Rotala macrandra ‘Japan’ is a magnificent aquarium plant, but unfortunately, it is very demanding. This variant is a little easier to grow and develops better coloration. It needs very good light to develop its beautiful red shades, just like CO2 addition and soft water are vital to ensure optimal growth.
Cut the longest stems 5-10 cm from the ground and replant them in the group.
