In nature, dark / matte Echinodorus grows in Brazilian rivers. For the first time this plant was discovered in the distant 1970. Due to the fact that this type of plant is difficult to grow it is rarely found in the home collections of aquarists.
If all the necessary conditions are met, ECHINODORUS DARK can reach 35 cm. Echinodorus develops very slowly, which requires constant feeding. To get a beautiful bush you need to make periodically clay under the root system.
Acclimatization to a new habitat will be much faster if the plant is planted away from other bushes that may interfere with it.
Echinodorus dark – this is an aquarium plant with a short rhizome, in good conditions its height can reach 35 cm. The petiole generally has a length of 12 to 23 cm and a rounded shape in cross section. Leaf plate can be modified from ovoid to narrowly ovoid shape.
All leaves are characterized by a surprisingly hard surface, which can be dark green or light green. The top of the bush is sharp, acicular.
The base of young plants is heart-shaped. The leaf has 5-7 veins, the transparent pattern is completely absent.

Water. Keep Echinodorus small-color can be in moderately warm and tropical aquariums. The temperature of 20 – 28 ° C is quite satisfied with this plant.
A short-term decrease in temperature to 16 – 18 ° C does not harm it. Water can be from very soft (1 – 2 °) to hard (20 ° and even more). In neutral and slightly alkaline water, the plant feels somewhat better, but it also grows quite satisfactorily in an acidic environment.
Water changes should be carried out regularly, 3-4 times a month. In old sour water, Echinodorus slows growth and begins to shed old leaves.
By lighting, the small-color echinodorus is not very demanding, but with a lack of light, the leaves of the plant lose their interesting color and become ordinary – green. Natural light is very useful to this Echinodorus. Any fluorescent and incandescent lamps are suitable for artificial lighting.
Lighting should be selected individually depending on the location of the light sources, their combination and the presence of other plants in the aquarium. With a day length of 14 hours or more, the plant can form elliptical leaves on long cuttings.
Ground for Echinodorus should be well silted, rich in nutrients. In the new soil for the roots, it is advisable to make additional dressing in the form of clay or a mixture of clay and peat.
In the old aquarium, the natural silting of the soil is enough for feeding the plant. The nature of the substrate has virtually no effect on the growth of echinodorus.
Its powerful root system requires a fairly thick layer of soil. If a substrate consisting of fine fractions is used, the soil layer should be at least 5–7 cm thick.
If the substrate particles are larger, the soil layer may be thicker.
Mineral dressing with sufficiently nutritious soil and regular water changes are not required.
Under aquarium conditions, the small-color echinodorus reproduces vegetatively. A lot of daughter plants form on its floral arrows, which, after the appearance of 4-5 leaves and the root system, can be separated and transplanted to a new place.
Reproduction under favorable conditions is possible throughout the year.
Seed propagation of this echinodorus is difficult for an amateur to achieve.
