shape, colour and size can change after immersion. Watch new growth, remove deteriorating parts and keep conditions stable. Report plants damaged on arrival; acclimatisation does not explain every problem.
