Norway sturgeon (Heteranthera zosterifolia) – aquarium plant Pontederiev family (pontederiaceae).
Distribution area Meteoride are the tropics of South America.
Norway sturgeon gentle aquarium plant with a long stem, has light green narrow leaves. The stem can grow up to 40-50 cm, but the most optimal contain it in aquarium with a low water level, this is due to the fact that in high aquariums the lower leaves of the plant fall away and Geterantera loses its appeal. To bring the plant in order, you have to pick off the top and transplant it into the ground.
This is an unpretentious plant, so it is widespread among aquarists. Grows evenly almost throughout the year.. Norway sturgeon feels particularly comfortable at – 22-26 ° C, but it can be maintained at a temperature of 20 ° C.
At lower temperatures, growth slows down. To maintain an attractive plant appearance, it must be contained in soft water with a low level of acidity.
With an increase in the level of water hardness, the process of dying off of old leaves is observed, only its upper part remains. If you put the stellate to Goetheranter in the old aquarium water with the addition of a small amount of peat, there will be an active growth. In such conditions, the replacement of water plant is not required.
Lighting, in which the plant grows, should be bright, otherwise larva geterantera strongly drawn out, and its leaflets become smaller. Lighting is suitable for any, both natural and artificial. If you have placed the plant in a deep aquarium, be sure to make side lighting.
The length of the light day depends on the intensity of illumination; the brighter the light, the shorter the light day can be. In the neighbors of this plant is better to choose light-loving hydrophytes. To the nature of the soil geterantera not picky, because it takes the nutrients straight from the water.
Gerantera Norway does not require special mineral dressing.
Norway sturgeon easily propagated by grafting. To do this, the tip or well-developed lateral shoot is separated from the mother plant and left to float in the water until the roots are formed.
In this condition Norway sturgeon grows a little slower, but at the same time retains its shape.
