Vallisneria

maintenance and care, species, reproduction, photo-video review

Wallisneria is one of the most unpretentious aquarium plants. If you have never had an aquarium, you do not have experience in growing aquarium plants, start with Vallisneria. She does not need any special care. There are no stringent requirements for lighting, water or soil parameters. Vallisneria goes well with other aquarium plants, grows quickly and looks good on the side and background of the aquarium.

Family: Water colors (Hydrocharitaceae)
Rod:
Vallisneria

Types of Vallisneria

Spiral, American Vallisneria, Dwarf Vallisneria, Vallisneria twirled, Vallisneria floating, Vallisneria twist-leaf “mini-twister”, etc. (V. alternifolia, V. asiatica, V. biwaensis, V. caulescens, V. aethiopica, V. before. gracilis, V. gigantea, V. jaquinii, V. mmor, V. nana, V. linnei, V. natans, V. portugalensis, V. neotropicalis, V. spinulosa, V. pusilla, V. tortifolia, V. triptera , V. tortissima, etc.) Representatives of the genus are constantly being reviewed, systematized, and their names are changed, because of the great similarity of the plants, they are distinguished by the species of vallesneria by the length and width of the leaves, their color, shape, type of venation. Depending on the habitat conditions, the plant is able to change its “external data”.

The biological requirements of most representatives of Vallisneria are the same, so their detailing is not critical.

,
At the end of the article there is a video about vallisneria in natural waters.

Appearance: Vallisneria is a beautiful shrub with narrow ribbon-like leaves from 10 to 80 cm long. Vallisneria foliage is usually strong and elastic; different shades of green and red. Herbivorous inhabitants of the aquarium are not dangerous, except for digging species that can pull out a poorly rooted plant. Some forms of Vallisneria have very sharp leaves due to small cloves. Therefore, you need to carefully handle it, so as not to cut your fingers. In nature, sometimes in home pond conditions, subject to the presence of abundant sunlight, valisneria blooms with beautiful small bells that adorn the water surface.

Root system: developed in moderation. Milky yellow roots up to 10 cm in length. The roots are elastic, not prone to morbidity, easily, compactly assembled and planted in the hole during planting. Deepening - with an open root neck.

Priming: composition and structure are not fundamental. Ideal - gravel fraction from 4 to 6 mm. The thickness of the soil is 4 cm. The substrate should be the most permeable, then the plant will take root soon and develop well.

Lighting for vallisneria

Preferably bright illumination, but vallisneria develops well with more muted light. The light spectrum does not matter.

Water parameters for vallisneria

Comfortable temperature: from 18 to 32 ° C. If the water is cooled for a long time to 15 ° C and tends to decrease, the plant may die.

"Acidity" Ph: weak or neutral.

Stiffness dH: average.

Salinity of water: from 0 to 20 ppm.

If you have a frame aquarium or bad tap water, watch the rust concentration in it, the plant does not like it. An excess of copper in water also affects the development of Vallisneria. This metal can get into the aquarium together with preparations against snails and algae, as well as with medicines for the treatment of fish.

Placement and landing of vallisneria in an aquarium

It is better to plant vallisneria along the back and side walls in a group of several plants and quite tightly. It forms a beautiful green wall and is the perfect backdrop for all types of ornamental fish. To make it easier for you to take care of the aquarium garden in the future, you should purchase Vallisneria from a group of mother and daughter plants.

It is convenient to plant the valisneria next to the filter, in the place of water discharge. Due to the flow of water, the plant will be evenly distributed over the surface. Vallisneria can also be used as a restriction on the spread of free-floating plants by placing its leaves in the form of small islets. To fix the position of the vallisneria afloat, you can use snags or strong leaves of other plants (for example, Echinodorus).

Care and pruning Vallisneria

When the leaves of valisneria reach the surface of the water, they frame it beautifully from above. If there are not many plants, they do not impede the free access of the necessary amount of light to the aquarium. Otherwise, you should get rid of them. Vallisneria better thin out. After pruning the foliage looks unnatural, it turns yellow and may rot.

Vallisneria reproduction - vegetative

The “babies” of valisneria are formed at the base of the mother plant. The barb is fixed at a distance of 5 to 10 cm from the mother bush, a daughter plant is formed, and then it develops further. There may be about 50 of them in a year. Rooted children with 3-4 leaves 7 cm long can be separated from the mother plant. Seed propagation
impractical

Wallisneria does not require undue attention to itself, does not need special care, but it is impossible to completely ignore the needs of the plant for development. For some time, valisneria can grow in poor soil, with poor lighting and muddy water, but for the time being. In the end, the plant will begin to languish: almost cease to grow, the leaves will become shorter and fade. Therefore, at least sometimes the grass should be fed with complex fertilizers in the form of tablets or paste. Water should also be changed regularly. But the peat and clay in the soil is not necessary. Vallisneria also do not need carbon dioxide.

Synonyms: Sometimes this plant is called and written as walisneria, with one beech "l". However, it is correct, yet to write with two vallisneria - vallisneria.

American valisneria

Vallisneria americana var. americana

The plant is unpretentious, does not require much attention. American valisneria has many forms that vary in width and length of leaves.

Growing area: Eastern North America.
Forms and appearance: leaves are collected, in the form of rosettes, ribbon-shaped, brittle and soft, sometimes at the edges with the teeth. Representatives of the American Vallisneria subspecies may differ in the structure of the sheet plate and its color (from various shades of green to many shades of red).

Leafy handicaps: leaf width is about 10 mm, with several veins and distinct horizontal strokes.

Broadleaf forms: sheet width up to 25 mm, the vein can be from 5 to 9 pieces. Priming: loose, rich in nutrients, up to 7 cm thick, in tandem with liquid and horse fertilizers, which include iron, is the best option for the full development of the plant.

Lighting: bright, 12-hour light day.

Water parameters:

Comfortable temperature: 20-28 ° C.

"Acidity" Ph: 6,5-8.

Stiffness dH: 5-15°.

Accommodation in the aquarium: When planting a vallisneria in your aquarium, it should be remembered that the plant grows up to 1 m in height, therefore it can significantly impair the coverage of the underwater world of your pond. If you nevertheless decided to acquire such water weed, then pick up the inhabitants of the aquarium, which is acceptable muffled light.

It is worth noting that Vallisneria americana is most attractive in very large aquariums. A good planting option is about 4 plants per 20 cm2.

American Wallisneria is a background plant, so they are planted along the back and side walls of the aquarium.

The complexity of care: low.

Trimming: you can cut the leaves, but not necessary. After pruning, the plant's appearance deteriorates and its growth weakens.

Reproduction: vegetative, uniform.

