Notes:

Rotala rotundifolia 'Red' is a popular and beginner-friendly stem plant known for its reddish-pink to deep red hues under optimal conditions. It’s adaptable and less demanding than many red plants, making it a favorite for both low-tech and high-tech setups (though reds intensify with CO₂ and strong lighting).

Tips for best coloration:

• Use highlight (without shading)
• Maintain lean water column nutrients (especially lower nitrates)
• Inject CO₂ for more compact and vivid growth
• Regular trimming encourages bushier appearance

Ideal for mid- to background in aquascapes, it’s often grouped in bunches for a vibrant red splash against green plants.
