Description
Overview: Rotala Vietnam is a stunning geographical variant of the common Rotala rotundifolia. It is characterized by significantly thinner, needle-like leaves and a more intense golden-to-reddish hue. Unlike the standard variety, Rotala Vietnam is more demanding, requiring high light and consistent CO2 supplementation to maintain its delicate leaf structure and prevent the lower stems from losing leaves. It is a favorite for Nature Style aquascapes where fine textures are desired.