Spiral valisneria

Vallisneria americana var. biwaensis

Growing area: southern usa.
Appearance:
spiral leaves, twisted into a corkscrew, up to 5 cm in width and about 50 cm in length.
Root system:
gentle, white color.
Priming:
should consist of fine fractions (up to 2-3 mm). In the place of landing the layer is not less than 4 cm thick.

neutral or slightly acid.
Stiffness dH:
not higher than 8 °.
Regular water changes.
Accommodation in the aquarium:
Looks good in the center or in the foreground of a large aquarium.
Reproduction: vegetative, layering.

Giant valisneria

Unpretentious aquarium plant. Due to the large size it needs an aquarium of solid parameters. For this reason, giant gallium is not popular among aquarists. It grows with proper lighting evenly throughout the year.

Growing area: Southeast Asia.
Appearance:
large bushes straight stiff leaves up to 1 m in length, different shades of green.
Root system:
Priming:
coarse (pebbles or sand with a grain of 3-4 mm), nutritious. The plant feels good from old aquariums, where there is a large amount of organic matter. Soil thickness - not less than 8 cm.
Lighting:
bright, 12 hour light day. If the aquarium is low, lateral lighting is desirable, as an addition to the upper one.

Water parameters:

Comfortable temperature: 22-26 ° С, it should not be allowed to fall below 20 ° С. "Acidity" Ph: mild, weakly acidic medium.
Stiffness dH:
less than 8 °.
Regular water changes are not critical.
Accommodation in the aquarium:
can only be grown in a large aquarium.

Reproduction: vegetative, layering.

Wallisneria nana (dwarf)

Vallisneria nana

Growing area: Northern Australia.

This wallisneria has a short rhizome, forms lateral shoots. In an aquarium it reaches sizes up to 30-60 cm, which depends on the power of lighting and the nutritional value of the medium. The plant has dark green narrow leaves. The leaves in the socket, much narrower than those of other members of the genus Vallisneria, and not very long. It has small teeth on the edge on the top of the sheet. Wallisneria nana has two forms: either the leaves are hard and up to 15 cm long, or thin, ribbon-like, drooping, surprisingly narrow, smooth, up to 60 cm long.

It is unassuming, like all Wallisnerias, a fast-growing aquarium plant. It is recommended for decorating the middle and background in small aquariums.

It has a longer growth phase and is more light-loving than other Wallisnerias, otherwise unpretentious. Wallisneria nana well develops in alkaline water of medium hardness at a temperature of 25-29 ° С, tolerates deviations from the specified parameters. It forms many lateral processes and develops well under good conditions. The dwarf Wallisneria has a longer period of adaptation than the other Wallisnerias. If the plant is well taken, it will continuously give daughters.

Giant

Vallisneria is a perennial aquatic plant of the Vodokrasov family. Gradually, the plant spread from tropical reservoirs to a zone with a temperate climate. Wallisneria is very popular in aquariums due to its resilience, simplicity and external decorative appeal. By planting an aquarium with a long-vallisneria, sagittarium, myriophyllum, you can achieve an interesting solution in the design of a long tank, which will be especially comfortable for zebrafish. There are many varieties of Vallisneria, the most popular are Vallisneria spiral, giant Vallisneria, tiger and nano.

Description

Vallisneria is a pretty shrub with ribbon-like narrow leaves, depending on the type reaching from 10 cm to 2 meters in length. This plant is distinguished by the strength and elasticity of its leaves, the color of which can be green and reddish. The root system is quite developed, the flexible rhizomes are up to 10 cm in length. In good conditions, the vallyseria often blooms with small flowers-bells, but does not form seeds, because its flowers are same-sex.

Kinds

Spiral

The plant owes its name to the Italian botanist Antonio Vallisneri. And his type of spiral vallyseeria is named so not for the shape of its leaves, but for its peculiarity that the naturalist Linnaeus has noticed. Helix vallisneria has a spiral that appears due to the flower-bearing stem of a female flower curling after pollination. Spiral Wallisneria is considered the most common type of plant; it has corkscrew twisted or linear leaves of bright green color up to 20 cm long. In the most favorable conditions, spiral Wallisneria grows to 80 cm.

Spiral Wallisneria is a very useful plant, as it effectively releases a large amount of oxygen, which is so necessary for many inhabitants of the aquarium.

Helix Vallisneria is able to grow in an aquarium all year round and multiplies rapidly. Spiral Wallisneria looks perfect at the side and rear aquarium walls, planted in small groups, which turns its walls into a favorable green background for all its inhabitants.

Tiger

Tiger Wallisneria is a subspecies of the spiral species and is distinguished by the presence of dark strokes on the leaves that resemble tiger stripes. Its leaves will brightly decorate the aquarium, if the plant is planted on the sides, as an excellent background for ornamental fish. The tiger wallisneria can grow up to 1 meter and form picturesque thickets of oblong green leaves.

Giant

Vallisneria giant endowed with attractive leaves of dark green color. In size, this plant can be up to almost 2 meters in length and 4 cm in width and is well suited for a front corner in a large aquarium. Its bushes can be a great haven for small species of fish. Vallisneria giant rarely grown in domestic aquariums because of its impressive size.

Natans

Vallisneria natans is a type of American plant species. This species has long thin and narrow leaves, growing to 100 cm in length, usually planted along the side and rear walls of the aquarium. The plant is able to grow quickly in diffused light and does not obscure other plants growing in the lower part of the tank. Wallisneria natance also copes well with the participation in the exchange process and the saturation of water with oxygen.

Nana

Wallisneria nana or dwarf has a miniature appearance. Its thin dark green leaves are drawn to the surface of the water, even without giving a shadow. Under natural conditions, the plant reaches up to 70 cm, and in aquariums it does not exceed 30-50 cm. Considering the size of the aquarium, the valisneria nana is planted by small bushes in the middle plan of the tank.

Spinning leaf

Vallisneria twisted leaf has beautiful and strongly serrated or spiral leaves, reaching up to 40 cm in length and 8 mm in width. This species is best planted in the background of the aquarium or on the sides.

Content

Spiral

The maintenance of vallisneria is not a problem and is suitable for all lovers of aquariums. A moderately warm and tropical aquarium with a temperature regime of water of 20-28 ° C is suitable for the plant of vallisneria, and at a lower temperature the growth will obviously slow down. The hardness of the water must be up to 8 °, otherwise the leaves will be ground and the growth of the plant will deteriorate. Acidity may be in the range of 5-7 with a neutral or slightly acidic aqueous reaction. Water replacement is recommended to be done regularly, although Vallisneria can tolerate old, long-replaceable water. But in the aquarium must have a quality filter.

