Echinodorus Amazonian one of the most popular and widely distributed representatives of the genus, the prevalence of which in the amateur collection is explained by the attractive appearance, dimensions and simplicity of breeding acceptable to most indoor ponds.
In nature, it inhabits the stagnant and slowly flowing waters of the Amazon. It develops best on the ground with a layer of 5-8 cm, consisting of a mixture of coarse sand and fine gravel.
In small aquariums, Echinodorus Amazonian is planted alone, in spacious ones they are equipped with loose groups of 5-7 outlets. Prefers a temperature of 22-26 degrees with a neutral reaction and a hardness of 6-12 ° dGH. Satisfied with moderate lighting.
Ekhinodorus vegetatively propagated by daughter plants, abundantly formed on the peduncles.
The Latin name is echinodorus amazonicus. Large specimens reach a height of 35-40 cm and occupy a large area. However, contain echinodorus can be in a small aquarium.
Grows evenly regardless of the season.
The temperature of the water at which the Amazonian echinodorus normally develops can vary widely – from 16 to 28 ° C, however, it is not worth keeping this plant constantly at a low temperature. Water hardness can also vary widely. Unlike most Echinodoruses, this member of the genus grows very well in both low acid and alkaline water.
Prefers fresh, regularly replaced water.
For lighting, “Amazon” does not make high demands. If the aquarium is located at the side wall near the window, natural light will be sufficient for Echinodorus.
The plant withstands long-term shading, but the color of the leaves may fade. The nature of the lighting does not matter much. For artificial lighting incandescent or fluorescent lamps are quite suitable.
You can contain echinodorus in low light (the power of fluorescent lamps from 0.25 W per 1 liter of water), but the plant develops better in brighter light. Duration of daylight should be about 12 hours.
The substrate can be any, layer thickness – 5-7 cm. The soil must be sufficiently nutritious, moderately or well silted. To power the plant is usually enough natural silting of the soil.
Its highly developed root system needs a sufficiently thick layer of soil, therefore, when a layer of soil is less than 5 cm, Amazonian Echinodorus develops poorly.
Amazonian Echinodorus usually does not need special mineral dressing. If the water in the aquarium is too soft, Ekhinodorus may develop symptoms of mineral starvation.
To eliminate the symptoms, it is enough to feed the plant with complex mineral fertilizers, adding trace elements to the water in small portions, not more than 1-2 g per 100 l every 5-7 days.
