Rotala rotundifolia problems — and how to fix them
Rotala rotundifolia (Rotala rotundifolia) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Stays green instead of pink/red
Colour is light-driven. Increase PAR and keep nitrate slightly lean; without high light it grows healthy but plain green.
Leggy stems with bare lower halves
Too little light or shading from above causes lower leaves to drop. Increase light, thin the canopy, and replant trimmed tops.
Tip stunting
Often a micronutrient or unstable-CO2 issue. Maintain steady CO2 and dose trace elements including iron and magnesium.
Overgrowth and crowding
Its speed means it quickly fills the tank and shades neighbours. Trim weekly and remove excess stems to keep the aquascape balanced.