The soil is chosen well silted and nutritious, when planting in a sufficiently silted soil does not need additional feeding. Due to the gentle root structure of the plant, medium or large river sand 3-4 cm thick is used as a substrate. Spiral Wallisneria is a rosette plant rooting in the ground. Its whitish roots spiral valisneria firmly strengthens in the ground, so that it will not break away from the bottom and float. For the type of nano fine gravel or sand with a layer of 4 cm.

The plant is undemanding to the brightness of the light, just with a lack of light, it turns yellow and will stretch. Useful natural light, you can use artificial light sources, the power of which must be selected individually, given the presence of other plants in the aquarium. Duration of daylight hours within 8-16 hours.

Breeding

In favorable conditions, the content of vallisneria naturally easily propagates by vegetative means and produces many daughter shoots. During the year, the mother plant gives several tens and hundreds of young shoots, which can be separated after the formation of 2-3 leaves or the growth of roots.New bushes are formed on the whiskers, they are strengthened at a distance of 5-10 cm from the parent bush, and in a fairly short time a magnificent cascade of numerous bushes is formed. Spiral vallisneria rarely blooms in an aquarium, as its reproduction by seed in captivity is not enough for anyone.

Care

Nana

Wallisneria is prone to rapid reproduction, so it is recommended to thrive it in a timely manner, otherwise it will grow into too thick undergrowth. Usually, the edges of the old leaves of a plant are rather hard; this is due to the fact that the valisneria accumulates calcium salts on its leaves.

Regarding leaf clipping at Vallisneria, opinion was divided. According to one version, the old leaves with yellowed tips need to be cut, which will be useful both for the plant and for the general appearance in the aquarium. But according to a more modern method, it is recommended to thin out the plantings, reducing the number of bushes, since the leaves of the cut plant will be doomed to death. At first the leaf turns yellow, then rots and eventually dies.

  • One of the important conditions for the maintenance of a plant is that rust, copper and iron salts, which stand out from the ordinary iron frame of the tank, do not fall into the aquarium.
  • If the vallisneria does not grow, then apply periodic CO2 fertilizing.
  • Care should be taken when caring for some varieties with pointed ends that may injure human skin.

All types of plant Vallisneria extraordinarily beautiful and have very useful properties. This plant is perfect for beginner aquarists because of its undemanding and easy care, and the species of spiral wallisneria can easily be found in pet stores, as it is widespread in the local region. The water in the aquarium, which will have a lot of vallisnerium, will always be clear and clean thanks to these plants, which absorb harmful components like a filter and release oxygen.

Helix Vallisneria - how to plant and contain

Vallisneria (lat. Vallisneria) is an aquatic plant, belongs to the Vodokrasovye family. Today, the following types of vallisnerium are known, the contents of which are possible in a home aquarium: spiral vallisneria, American, nana, gigantic. All species have common morphological characteristics.

The plant is characterized by leaves collected in a rosette, which is strengthened in the ground with the help of long shoots. Leaf color can be bright green or with a red tint. Stems developed and branched, leaves whorled, there are axillary scales. There are species with large and spirally twisted leaf plates (helixneria spiral). The length of the leaves - 100-200 cm, they reach the surface of the water, creep along the water surface.

Content policy

Vallisneria is a famous aquarium plant that adapts well in captivity. Its leaves can grow up to 70 cm in higher, and look spectacular in spacious tanks. It is better to plant the plant in small groups at the back or middle plan of the aquascap, or in the corners. He likes nutritious soil, fine gravel or sand will be suitable as a soil.

The roots of Vallisneria are moderately developed, white in color, flexible, their length reaches 7-10 cm. Plant can be planted in a prepared planting hole. It is possible to dig deep by opening the root neck. The thickness of the soil is recommended 3-4 cm.

Admire the aquarium with Vallisneria americana.

When Wallisneria reaches the surface of the water, its leaves line out along it, and cover the water surface, shading the aquarium from above. If the leaves grow moderately, they will not have to be cut, otherwise, the falling shadow will limit the access of light to other plants. When an overly large bush, it is better to remove them completely, without pruning. Clipped plants will only deteriorate and rot.

Periodically, the plant can be fed fertilizer. All types of vallisneria can receive complex types of fertilizers. Choose fertilizers in the form of tablets or special pastes. Vallisneria spiral loves clean water, so once a week, update 30% of the water to a new one. Additionally, making clay or peat is optional.

Vallisneria spiral and nana have excellent decorative properties. Their wide leaves will form a thick aquascape in which the fish will hide. Durable leaves of the plant are unlikely to become the food of fish in the aquarium. Large cichlids and catfish Loricaria do not bother their Vallisneria. Bottom, digging fish can tear the roots out of the ground, therefore in the aquarium with such fish the maintenance of the plant is hardly possible.

Breeding methods

Vallisneria is a dioecious type of plant, there are male and female bushes on which flowers periodically bloom. They are small or unremarkable, occasionally - large. Several inflorescences may form from one leaflet's sinus. The perianth has two circles - external and internal. Pollination occurs in a hydrophilic way.

In an aquarium, species of vallisnerium bloom unusually. Their solitary pistil flowers appear above the surface of the water. After the process of pollination, the peduncle spins in a spiral, and the pollinated flower dries under the water, where the fruit ripens. After ripening, staminate flowers are separated from the plant, rise to the surface water layer, and female flowers are pollinated.


In addition to the seed method of reproduction, all types of vallisnerium can multiply by vegetative means. Shoots that line the ground, or embedded in the soil, form buds. Over time, they will turn into small daughter shoots, which, after rooting in the soil, will eject cuttings to form new plants. During vegetative propagation, valisnerium bushes in a short time form lush thickets.

Spiral Wallisneria

Spiral Vallisneria is a beautiful and popular aquarium plant. It is characterized by long ribbon-like leaves of bright green color. They are twisted in the form of a "corkscrew", and form a dense bush that can reach the surface of the water even in a shallow aquarium. Leaves can grow up to 80 centimeters long, but more often their length is 45-50 cm. It looks great at the back and side walls of the reservoir. Due to the simplicity of the content and high reproduction rate, it can be bred even for beginners. Grows in captivity year-round.

Watch a video about spiral vallisneria.

Vallisneria spiral is not sensitive to the amount of light in the tank. For her suitable moderate lighting, which can be issued using fluorescent lamps. The recommended duration of daylight hours is from 10 to 12 hours. It grows well and develops in water soft or medium hard. Acidity pH 6.0-7.5 pH. Allowable water temperature for content: 22-27 ° C. Replacement of aquarium water - once a week, filtration is required, especially in the presence of fish in the pond.

In the wild, it propagates vegetatively, or with the help of seeds. Under conditions of captivity and limited space, spiral valysennium is difficult to propagate with the help of seeds. All the year round she lets out escapes on which child sprouts are formed. During the year, the mother bush can bring more than 200 shoots. He lets out a mustache, and at a certain distance the daughter bush will grow. It may happen that it fills the entire space of the aquascap. Periodically, it is necessary to weed, removing unnecessary bushes.

