Elodieus freshwater plant, or anaccharis, is quite unpretentious, it grows quickly under any conditions. For this it is called water plague.
Able to survive even in the inept hands of novice aquarists.
Elodea is very common as an aquarium plant. It is able to grow without soil, which is convenient for setting up a temporary aquarium, for the delivery of fish and other similar cases.
The plant came from Canada and the United States. In Europe, the Elodieus happened to be in the 19th century by chance.
Here it spread quickly, filling numerous ponds. Therefore, its people called it water plague.
In other countries, it is considered an invasive species. Very often it can be found in the Russian area, also in the Moscow region.
Facts are known when impassable thickets of this plant did not allow free fishing and navigation.
At the same time, elodeya is used as a useful fertilizer and as food for pigs and ducks, due to the speed of its growth. In the presence of bright light, it turns into a large green mass.
Elodea also accumulates in itself deposits of metals, as well as radionuclides, which make it suitable for environmental research. In the school and student programs there is a section where the plant cell is studied, the movement of cytoplasm and chloroplasts. The leaf of elodea is an object for this study.
The plant is not picky to the structure of water, can grow in soft and hard water. Difficulty can occur only when it is transferred from one water to another, but this happens infrequently.
A large number of species of Elodea like cool water with a temperature in the range of 16-24 ° C. If the temperature is higher, the plant becomes worse. If the aquarium is tropical, then 28-30 ° C will not work anymore.
The plant looks like brittle, long, curly shoots. Small parts of the shoot can easily flow away with the flow – in this way the plant spreads. Thin long roots are produced, with the help of which it is rooted and fixed in the soil.
Reproduction occurs at the expense of scraps of shoots, reaching a length of about a meter and able to curl. Thin small leaves of bright green color and simply transparent, located on the shoots mutochato.
The plant contains female and male individuals. Able to let flowers only in a favorable environment. They have a long stem, and bloom above the water.
The flowers of the female individual have three inner and three outer petals, as well as three bright crimson stigmas. They have three sepals of greenish and reddish hues. Male flowers contain nine anthers.
The ovary contains approximately twenty ovules.
In Russia and in Europe there are practically no males. In the home aquariums, the elodea breeds only by grafting.
So that it grows quickly, the stalk must have a length of at least 20-25 cm. When there are fish in an aquarium, you do not need additional feeding for elodea – it consumes products released due to the vital activity of animals. In the presence of bright light instantly saturates the water with oxygen. It does not allow algae to grow in an aquarium, as it absorbs a large number of organic compounds present in the water and releases harmful substances into it.
They say that the juice from this plant is poisonous, and if the stem is broken, it will flow into the water and destroy the fry. But such situations have not happened yet.
Elodea absorbs parts of dregs that are in an aquarium, mainly when there are catfish. But do not use it as a filter – if the plant becomes dirty, then it develops worse, and it looks unattractive.
In order for this plant to grow all year in an aquarium, additional intensive highlighting is necessary, especially in winter. Otherwise, the plant will wither and eventually die.
Another elodea hard transfers, so-called, salting water used to heal the fish in the aquarium.
This type of plant, as the name implies, comes from the north of North America and therefore does not like too warm water. The limit for it is + 24 ° C, the temperature above depresses the Canadian guest, so in the so-called tropical aquariums it grows poorly.
But in a not very hard fresh water at moderate temperatures and bright light, especially in summer, this plant develops very rapidly. Its stems are densely covered with openwork leaves.
Planted at the back of the aquarium plant, growing, creates a wonderful emerald background for fish and plants with larger leaves.
This species comes from the tropics and subtropics of South America.
It has oblong narrow leaves up to five centimeters in length, which densely sit on the stems, forming very picturesque thickets in the depths of the aquarium. Her aerial roots are developing poorly, but this kind of elodea reproduces remarkably by cuttings.
