Vesicularia Dubyana. “Singapore Moss”

Vesicularia dubyana. “Singapore Moss” growing area

Many species of water moss live in slowly flowing and standing water bodies. Among them there are plants of the middle strip, well growing in cold-water aquariums. Others are tropical plants requiring a higher temperature and clear, clear water. These include Singapore moss - a very beautiful tropical plant that enjoys well-deserved love of aquarists for their beautiful appearance and a lot of useful qualities.

Vesicularia dubyana or “Singapore Moss” is often called Javanese moss; in stores and in the bird market it can also be represented as Javanese moss. Which of the names will be more correct, one can argue ad infinitum. But there is also a moss “Taxifillum barberry” Latin name: (Taxiphyllum barbieri) “Java Moss”. It is also often called “Javanese”, the Latin name of this moss “Taxifillum burberry” is difficult to remember, therefore it is often called “Java Moss”, that is, Javanese moss. Therefore, in order to avoid confusion in this article, we will adhere to the Latin name of the vesicular: “Singapore Moss,” that is, Singapore moss.

Growing Range Singapore Moss

This plant is widespread in the tropical part of Southeast Asia. The growing places of Singapore moss are small non-perennial ponds. Here it can be found almost everywhere near the coast at a shallow depth. Singapore Moss grows on snags, stones, flooded stumps and trees, forming dense green thickets.

Appearance of Vesicularia Dubyana

Vesicularia Dubyana has thin, highly branched stems, strongly intertwined. Their length reaches 17 cm. The plant has needle-shaped leaves. Green leaves up to 2 mm in size densely cover the stems. This moss looks like a ball of tangled threads of dark green color. Old leaves have a dark green tint, young leaves are light green.

Singapore moss is growing slowly. Its stems randomly branch, often grow rapidly and form continuous thickets. This plant is very unpretentious in content, and is also characterized by extreme shade tolerance.

Singapore moss belongs to lower plants that do not have a root system. It is replaced by rhizoids - root-shaped processes that form on the lower part of the stems. Rhizoids have a reddish-brown tint. They are so small that they are almost invisible to the naked eye. With the help of rhizoids, the plant can be attached to any surface. It is quite firmly fixed to stones and snags. In the process of rooting, this species places increased demands on the composition of water and lighting. After the plant has released rhizoids and fixed on the substrate, its growth rate increases, as evidenced by the appearance of new shoots of light green color. A rooted plant grows beautifully and magnificently. The growth rate of Vesicularia Dubyana is almost the same throughout the year, seasonality is absent.

This plant is drowning under its weight, so it is not necessary to press it to the base.

Content in the aquarium Singapore moss "Vesicularia Dubyana"

Water temperature greatly affects the growth and development of Singapore moss. The best temperature for its maintenance is in the range of 24 - 28 degrees. In cold water below 22 degrees, this plant practically does not grow, but can maintain its former appearance for a long time.

Singapore moss can withstand various water chemistry. It withstands various water hardness. He is also able to tolerate salinity up to 3% for a long time. The acidity of water slightly affects plant growth. However, the following water indicators are comfortable for Vesicularia Dubyana: acidity - 6.0-6.4, hardness - 6 degrees.

A vital factor for Singapore moss is the availability of clean, clear water. This plant does not tolerate muddy water, which pollutes it and interferes with normal nutrition. This species does not need regular water changes; it tolerates old water well. In the presence of dirt and suspended particles in the water of the aquarium, bushes of Singapore moss are easily contaminated and lose their attractive appearance. In addition, dirt clogs the pores of the plant, which interferes with normal gas exchange. In this case, the plant suffocates. To prevent this from happening, Vesicularia Dubyana should be washed periodically carefully.

Intensive lighting is not required for the maintenance of the plant, its nature is also not important. It is necessary that the daylight hours for him be at least 8.5 hours. In an aquarium where Singapore moss grows, daylight hours should be determined by the needs of the rest of the plants. It is important that the lighting is not too strong or prolonged, since in this case there is a risk of the propagation of green algae. Settling on the branches of Singapore moss, they can cause its death. If the plant is affected by simple algae, it is recommended to remove the affected part of the bush. Otherwise, the parasite algae will cover all the stems of the plant and destroy the delicate moss.

The shade tolerance of this plant is amazing. With such low light when no aquarium plant survives, Singapore Moss can live and grow for months. With sufficient lighting, this plant begins to branch, forming dense thickets. Its coloring becomes saturated and very attractive.