Aquarium plant "hellesnierium spiral": description, reproduction, maintenance and care

One of the most common plants of the Vodokrasov family is considered to be valisneria. The maintenance and care in the aquarium for her is of interest to most people who are not indifferent to the creation of natural places.

Wallisneria: where did it come from and where is it growing?

Despite the fact that its natural habitat was originally a subtropical zone and hot tropics, today the plant is often found even in some waters of the southern regions of Russia. In addition, adapted to the stagnant water of lakes and ponds, in swift river flows, it also survives well. The originality of the appearance of Vallisneria is given by bright green leaves.

Spiral Vallisneria is extremely popular among landscape designers today. It is actively used to decorate artificial ponds or high huge aquariums. Thanks to the unpretentiousness of the plant, even beginner aquarium lovers can grow up valisneria.

Spiral leaf underwater plant description

Most plants of this type are extremely fastidious: for them it is necessary to select a special soil, to provide adequate lighting, to maintain only a certain temperature of the water. Vallisneria spiral, on the contrary, is very unpretentious. Its bushes are excellently developed on the sandy bottom of a dense fraction or among the stones, pressing its roots under water. Of course, the plant needs light in the first place for timely and long-term flowering. Therefore, in the natural environment, it blooms only in summer, and at home it is possible to achieve long-awaited flowers resembling white bells, even in spring.

A feature of the leaves of valisneria is their rigidity. Having similarity with narrow green satin ribbons, reaching a length of up to 70 cm, they are so sharp that with carelessness they can hurt the hand.

Significance of Vallisneria in an aquarium or pond

The supply of oxygen is the merit of the plant in the exchange processes of the aquarium. Taking useful organic matter from the soil, it creates all the conditions for the full existence of living organisms in the water of vallisneria. Maintenance and care (plant species are numerous, but several of them are primarily in demand), performed in accordance with the requirements of cultivation, will allow the bushes to multiply at an unprecedented pace. In this connection, the valisneria needs regular thinning of densely growing thickets.

It is extremely important to remember that sometimes in shallow ponds or aquariums of insufficient height, the leaves of the plant create an almost impassable green veil, which prevents natural light passage. The solution to this problem is one thing - reducing the bushes of growing vallisneria.

What can harm underwater bushes?

It is possible to thin out planting, but it is impossible to shorten the leaves under any circumstances. A resilient Vallisneria spiral will simply be doomed to ruin. After cutting the leaves will begin to turn yellow, rot and eventually disappear.

The presence of certain minerals in water can adversely affect its growth. For example, the salt solution used to treat aquarium fish negatively affects the condition of the bushes: when it is used, the leaves grow dull and become sluggish. Thus, not only this aquarium plant reacts to table salt.

Spiral Vallisneria does not tolerate rust. Such a problem is not uncommon for many owners of decorative aquariums in Russian cities. Using tap water flowing through iron rusting pipes as a filler, the owners risk destroying everything in the aquarium.

Food supplements for fish

The presence of copper salts in water, which are sometimes used in the manufacture of preparations against algae and slugs, also does not benefit the vallisneria. And although manufacturers often refute the likelihood of a negative effect of drugs on aquarium vegetation, the reviews suggest otherwise. In particular, after adding Bicillin-5, a medicine for fish, spiral vallisneria, the giant die.

Giant Vallisneria

This type of underwater plant is no less common among aquarists. The name predetermines the possibility of institution of such Vallisneria only in spacious high vessels of a home pond. Under normal conditions, the giant leaves of valisneria can reach two meters in length. This type, as well as the spiral Vallisneria, is unpretentious in care, it withstands for a long time both the lack of necessary illumination and temperature differences.

Plant propagation

In order to propagate in a vegetative way a popular representative of the aquarium flora at home, it should create an optimal environment close to the natural one. As a rule, a mustache grows in Vallisneria, which subsequently form daughter bushes. Young plants can be separated from the mother plant after the formation of several leaflets and root lobes from the daughter plants. Having cut a mustache, it is possible to receive a separate bush ready to independent existence.

Grow vallisneria seed method at home is quite difficult. In addition, experts find it impractical because the plant is dioecious. This means that each individual shrub forms male and female flowers.

Human use of valisneria

For domestic purposes, vallisneria is not used. However, biologists have repeatedly tried to identify the additional benefits of an underwater plant that could be used on the farm. They managed to experience spiral bushes in the process of cleaning runoff waters in urbanized centers. The moderately warm temperature of the drains would allow the Wallisneria to grow and spread year-round.

In Russia, such studies were carried out in one of the scientific institutions of the Perm Territory. Then, the results of the experiments demonstrated that, due to the presence of this representative of water-to-beauty plants, the content of harmful salts of nitrogen and phosphorus was several times less. In this case, experiments were carried out only in settling tanks with slow water flows.

Features of care and maintenance of spiral wallisneria

A frequent guest in aquariums is a spiral valisneria brought from far abroad. The main supplier of underwater species of plants are the southern states of North America. Its characteristic difference can be called the wider leaves, twisted as if in a tailspin.

Approximately + 20 ... +25 degrees is considered the ideal temperature for this type of plant. In a colder reservoir, its condition does not deteriorate, but there is a clear slowdown in growth. Periodic or partial change of water in the aquarium also has a positive effect on the plant.

To create the most favorable conditions for living in the artificial environment of valisneria, the acidity and hardness of the water should ideally be neutral.

The lack of daylight contributes to excessive stretching of the leaves, after which they begin to brighten and turn yellow. Indoors, an aquarium with bushes of such a plant should be lit for at least 12 hours.

If spiral vallisneria does not grow, the problem may be hidden in the ground or in the state of the root system. The white roots are quite gentle rooting and consist of small veins, which means that it is convenient for them to grow in well-washed river sand. When creating the soil in an aquarium with your own hands, it is necessary to remember its preferred thickness - not less than 5 cm. In addition, it is important to feed the underwater soil at least for the first time after planting, although if there is no need for additional fertilizers in the aquarium, there is no need for additional fertilizers.

In home care special difficulties does not cause spiral vallyseneria. Diseases of plants can be caused by a single reason - the low quality of tap water. When filling the aquarium, it is necessary to take into account this fact, as the owners often miss such an important detail and begin to look for problems of plant growth in lighting, water temperature and fish feed.

If you want to grow a real healthy vallisneria, which will become an element of decor not only for an aquarium vessel, but for the whole house, you do not have to buy new soil. When replacing an aquarium, the old soil from the previous vessel will come in handy: at the bottom there is usually a lot of organic matter useful for plants.

Vallisneria spiral-content, species, description, breeding.

