Cyperus species are widespread all over the tropics, but only a few of them are good underwater plants. Cyperus Helferi from Thailand is the first Cyperus species used in aquariums. It requires a relatively large amount of light, and CO2 addition and a rich nutrient substrate are recommended to promote growth. In aquariums with good water flow the plant sways beautifully in the current.