This plant responds well to the addition of peat broth or tropical black water to the water. At the same time, its growth accelerates, it acquires an amazing emerald hue. To apply special fertilizers to the soil or water for this plant is not required.

Vesicularia Dubyana is preferably kept in aquariums where there are no large fish that dig the soil or can damage its bushes. It is also undesirable to arrange a direct purge of water from the compressor in these aquariums. A strong current of water helps to raise suspended particles from the bottom, which pollute the moss, settling on its stems. At the same time, even good filtration of the water does not save the plant from pollution. Singapore moss is best grown with a very low flow of water and a small number of small fish.

In aquariums that contain Singapore Moss, fish should not be treated with tripaflavin. When this drug is added to the water, the plant dies.

This species is easily propagated vegetatively. It should be very careful to less injure the bush, to separate the overgrown part from it. A new plant can grow even from the smallest piece of moss.

Vesicularia Dubyana is a very good spawning substrate for various species of aquarium fish. Small haracin and carp species willingly spawn in the presence of dense thickets of moss in the aquarium. In such aquariums, caviar is well preserved, fry develop from it, which for a long time take refuge in the green interweaving of moss stems. Fry of viviparous fish also find shelter here. In the thickets of Singapore moss, a favorable environment is formed for the growth and development of fry. Here, water is rich in oxygen and in it there are large quantities of unicellular organisms and small plankton, which serves as food for fry. However, moss should not grow uncontrollably. It is necessary to monitor its growth and adjust it, otherwise the aquarium may be so overgrown that moss will interfere with the circulation of water and even hamper the movement of fish.

Decorative properties of Vesicularia Dubyana

Such a widespread aquatic plant as Vesicularia Dubyana is not always correctly used to design aquariums. Often the aquariums that contain this plant have an unattractive appearance. In order for moss to become a real element of decoration in the aquarium, you must be able to properly place and strengthen it.

Moss that forms openwork thickets is inappropriate to place in the foreground, because it will close the review. It is good to place it in the background to decorate the back wall of the aquarium or in the middle plan attached to snags or stones. Moss bushes look very good in the corner of the aquarium. They can decorate various decorative elements or hide the tubes of aquarium filters in their thickets. Moss looks equally good in both large and small aquariums.

Singapore Moss grows in different directions: horizontal and vertical. After fixing a piece of moss in a constant place, one can observe its growth and development. At first, not yet rooted moss releases the stems to the sides and down. Thus, it overgrows the substrate and provides a reliable connection with it. Then, when the plant is already firmly attached, its shoots grow mainly in the sides and slightly up. At this time, the moss bush is gaining biomass. It acquires a layered and arched structure. After significant growth in the horizontal direction, shoots appear, directed vertically upwards. This process can be observed for several months if the moss remains alone in one place.

Vesicularia Dubyana has no roots, therefore, does not require planting in the ground. Rhizoid moss attaches well to aquarium decorations. It can be especially firmly attached to an object with a porous surface. Therefore, this plant is very often placed on various interior aquariums: stones, snags, lava.

When creating a decorative element with attached moss, it must be borne in mind that the base for it must be strong, so that later it does not have to be separated from it by an overgrown bush. This will negatively affect the development of the plant and may even lead to its death. If the moss is supposed to grow to driftwood, it should in no case be rotting.

When creating a decorative driftwood, it is necessary to spread the moss on its surface with a very thin layer and evenly. Growing tight lumps is not recommended. Then it is wound to the base with a thin fishing line. Sometimes a cotton thread is used for this. If a fishing line was used to mount the moss, it can later be removed. It is not necessary to remove the cotton thread, since it rots over time. Sew Singapore Moss to the base must be very tight. Gaps should not be left, since in these places the moss will be poorly fixed. The whole process must be carried out very carefully and carefully so as not to damage the delicate branches of moss and in the future to achieve the desired decorative effect.

By placing moss on the base, you can combine it with other plants. Sometimes driftwood is decorated with moss in combination with ferns bolbitis or microzoriums, as well as anubias. At first, plants based on plants look very unattractive, but this is only the first time. After they start to grow, the picture changes. And when the plants grow well, an amazing picture of wildlife is created - a real work of art. But this happens only when the plants do not disturb and do not interfere with their growth and development.

The Singapore Moss adhered to the base rests on it so tightly that it can be moved, moved to another place along with the base. This is very convenient when changing the interior of the aquarium. It is used to decorate ceramic pots, where other aquatic plants and many other decorative elements of the aquarium grow. In order for the moss to form beautiful thickets, it is only necessary not to disturb it for a long time.