Habitat

In natureSpiral valisneria grows in the tropics and subtropics. In Russia Vallisneria occurs in Central Asian waters, as well as in the water expanses of the basins of the Volga, Don, Dnieper and Kuban.

Appearance

Spiral valisneriais quite popular type of aquarium plants. Spiral valisneria has a ribbon-like leaves of rich green color, which grow, reach the surface of the water surface. Leaves of Vallisneria are twisted in a spiral. If the plant survives well, its leaves can reach a length of 70-80 centimeters. Although statistics indicate a plant length of 50 centimeters. AT aquarium Wallisneria takes place in the background or near the side walls.

Conditions of detention

Simplicity Vallisneria spiral, the simplicity of its reproduction and the ability to grow throughout the year, make it one of the favorite plants, even among novice aquarists. The optimum water temperature for keeping vallisneria spiral is 20-28 ° C in tropical or moderately warm aquariums. If the water is cooler than the indicated range, plant growth slows down. In addition, the growth of the plant is affected by water hardness, the optimal indicator of which is considered to be 8 °, while the pH should not exceed 5-7. Spiral valisneria requires regular water changes, moderate or bright lighting. При недостаточном свете валлиснерия вытягивается, листья приобретают желтоватый окрас. В качестве источника освещения можно использовать как естественный свет, так и искуственный, в качестве подобного источника света можно включать лампы дневного света или лампы накаливания. Продолжительность светового дня от 8 до 16 часов. Растение рекомендуется высаживать в питательный, хорошо заиленный грунт. Дополнительной подкормки Spiral valisneria does not require. Since the root system of the plant is very delicate, therefore it is better to use river sand as the soil.

Spiral Vallisneria is one of the most common aquatic plants that take root in conditions of ordinary aquariums. The main thing in caring for an aquarium with it is to maintain the temperature of the water in an artificial pond not below 20ºС. Cool water slows down plant growth significantly. Too hard water also adversely affects the size of the leaves and their overall development.

In order for the plant to develop and delight others with its beauty, it is necessary to provide it with the following conditions:

• Requirements for the acidity of water 5 - 7pH;

• stiffness dGH - up to 8 ° Ж;

• The required water temperature is 20 - 28 ° С;

• Requires powerful lighting;

• Fertilizing plants - is not required;

• Submission of CO2 to the aquarium is not required;

• Soil - coarse river sand.

It is advisable to change the water in aquariums regularly, in the proportion of 1/5 of the total volume. However, the breaks in the change of water will not bring any harm to the plant.

Breeding vallisneria spiral

When creating good conditions for a plant in an aquarium, you can not worry about its reproduction. Numerous shoots that are formed in this case, can bring up to several dozen daughter plants.

The separation of new roots, as a rule, is carried out after the appearance of the roots and a few leaves on the young shoot. Spiral vallisneria blooms quite often, but has no seeds because of same-sexness.

Appearance: Vallisneria is a beautiful shrub with narrow ribbon-like leaves from 10 to 80 cm long. Vallisneria foliage is usually strong and elastic; different shades of green and red. Herbivorous inhabitants of the aquarium are not dangerous, except for digging species that can pull out a poorly rooted plant. Some forms of Vallisneria have very sharp leaves due to small cloves. Therefore, you need to carefully handle it, so as not to cut your fingers. In nature, sometimes in home pond conditions, subject to the presence of abundant sunlight, valisneria blooms with beautiful small bells that adorn the water surface.

Root system: developed in moderation. Milky yellow roots up to 10 cm in length. The roots are elastic, not prone to morbidity, easily, compactly assembled and planted in the hole during planting. Deepening - with an open root neck.

Priming: composition and structure are not fundamental. Ideal - gravel fraction from 4 to 6 mm. The thickness of the soil is 4 cm. The substrate should be the most permeable, then the plant will take root soon and develop well.

Lighting for vallisneria

Preferably bright illumination, but vallisneria develops well with more muted light. The light spectrum does not matter.

Placement and landing of vallisneria in an aquarium

It is better to plant vallisneria along the back and side walls in a group of several plants and quite tightly. It forms a beautiful green wall and is the perfect backdrop for all types of ornamental fish. To make it easier for you to take care of the aquarium garden in the future, you should purchase Vallisneria from a group of mother and daughter plants.

It is convenient to plant the valisneria next to the filter, in the place of water discharge. Due to the flow of water, the plant will be evenly distributed over the surface. Vallisneria can also be used as a restriction on the spread of free-floating plants by placing its leaves in the form of small islets. To fix the position of the vallisneria afloat, you can use snags or strong leaves of other plants (for example, Echinodorus).

American valisneria

Vallisneria americana var. americana

The plant is unpretentious, does not require much attention. American valisneria has many forms that vary in width and length of leaves.

Growing area: Eastern North America.
Forms and appearance: leaves are collected, in the form of rosettes, ribbon-shaped, brittle and soft, sometimes at the edges with the teeth. Representatives of the American Vallisneria subspecies may differ in the structure of the sheet plate and its color (from various shades of green to many shades of red).

Leafy handicaps: leaf width is about 10 mm, with several veins and distinct horizontal strokes.

Broadleaf forms: sheet width up to 25 mm, the vein can be from 5 to 9 pieces. Priming: loose, rich in nutrients, up to 7 cm thick, in tandem with liquid and horse fertilizers, which include iron, is the best option for the full development of the plant.

Lighting: bright, 12-hour light day.

Water parameters:

Comfortable temperature: 20-28 ° C.

"Acidity" Ph: 6,5-8.

Stiffness dH: 5-15°.

Accommodation in the aquarium: When planting a vallisneria in your aquarium, it should be remembered that the plant grows up to 1 m in height, therefore it can significantly impair the coverage of the underwater world of your pond. If you nevertheless decided to acquire such water weed, then pick up the inhabitants of the aquarium, which is acceptable muffled light.

It is worth noting that Vallisneria americana is most attractive in very large aquariums. A good planting option is about 4 plants per 20 cm2.

American Wallisneria is a background plant, so they are planted along the back and side walls of the aquarium.

The complexity of care: low.

Trimming: you can cut the leaves, but not necessary. After pruning, the plant's appearance deteriorates and its growth weakens.

Reproduction: vegetative, uniform.

Accommodation in the aquarium:
can only be grown in a large aquarium.

Reproduction: vegetative, layering.

Wallisneria nana (dwarf)

Vallisneria nana

Growing area: Northern Australia.

This wallisneria has a short rhizome, forms lateral shoots. In an aquarium it reaches sizes up to 30-60 cm, which depends on the power of lighting and the nutritional value of the medium. The plant has dark green narrow leaves. The leaves in the socket, much narrower than those of other members of the genus Vallisneria, and not very long. It has small teeth on the edge on the top of the sheet. Wallisneria nana has two forms: either the leaves are hard and up to 15 cm long, or thin, ribbon-like, drooping, surprisingly narrow, smooth, up to 60 cm long.

