Overview
Rotala Rotundifolia (Rotala rotundifolia) is a hugely popular bushy stem plant that turns from green to pink-orange under strong light. It is a intermediate-level aquarium plant, best suited to keepers able to provide good light and stable conditions.
This guide covers how to grow Rotala Rotundifolia successfully - its appearance and growth habit, lighting needs, whether it needs CO2, fertilising, planting and placement, propagation, and the common problems to avoid.
Appearance & Growth Habit
A hugely popular bushy stem plant that turns from green to pink-orange under strong light.
It is a fast grower used in the background of the aquascape. Fast growth means regular trimming, but it also makes the plant a powerful nutrient sponge that helps starve out algae.
Lighting Requirements
Rotala Rotundifolia grows best under medium to high lighting. It needs strong, even light reaching its leaves, so use a good planted-tank LED.
Run lights on a timer for about 6-8 hours a day. Longer photoperiods usually feed algae rather than plants, so increase duration cautiously and watch for any green film.
CO2 & Fertilisation
CO2: Recommended. CO2 is recommended for the best results, though patient keepers can grow it more slowly without it.
Dose a balanced liquid fertiliser (such as API Leaf Zone) for water-column nutrients, and add root tabs beneath heavy root-feeders. Yellowing, holes or stunted leaves usually signal a nutrient deficiency, not disease.
Planting & Placement
Plant or attach Rotala Rotundifolia in the background. Plant small portions into the substrate, spacing them so they grow together over time.
Propagation
Trim the tops and replant the cuttings; each cut stem branches and bushes out.
Sharing trimmings is part of the fun of the hobby - one healthy plant can fill a tank and stock several more over time.
Common Problems
The most common issue is algae on the leaves, which points to too much light, too few nutrients or weak flow rather than a fault with the plant. Melting (leaves dissolving) after planting is normal as it converts to underwater growth - keep conditions stable and new growth follows.
Keep light, CO2 and fertilisation consistent, remove dying leaves promptly, and avoid burying the crown or rhizome of plants that grow from one.