Glades of moss also look very beautiful in aquariums. In this case, moss covers the soil in a continuous layer. To do this, you need to have a moss bush, attached to a flat stone. As it grows, you need to trim too long branches pointing up and slightly tear apart dense tangles in all directions. In this case, the moss will grow to the sides and cover the soil. Quick coverage of the soil does not work, because moss grows slowly. However, over time you can get a very beautiful green meadow if there are no large fish digging the soil in the aquarium. To simplify the process, you can use the grid. Moss twigs need to be laid out on the ground and covered with a net. The net will strengthen the moss at the bottom, and when it begins to grow, it will hide the net.

Vesicularia Dubyana can be used to decorate the back of the aquarium. In this case, you can also use the net to strengthen the moss on the back wall. Here you can combine moss with ferns. When plants grow, an amazing effect is created. It seems that plants grow from the wall, which looks very impressive and original.


Javanese moss - belongs to the Hypnaceae family. Grows in tropical areas of Southeast Asia. Other names for this plant are Singapore Moss, Java Moss, Vesicularia dubyana. Its height is about 5 cm. The optimum temperature for its development is from 18 to 30 ° C, the required water parameters are PH from 6 to 7.5, dKH, from 2 to 15 °, lighting is 0.15 W / l

  • Quite often, it is used as a decor. This plant looks like a dense and chaotic binding of thin stems that are highly branched and covered with leaves that have a dark green color. The size of the leaves is from 1 to 2 mm. At first glance, this plant has only leaves and a stem. With the naked eye it is almost impossible to make out
  • the numerous rhizoids that a plant needs to attach to a variety of surfaces. They are very small. The chaotic form of Javanese moss is deceptive. When a piece of the plant is attached to a permanent place and not disturbed for a couple of months, you will notice that the stems develop in different ways. The stems, fitting the substrate, stretch down and to the sides. Thus, they reliably connect to its surface. After the plant is firmly attached, it begins to give numerous shoots, which are directed slightly up and horizontally. Outwardly, the entire moss has the form of many layers arranged in the form of an arch, relative to each other. When the plant acquires the desired amount of biomass, stems begin to grow, which are directed upwards.

Appointment in the aquarium

Javanese moss fell in love with aquarists and for its versatility. He not only performs a decorative function, but also has a number of useful qualities.

Thickets are a safe place to spawn fish that lay eggs on their leaves. For this reason, very often Java moss is used in spawning. Even in a general aquarium in case of spontaneous spawning, some eggs are preserved, since the “parents” and other inhabitants cannot get close to them and eat them. If necessary, the bushes selected by the egg-laying fish for spawning are transferred from a common tank to the seedling, where the eggs develop in safety. As a spawning medium, thickets use barbs, haracin fish species, and representatives of the killfish family.

The use of moss is obvious for young. Due to the abundance of ciliates in the thickets, it is the main food store for young fish and shrimp.

The decorative function is not inferior in importance and provides great opportunities for the expression of design ideas. Java moss was one of the first to be used to create aquascapes.

Further information on Vesicularia dubyana (Javanese moss):

Javanese moss is a popular unpretentious and undemanding plant to the state of water and lighting.
Javanese moss (vesicularia dubyana) is easily attached to any surface, so it is suitable for decorating stones and snags or masking aquarium equipment. The moss is usually fixed with fishing line, which is then removed.
With high humidity, the plant is suitable for growing in a terrarium.
It serves as an excellent refuge for small fish and fry. Also used as a substrate for spawning.
Propagated by vegetative fragments of shoots.

How to care for Javanese moss ?!

It all depends on your understanding of the design of the aquarium. Regular pruning of moss will give a neat appearance and will allow you to get almost any shape, especially with strong lighting and the presence of nutritious fertilizing in the aquarium. But, you are free to not interfere with the growth of Javanese moss, which will give a wild pristine look to your design.

In strong light, your problem may be algae that settle on Javanese moss. Removing them can be your nightmare.

Use a toothbrush to wrap algae strings and remove them from the aquarium. Strong pull is not worth it, you can damage or tear Javanese moss from its place.

Javanese moss is unique in that you can simply design an aquarium, fully reproduce the biotope of nature or provide a reliable shelter for fry, give a sense of age to your aquarium, snag or stone.

By the way, many species of aquarium fish prefer to lay their eggs on Javanese moss., if available.