This species is ideal for tropical aquariums and, moreover, it is very actively used in all other aquariums with an average temperature (up to + 26 ° C).
As mentioned earlier, this plant does not cause much trouble. It must be remembered that it is freshwater, and if you put an elodea in an aquarium with sea or salted water, it will die.
It is best to multiply anaccharis, if you maintain the water temperature in the range of 20-25 ° C. If it increases, the growth of all its types (except for gear) will slow down or stop completely.
The condition of this representative of the underwater world water hardness does not have a big impact. About it you need to think only in the case of transplanting plants from soft water to a more rigid.
As a result, the stems can be significantly reduced.
Of the external factors, elodeia is most affected by lighting. It should be equally good in all corners of the aquarium.
If in some part of it, for example, at the bottom, light does not reach the plant, then the leaves will begin to rot and fall.
In winter, the water plague almost ceases to grow and may die altogether due to a decrease in the intensity of natural lighting. To avoid this, it is important to create the necessary conditions using artificial light sources for the cold season.
Despite the simplicity, it is necessary to periodically filter the water. The fact is that the elodea itself acts as a filter. On its stems and leaves settles dregs from the water of the aquarium.
This is good for all inhabitants of the reservoir, except for the plant itself. Its appearance may deteriorate significantly.
Therefore, you need to install a filter pump or periodically flush the stalks of elodea independently under running water.
In addition to feed this type of aquatic plants is not necessary. It uses waste products of other living organisms for processing them into nutrients for themselves substances.
Elodea – a beautiful and unpretentious plant. It can develop in water of any hardness, but with a sharp change in this parameter it hurts and withers.
Some species grow better in soft water, and gradually dissolve in hard water.
The optimum water temperature in the aquarium is + 15 … + 22 ° C. If it rises above + 24 ° C, the growth slows down and the plant dies.
As the temperature drops, the stems descend to the ground and hibernate. In the spring of new points of growth appear shoots.
Elodea Canadian, in contrast to the heat-loving species, even without changing the parameters of the water freezes for several months.
It is very important for the plant bright lighting. If the sunlight in the room is not enough, you need to use fluorescent lamps.
They must completely see through the water column for at least 10 hours a day.
Turbid water is not a problem for the plant. It is even used as a water filter. All the suspension settles on the leaves, so the liquid quickly becomes transparent.
Themselves dirt particles serve as fertilizer for the algae, accelerating its growth. Also in the process of growth, elodeum releases bactericidal substances that prevent harmful microorganisms from developing in water.
It is important to remember that elodea is the inhabitant of freshwater bodies. Even a small amount of salt can destroy it.
Although this plant grows in almost any water body, many are interested in the question of how the process of its reproduction takes place. This process occurs as follows: the shoots are separated from the plant, reaching up to 1 meter in length, and transferred to an accessible free area of the aquatic environment, where they are already beginning to bloom.
Its reproduction in the aquarium is significantly different. In this case, this process occurs only by cutting, the minimum length of which must be at least 200 mm.
It is worth noting that this plant can be both female and male.
In order to determine the floor is enough to look at the flower itself. So the female is distinguished by 3 petals both inside and outside.
And this is not to mention the fringed raders with a bright crimson color. Also female individuals possess a sepal of red and green hue.
For male flowers, there are 9 anthers, and in the ovary there are up to 20 ovules. But, as a rule, in our climatic conditions, males do not survive. Therefore, this plant grows in its historic homeland.
A photo of a male plant can be seen below.
Elodea is not so popular anymore. More ornamental plants have supplanted it, but aquarists find it useful, maintenance-free, and recommended for beginners.
Some of the advice of experienced should listen:
- When planting, choose any soil, but not dirty and silted, additives from charcoal and lime are desirable;
- for the elodea to grow actively, she needs some shading in the summer period and additional overhead lighting in the winter;
- for greater “fluffiness” regularly cut off the tops and root them, and throw out the lower part of the plant.
