Rotala macrandra

Rotala macrandra is an unusually beautiful aquarium plant, but unfortunately it makes such big demands that it only thrives in a few aquariums. It needs very good light to develop its beautiful red colour, and CO2 addition and soft water are vital to ensure reasonable growth. It is most beautiful in groups, but do not plant individual shoots too close because this will prevent light reaching the lower leaves. To ensure good colour there must be sufficient micro-nutrients in the water.