It is unassuming, like all Wallisnerias, a fast-growing aquarium plant. It is recommended for decorating the middle and background in small aquariums.

It has a longer growth phase and is more light-loving than other Wallisnerias, otherwise unpretentious. Wallisneria nana well develops in alkaline water of medium hardness at a temperature of 25-29 ° С, tolerates deviations from the specified parameters. It forms many lateral processes and develops well under good conditions. The dwarf Wallisneria has a longer period of adaptation than the other Wallisnerias. If the plant is well taken, it will continuously give daughters.

Giant Vallisneria in the home aquarium

Vallisneria gigantic (lat. Vallisnéria gigantea) is an aquatic plant, belongs to the family Vodokrasovye, division of Angiosperms. The natural environment of distribution is the islands in South-East Asia. Today, the maintenance of the plant is possible in home aquariums.

Description

Vallisneria giant has a large size. The leaves are linear, painted in dark green color, their length is 10-20 cm. Rhizome creeping. Dominous plant species. On one bush only homosexual flowers are formed. The main advantage of Vallisneria is unpretentious content. It grows well at water temperatures above 20 ° C. Lowering the temperature stimulates her to gain strength and do everything to survive in such conditions. However, it does not lose its decorative properties, however, a long period of such conditions is fraught with the death of the plant.

Look at the Dutch aquarium with a giant valisneria.

The long leaves look magnificent and impressive, decorating the underwater aquascape. The aquarium should be spacious and rectangular in shape - in such capacity it is easier to care for the plant. The height of the tank is recommended 60 cm. At the bottom you need to lay a layer of soil. If the aquarium has a volume of more than 600 liters, then the leaves of the giant Wallisneria will grow to the surface of the water, and will occupy a large area. Not everyone can take care of such an aquarium. Have to hire cleaners, or swim there yourself. In any case, the plant will have to be cut so that its shadow does not affect other types of plants. It grows all year round.


Content policy

The content of giant vallisneria is possible in water with a temperature of 22 to 26 ° C. The lower temperature threshold is 20 degrees. It can carry a wide range of parameters of the aquatic environment. It grows well in hard and soft water, with an alkaline or acidic pH. Ideal indicators - soft water with a weak acid reaction, the level of total hardness should not exceed 8 o. Water should be clean, once a week you can make a replacement of 20-30% of water, depending on the volume of the tank.

Vallisnéria gigantea prefers rich lighting. Because of this, it may happen that it grows thick, and if you do not prune the bush, it will obscure the neighboring plants. You can think of installing side lighting so that the low bushes of other plants receive enough light. The number of hours of daylight hours is 10-12 hours. Light can be supplied using 0.5 W fluorescent lamps.

Watch the video about the vallysnia.

As the soil suitable nutrient soil in the form of sand or pebbles with clay. Under the roots, you can put clay balls. The first time after the launch of a new aquarium, natural silt will be suitable for feeding. Consider the characteristics of other plants, so that the soil is suitable for all species. The maximum soil layer is from 8 to 10 cm. If you decide to add mineral dressing to an aquarium, remember that sodium ions in excess have a bad effect on the plant. Also, soda and salt should not be added to the water - giant vallisneria does not tolerate them. For this reason, it is not recommended to keep it with fish that love salted water (some fish of the Family Petsilievye).

Giant vallisneria propagates vegetatively. From the adult mother plant are soil roots, directed in different directions. Child shoots can be transplanted when several leaves and root lobes are formed. In ordinary reservoirs, vallisneria cannot multiply with the help of seeds. But in aquariums, where there is a dense population of plantations, there is the likelihood of seed multiplication and flowering. As a dioecious type of plant, Vallisnéria gigantea forms same-sex flowers, so in order to get viable seeds, you should plant more heterosexual seedlings in the tank, and wait for them to bloom simultaneously.

It is recommended to plant vallisneria in tropical reservoirs, or in reservoirs with a temperate climate (in our latitudes it gets along well). This is a viable plant that will adorn an aquascape for many years. If you plant a giant vallisneria, myriophyllum, sagittarium in a reservoir, then for small fish they form excellent shelters. There are other types of vallisneries that look good next to Vallisnéria gigantea.

Plant description

Vallisneria gigantic is a very large aquatic plant with narrow green leaves that can grow up to a meter in length. They are very tough, so they are not eaten by the inhabitants of ponds and aquariums. These ornamental shrubs have a creeping rhizome, color - from dark green to bright lettuce, depending on the light and other growing conditions.

The leaves of Vallisneria are melkopilchatye on the sides, and above - smooth and rounded. It multiplies mainly vegetative way, since the adult plant gives many mustache layouts. They can be separated from the mother plant and transplanted when they have 4-5 of their leaves.

In nature, this dioecious plant blooms with small white gramophone floats floating along the surface of the water along with the leaves, and multiplies with seeds that are tied to female specimens. To get seeds at artificial cultivation, it is necessary that in the same reservoir or aquarium contain different-sex plants, and a lot of flowers should be formed on them, and at the same time, which is difficult and impractical.

This tropical perennial loves soft and warm water, well silted soil. Growing strongly, it forms a dense layer of green mass on the surface of the water, preventing light and air from penetrating into a pond or aquarium.

CONTENT AND CARE

Vallisneria does not like the presence of certain mineral substances in the water. The treatment of fish with a solution of salt in the general aquarium, where such landings are present, should not be carried out, since this disturbs its growth.

Nevertheless, I used salt in aquariums with this member of the Vodokrasov family. With a small concentration of table salt, characteristic of viviparous fish, there is no significant deterioration in the growth of such green spaces.

It also does not like Vallisneria rust in water. This problem occurs in cities where tap water is used to fill aquariums. Very often in Russia it comes with rust, due to the use of iron pipes. Also, rust can get into the water when using frame aquariums. Does not like this plant and excess copper in water.

Sometimes the salts of this metal are included in the preparations against algae and snails. A similar situation may arise in the treatment of fish. There is unverified information that Vallisneria dies when using Bicillin-5 for the treatment of fish.

Vegetatively propagated in the domestic waters of this popular representative of the aquarium flora. In good conditions, she independently produces a mustache, on which daughter bushes are formed. Young plants can be separated from the uterine bush, cutting a mustache, after the formation of 3-4 leaves and lobes of roots. Propagation by seeds at home is difficult and not advisable. This is also due to the fact that Vallisneria is dioecious and on each of its specimen flowers are formed either male or female.

This member of the Vodokrasov family has no economic significance. There have been attempts to use it, on a par with Elodiea, for cleaning drains in large cities. Sewage is warm enough that Vallisneria could grow and multiply in them all year round.

