Cryptocoryne wendtii “brown” is a beautiful brown variety of Cryptocoryne wendtii. It is a mistake to believe that Cryptocorynes require soft water. In large parts of Sri Lanka the water is hard, so Sri Lanka Cryptocorynes are almost all suitable for hard European water. If the plant is affected by the so-called ”cryptocoryne disease”, do not remove it from the aquarium because a few weeks later it will produce new shoots. See other Cryptocorynes for further information.