  • Optimal water temperature for Javanese moss should be + 23 * C + 30 * C (the plant is from the tropics). If the temperature in the aquarium drops lower than + 22 * ​​C, then the “Javanese” will simply cease to grow, and if it is even lower, it will certainly “give up”.
  • Regarding the acidity and hardness of water, it is better if the acidity of the water is between 5.0 and 8.0 Ph. And the hardness of the water is really indifferent to him: he feels great both hard and soft water, as well as brackish. The only requirement is perfect clarity and transparency! In dirty muddy water, moss forms on the moss, which interferes with the normal nutrition of the plant, which is very bad.
  • Also javanese moss prefers a small flow of water. Therefore, if possible, be sure to create such a flow.
  • Lighting for Javanese Moss - the tenth question: the plant tolerates the complete absence of light without problems! But in bright light, its growth is significantly accelerated, and the plant itself acquires a very juicy color. But nevertheless, the optimal lighting is moderate.
  • Soil is not needed at all: Javanese will grow perfectly even on “bare” glass!

Landing procedure

Before the procedure, be sure to disinfect the potassium permanganate capacity of a 3% solution. These manipulations are required for the safety of aquarium inhabitants. Then a mossy layer is already placed on the bottom surface - whether it is soil, stones or driftwood. In this case, the layer must be thin, otherwise the rhizoids may die out.

Planting Javanese moss is very simple if you use a fishing line or net. The fishing line of the "plantation" is wound to the selected surface for a week or just attach the plant with some kind of load for the same period.

If you want to create a beautiful aquarium background from the plant, then they take a grid with large cells and perform the following actions:

  1. They make two workpieces of the same size from it (they must correspond to the dimensions of the back wall of the tank).
  2. Then they proceed to the collection of the “sandwich”: on the first part of the net lay the branches of moss, then cover it with the second part and tie it up with fishing line.
  3. Then the resulting frame is fixed to the rear wall of the tank using suction cups. There should not be any gaps, otherwise small fish can get into them and get confused.

In general, Javanese moss is an unpretentious plant, suitable for decorating any aquarium. Its ability to live simultaneously in air and in water attract many, in addition, you can use the plant to create a beautiful transition from the sand zone to the plant site.

The plant is suitable for beginnerswishing to practice compositional techniques in practice. After all, the hassle of keeping Javanese moss is a minimum, but aesthetic pleasure is a maximumPropagation

    • Javanese moss reproduction: by dividing its colony into parts. Javanese moss can be cultivated not only in an aquarium, but also in a greenhouse or greenhouse. The surface form of Javanese moss is more decorative than aqua. It is better to dry the plant from time to time to fight against aquatic plants that appear on its leaves.
    • Placement, planting in the aquarium: in the aquarium it performs two functions - utilitarian and decorative. Javanese moss is a great assistant for fish farming. Due to its own bast-like structure, the plant is excellent for spawning many fish species. As for the decorative ability of Javanese moss, the ability to introduce it can be limited only by the aquarium’s imagination and experience. A common method is moss on stones and snags. On the support, the moss is strengthened with a narrow fishing line or cotton thread, which rots over time. The plant should be laid very neatly, twig to twigs in one layer, and winded very firmly, without gaps. The first time the moss is not very neat and looks great, but after a month it takes on a well-groomed appearance.Also Javanese Moss You can decorate the back wall of the aquarium by placing it behind a fixed coarse mesh made of a small fishing line. In the same way, you can decorate the bottom of the aquarium.

    Designer finds

    Proper design of the aquarium helps to achieve an amazing visual effect. Javanese can decorate the back wall of the aquarium.

    • To do this, you need to measure the wall area.
    • Then you need to pick up a plastic mesh of the same size. Rinse the net thoroughly with water before use.
    • Javanese moss is attached over the entire area of ​​the net with a synthetic thread or thin fishing line.
    • Suction cups are placed at all corners of the grid, with the help of which it is installed on the wall of the aquarium.
    • The net is gently lowered into the water and attached to the wall of the aquarium using suction cups.

    Although the back wall of the aquarium is often chosen for decoration, moss can decorate any wall by placing it under a tightly fixed mesh.

    For the second method of decoration, you need coconut.

    • It is necessary to break off the top of the nut, and pour coconut juice.
    • Divide the coconut into two parts, and clean each of them from the pulp.
    • Next, cook the purified half in boiling water for half an hour.
    • Let the coconut cool and drill a few holes in the shell with a drill.
    • Fasten the Javanese with synthetic thread or fishing line and place the half in the aquarium.

    Coconut will be not only a great decoration element for the aquarium, but also a home for fish!