Even at Perm University studies were conducted. When a treatment plant is used in a tertiary clarifier, with a slow flow of water, the content of salts of nitrogen and phosphorus in the water is more than doubled.

Plant propagation

In order to propagate in a vegetative way a popular representative of the aquarium flora at home, it should create an optimal environment close to the natural one. As a rule, a mustache grows in Vallisneria, which subsequently form daughter bushes.

Young plants can be separated from the mother plant after the formation of several leaflets and root lobes from the daughter plants. Having cut a mustache, it is possible to receive a separate bush ready to independent existence. Grow vallisneria seed method at home is quite difficult. In addition, experts find it impractical because the plant is dioecious. This means that each individual shrub forms male and female flowers.

Food supplements for fish

The presence of copper salts in water, which are sometimes used in the manufacture of preparations against algae and slugs, also does not benefit the vallisneria. And although manufacturers often refute the likelihood of a negative effect of drugs on aquarium vegetation, the reviews suggest otherwise.In particular, after adding Bicillin-5, a medicine for fish, spiral vallisneria, the giant die.

Significance of Vallisneria in an aquarium or pond

The supply of oxygen is the merit of the plant in the exchange processes of the aquarium. Taking useful organic matter from the soil, it creates all the conditions for the full existence of living organisms in the water of vallisneria. Maintenance and care (plant species are numerous, but several of them are primarily in demand), performed in accordance with the requirements of cultivation, will allow the bushes to multiply at an unprecedented pace.

In this connection, the valisneria needs regular thinning of densely growing thickets. It is extremely important to remember that sometimes in shallow ponds or aquariums of insufficient height, the leaves of the plant create an almost impassable green veil, which prevents natural light passage. The solution to this problem is one thing - reducing the bushes of growing vallisneria.

Appearance: Vallisneria is a beautiful shrub with narrow ribbon-like leaves from 10 to 80 cm long. Vallisneria foliage is usually strong and elastic; different shades of green and red. Herbivorous inhabitants of the aquarium are not dangerous, except for digging species that can pull out a poorly rooted plant. Some forms of Vallisneria have very sharp leaves due to small cloves. Therefore, you need to carefully handle it, so as not to cut your fingers.

Salinity of water: from 0 to 20 ppm.

If you have a frame aquarium or bad tap water, watch the rust concentration in it, the plant does not like it. An excess of copper in water also affects the development of Vallisneria. This metal can get into the aquarium together with preparations against snails and algae, as well as with medicines for the treatment of fish.

SPIRAL VALLISNERIA - CONTENT, SPECIES, DESCRIPTION, BREEDING.

Spiral Vallisneria: description and types

In order to somehow revive the artificial reservoir and give it greater similarity with the natural environment of the inhabitants living in it, most aquarists use different vegetation. But it is worth noting that some species can not always create a favorable microclimate, but quite the opposite. Therefore, the ideal option would be to use unpretentious plants, one of the representatives of which is spiral or tiger vallisneria, which will be discussed in today's article.

Description

An aquarium plant, such as spiral or tiger vallisneria, as mentioned above, is one of the easiest to keep. Therefore, it is not surprising that it is highly popular with beginners, and some experienced aquarists will not be surprised by the opportunity to purchase it on occasion.

Externally, this plant is presented in the form of small bushes with long leaves, the size of which varies from 100 to 800 mm. As a rule, its leaves are not only distinguished by high strength, but also by excellent elasticity. And this is not to mention their exterior color, starting from light green and ending in red.

I am glad that this plant does not pose a threat to most of the inhabitants of an artificial reservoir as feed. The only danger for this plant are those fish that can dig them out of the ground. Also note that some species of this plant have sharp leaves. Therefore, it is necessary to handle it with sufficient care not to harm the skin of your hand.

An interesting fact is that under certain conditions, this plant can bloom with small bells that will decorate the water surface of the aquarium.

As for the root system, it is developed fairly moderately. It is presented in the form of elastic roots of a milky-yellow shade, the length of which can reach 100mm in length.

Placing this plant is best in gravel, but for his lack of suitable and sand. The only thing to consider is the permeability of the substrate.

As for the conditions of detention, the most optimal include:

  1. Temperature range within 18-32 degrees.
  2. Low or neutral acidity.
  3. Moderate stiffness.
  4. Salinity range from 0-20 ppm.

It is also particularly worth noting that this plant is categorically bad for both rust and copper in water.

Important! This plant does not require a certain style of lighting.

Kinds

As mentioned above, Vallisneria spiral is one of the most sought after plants today. But It is worth noting that this plant is only one of the representatives of this numerous species. So, besides her in pet stores still sold:

  • Wallisneria nana;
  • Wallisneria natans;
  • giant valisneria.

Consider each of the presented species in more detail.

Vallisneria nana

Wallisneria nana or as it is called this plant - dwarf is found in the northern part of the Australian continent. The representative of this species has a not very long rhizome with shoots coming from it, located on the sides, as shown in the photo below. Its maximum value in an artificial reservoir is about 300-600mm. It is worth noting that this parameter directly depends on the level of illumination in the room and, of course, the internal microclimate in an artificial reservoir.

Quite interestingly, this plant is the owner of 2 different forms of leaflets. So in one case they are quite rigid and their length is about 150 mm. In the second, they more resemble a ribbon. They are also very narrow and their length is 600mm. It is recommended to place it for the design of the rear and side zones of an artificial reservoir.

Although the content of this vegetation does not require much effort, but experienced aquarists recommend placing it in an aquatic environment, the temperature of which does not leave the limits of 25-29 degrees.

Important! This species is more light-loving and long-growing with respect to their relatives.

Vallisneria natans

This plant, the photo of which can be seen below, belongs to one of the varieties of American Vallisneria. It is characterized by not very wide leaves, the length of which can reach up to 100 cm. Also, valisneria not only perfectly harmonizes with other vegetation located in an artificial reservoir, but can also be used by aquarium fish as a refuge or spawning ground.

As for its placement, experienced aquarists recommend placing this plant in the background. The most optimal conditions for its maintenance is to maintain the temperature of the aqueous medium in the range of 20-27 degrees and hardness from 5 to 12 degrees. Also, special attention should be paid to making a regular water change in the vessel.

Giant valisneria

Already, based on the name of this plant, the photo of which can be seen below, it can be assumed that an impressive artificial reservoir is necessary for its maintenance. That is why this plant is not so much in demand among aquarists, unlike its specific counterparts. It is also worth noting that the giant Vallisneria does not stop growing over the course of a whole year.

It is found in Southeast Asia. Externally presented in the form of bushes of impressive size with straight and hard leaves growing on them, the length of which is about 100 cm.

