Overview
Rotala Blood Red (Rotala sp. 'Blood Red') is a prized deep-red stem plant that holds its colour even under moderate light once established. It is a advanced-level aquarium plant, best suited to keepers able to provide good light and stable conditions.
This guide covers how to grow Rotala Blood Red 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 prized deep-red stem plant that holds its colour even under moderate light once established.
It is a medium grower used in the midground/background of the aquascape. Slower growth makes it tidy and low-maintenance, though it can collect algae if light is high and nutrients are low.
Lighting Requirements
Rotala Blood Red grows best under 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: Required. CO2 injection is strongly recommended for healthy, dense, colourful growth, and is really needed to get the best from this plant.
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 Blood Red in the midground/background. Plant small portions into the substrate, spacing them so they grow together over time.
Propagation
Replant trimmed tops; it stays compact and red with high light, CO2 and lean nitrogen dosing.
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.
