Echinodorus opacus is a remarkable, beautiful swordplant wild type that originates from Paraná state in southeastern Brazil, occurring in fast-flowing rivers. Described as a species by Karel Rataj in 1970, it is likely a natural hybrid from the Echinodorus grandiflorus species group. There are different plants under that name, however our plant is a small form that is already cultivated since the 1970's as Echinodorus opacus. Due to its low propagation rate it is still a rarity. Only recently the name addition "Rataj" is used to designate this small E. opacus form.
Very different from the many big, fast-growing Echinodorus types, this plant grows slow and hardly flowers. It developes a creeping rhizome and hard, stiff, dark green leaves with ovate blade. It is particularly attractive through its light nervature that contrasts with the darker leaf tissue.
Echinodorus opacus "Rataj" is not really demanding and is content with medium light intensity, however it benefits much from nutrient-rich substrate and CO2 supply. The temperatur may drop below 20 °C, corresponding to the subtropical climate in southern Brazil with already quite cool winters. With the growth of the rhizome, the leaf rosette shifts slowly on the ground. Long rhizomes can be cut into pieces for propagation. Side shoots will grow from buds on the rhizome parts.
This rare Echinodorus wild type is a special gem in aquariums, looking best as an adccent plant in the midground, in tall tanks also in the foreground. Old, broad specimens with many leaves are especially attractive. This plant should also be interesting for naturally designed aquariums, imitating a river biotope with pebbles and boulders.
Please be aware that the submerse form of this plant could contain snails and other invertebrates.

Special mosses, particular stem plants, hard-to-come-by ferns or very rare forms of the genus Bucephalandra are only a few of the plants we are proud to offer.
Really beautiful plant which deserves best place in your tank. I received one in perfect condition, with huge root system. It adapted perfectly in my tank and soon started to grow. (read more)

Die Pflanze gibt es seit den siebziger Jahren, damals wie heute stellt sie immer noch eine Rarität dar. Sie wächst sehr gut in Soil u. CO2 reichen Wasser, saures Milieu und nicht beschatteten Standort. Wurzeldünger, wie Tropica Tabs, damit sie sich kräftig entwickelt. Kühlung in der Sommerzeit, dass die Temperatur kühl bleibt für die Art aus dem kühleren südlichen Südamerika.
Die Pflanze kam in super Qualität an. Und so viele Blätter...Wow! Das hatte ich so nicht erwartet. Der langsame Wuchs kann ich nicht bestätigen. (read more)
Die Pflanze kam in super Qualität an. Und so viele Blätter...Wow! Das hatte ich so nicht erwartet. Der langsame Wuchs kann ich nicht bestätigen. Sie wächst bei mir in einem separaten "Aquasabi Plant Pod" gefüllt mit ADA Soil Amazonia Powder nahe der Wasseroberfläche in starker Strömung bei 12 Sündiger HQI Beleuchtung (ADA 150 Watt Green). Das Weiche Wasser KH 2-3 GH 5-6 wird mit Aqua Rebell Produkten gedüngt (nach Flowgrow Dünge Rechner). Einziger negativer Punkt ist der starke Auftrieb der Pflanze. Musste sie mit einem Gummiband um den Pod fixieren.