As the soil is best to use sand or pebbles. An interesting fact is that this plant feel excellent in non-new artificial reservoirs, where there are large accumulations of organic substances. Also, the thickness of the soil itself should not exceed 8mm.

Ideal temperature values ​​are from 22 to 26 degrees with a hardness of at least 8 degrees.

In addition, unlike the rest of their relatives, this plant can feel great without regular water changes.

Breeding

Vallisneria spiral or tiger multiplied vegetatively. So, her children appear at the base of the mother and attach at a distance of 50-100 mm. from the main bush. It was there that the small Vallisneria spiral will begin to grow, or, as it is also called, tiger. As a rule, a new plant grows in a very short time period. Sometimes it happens that, not having managed to place one plant in its artificial reservoir, in a few weeks you can be surprised to see that a real cascade has formed in it, different in length and age of the bushes of this species.

Remember that it is recommended to separate rooted children from the mother bush, 3-4 leaflets of which have reached 70 m in length.

Accommodation

As already mentioned more than once, spiral valisneria is designed to be placed near the rear or side zone of the aquarium. This will not only beautifully shade the rest of the vegetation, but also allow you to admire the magnificent green wall over time.

Also a good option would be to place this plant in the immediate vicinity of the filter or the place of discharge of water.

Beautiful algae in the home aquarium

It is believed that algae for aquariums can only bring harm. But there are many types of algae, which are able to decorate the home pond, and bring him much benefit. These species are morphologically close to higher plants. Which algae are perfect for planting in an aquascape without harming living creatures?

Vallisneria

Vallisneria (lat. Vallisneria) - perennial algae, belong to the family Vodokrasovye. These are real aquatic plants, or hydrophytes, which perfectly adapt to life in all freshwater bodies of water. All species of vallisneria are characterized by a thin, long, creeping root system.

  1. Wallisneria nana - the natural growth environment is Australia. The length of the leaves is 15 cm in the wild, but these algae for aquariums can be much less - 30-80 cm. The growth rate is high, with saturated light and water temperature of 20-27 ° C.

  2. Vallisneria americana - differs by a small length of leaves (10-15 cm). Can be planted in the foreground or mid-plan aquascape. The shape of the leaf plates is spiral, so the sunlight plays on them beautifully.

    See what looks like the Vallisneria americana.

  3. Wallisneria natans - characterized by narrow leaves 0.1 cm wide, and 1 meter long, they have 3-5 longitudinal streaks. Vertical streaks are arranged in a chaotic manner throughout the sheet. The birthplace of Vallisneria natans is a flowing reservoir of Central Asia. This seaweed is unpretentious in care, so it may contain novice aquarists. The lighting is moderate. Water temperature for keeping: 18-28oS.
  4. Vallisneria giant Americana is the largest vallisneria. Suitable for spacious tanks with a depth of 50 cm, it is better to plant in the background aquascape. The color of the leaves is dark green. For the development of recommended bright lighting, nourishing soil. So that Wallisneria does not completely cover the surface of the water, it must sometimes be thinned out. Contain better at a temperature of 22-25 ° C.

  5. Vallisneria americana var. Bivaensis is another representative of the Vodokrasovs. The length of the leaves can be 10-50 cm, width 0.5 cm. The shape of the leaf plates is beautiful and curled. It is recommended to land on the average plan, in spacious tanks - in the foreground. For good development, Bivaensis needs rich lighting, unlike other types of Vallisnerias. Suitable for cold water and tropical aquariums, as it tolerates wide temperature ranges.
  6. Tiger Wallisneria Spiral is a breeding breed that was obtained by crossing other types of Wallisneria. It grows quickly, the color is bright green, saturated. Differs stamina and unpretentious content. The leaves have stripes resembling a tiger print. Propagated by vegetative way, due to the division of the side shoots, which were called "arrows". You can keep in water with a temperature of 22-25 ° C, the acidity of the aqueous medium is recommended 6.0-7.5 pH, hardness 5-10o.

Floating algae

Blestyanky flexible, or nitella (an armor. Nitella flexilis) - a floating alga of the Kharovy family. The natural habitat is North America and Eurasia. In leaves palchatorassechennaya form, they are located on a long stalk in verticils. Each verticil has 5-7 stalks. Leaf color can be light green or emerald. In a glossy stalk, the stems are strongly branched, so the algae can swim in the water column in a tangled form. In the tank, the water must be clean and transparent, because the suspended particles are deposited on its leaves. You can keep in moderately warm water at a temperature of 19-27oC. The average hardness of the aqueous medium is acceptable, the acidity is neutral. LED lamps with a power of 0.5-1 watts per liter of water are suitable for lighting. The number of daylight hours is 12 hours.

Riccia floating (Riccia fluitans) - is floating algae for aquariums, which can be let in moderately warm water. In nature, grow in all corners of the planet. Openwork weaves of saturated green color create a cover in the form of islands. The algae has no leaves and stems, as well as a root system. Riccia consists of thallus, small flat plates that are intertwined with each other. Riccia is often used as a spawning substrate for breeding fish in an aquarium, best suited to shelter fry. When the hardness of the aqueous medium is above 8 dGh, the alga grows slowly. Recommended water temperature for content: 20-22 degrees Celsius.

At a low temperature range, it stops growth, a deformation of the structure occurs, which can lead to death. Every week it is necessary to make the replacement of 20% of water for fresh and infused. Riccia floating prefers bright lighting. Be careful if plant species live in the aquarium that do not like bright light. When there is a lack of light, the alga splits into small fragments, begins to rot. In summer, these algae for aquariums greatly expand, preventing the ingress of sunlight into the water.

A cornea, or a rodentum immersed (lat. Ceratophyllum demersum) is a perennial alga that floats on the surface of the water, since the root system is absent. At low water temperatures, begins to descend to the depth of the reservoir, slows down its growth. The stalks are long, the leaves are tiny and needle-like, they can hide small hydrobionts.

Look at how a jagger grows in an aquarium.

These are great algae for aquariums, as they provide shelter for fry. In the leaves of frypokolnika fry will not get large fish, on the leaves there are microorganisms that will be food for the fry. Calfers may be spawning substrate on which caviar will be deposited. Sticky eggs firmly glued to the needle leaves, and not sticky eggs just stuck in them. It is better to immerse the rodentard in a moderately warm or cold-water aquarium, where the hardness of the aquatic environment is 5-15 °, the pH of the reaction is neutral or slightly alkaline. The hornberry likes a large amount of light, therefore the length of daylight hours is allowed above 12 hours a day.

Globular algae

Kladofora spherical, or Japanese marimo (Aegagropila linnaei) - belongs to the Kladoforovye family. It has a decorative meaning for freshwater aquariums. Its structure is a colony of green filamentous algae, which form a dense green ball. The location of the filaments in the colony is radial.
