Java Fern Windelov in Aquarium: Types, Care, Propagation

Java Fern Windelov (Thai fern) is a home aquarium plant, which is characterized by unpretentious maintenance. In nature, there are many varieties that differ in the shape of the foliage. Aquatic plantations grow slowly, but develop evenly throughout the year. Creeping roots attach to driftwood and rocks, forming wide green shrubs. Subject to the rules of cultivation, they become a decoration of any aquarium or artificial reservoir. Suitable for breeding by both beginners and experienced owners.

Java Fern Windelov Habitat and Appearance charateristics

The Thai, or Java Fern Windelov (Microsorum pteropus) is a representative of the order of the Centipede. In the wild, it inhabits the coast and water bodies of the countries of Southeast Asia (Java, Malaysia, Thailand, northeastern India). There are varieties with different sizes and shapes of leaves: narrow, lanceolate, needle-like. The most common is the narrow-leaved.

In a tropical environment, an adult plant reaches its largest size – 50-60 cm.The average height of an aquarium specimen is 20-30 cm.

Elongated roots with filamentous branches (rhizoids) cling to tree parts and stones. The bright green foliage has a lanceolate elongated shape. In a favorable microclimate, plants form dense thickets that stretch to the surface. In the process of prolonged growth, small spores appear on the sheets, changing color to a darker one.

The fern grows in water and on land, does not require intense lighting and frequent CO2 application. It gets along with fish eating green plants. Decorates any area of ​​the aquarium.

Java Fern Windelov benefits for aquarium

Fern is a natural water purifier in a container. In the process of life, it absorbs both useful and harmful substances. It is recommended to plant the plant in the center line as it covers a large area for cleaning.

Fish spawn in the leaves, and viviparous species hide in dense thickets during childbirth. Defenseless males find shelter from predators.

The Thai fern is suitable for creating interesting underwater compositions.

Java Fern Windelov care and maintenance

Microsorum pteropus does not burden the owners in terms of maintenance and care.

java fern windelov care and maintenance

For the normal functioning of aquatic ferns, it is recommended:

  • avoid overheating by lighting fixtures;
  • prevent a sharp drop in temperature in the tank;
  • populate the aquarium with compatible fish species;
  • monitor water quality;
  • timely cut off withered and spoiled shoots with scissors.

With an acute deficiency of nutrients and insufficient lighting, the plant turns pale and slows down growth until a suitable microclimate is created.


The growing tank is selected according to the height of the tropical plant. Bright greenery is suitable for decorating a deep and voluminous aquarium.

Since the species prefers a calm atmosphere, it is recommended to grow it away from filtering equipment. Fragile shoots do not tolerate constant mechanical stress.

To provide each specimen with a sufficient amount of micro and macro elements, it is necessary to maintain a distance during landing – up to 20 cm from each other. Bushy bushes grow more slowly because their roots are intertwined, which inhibits the development of the entire population.


The plant loves soft neutral water without sudden temperature fluctuations. A comfortable environment for the growth of most fern species is a tropical climate with a temperature of + 25 … + 30 ° C. In cool water, the culture slows down development. A suitable hardness value is 0-6 ° dH, the acidity level (pH) is 4-6. It is recommended to replace 15-20% of the total water volume 1-2 times a month.


Most varieties of Microsorum prefer dim artificial or natural diffused lighting. The plant slows down its growth with prolonged darkening. The recommended daylight hours are 10-12 hours. It is recommended to use incandescent lamps or fluorescent lamps with white dim light as lighting devices. The power is selected in accordance with the volume of the aquarium at the rate of 0.3-0.5 W per 1 liter.

An overabundance of illumination leads to the fact that the foliage becomes brown and transparent. When burned, the plates turn yellow and fall off. It is necessary to diffuse sunlight and reduce the intensity of artificial light.

Planting substact

Many varieties of Javanese fern do not require soil and do not need additional fertilizers (fine-grained silted sand is sufficient). Due to the undeveloped rhizome, which spreads over the substrate, the plant is attached to decorative elements, driftwood or coarse gravel.

The following means are used for fastening:

  • glue;
  • fishing line;
  • thin silk thread;
  • harness.

After weighting, the bush easily moves to any corner of the tank.


The intensive development and growth of representatives of Microsorum pteropus requires regular fertilization (at least 2 times a month). Fern receives all nutrients from water. For enrichment, liquid nitrogen fertilizer urea (urea) is used, which is applied at the rate of 10-12 granules per 100 liters. The supply of CO2 and universal mineral compositions when changing the water in the tank has a beneficial effect on the development and color saturation.
Due to the lack of a developed root system, feeding in the form of sub-root tablets will not work.

Java Fern Windelov propagation

Reproduction of tropical ferns occurs in a vegetative way. Daughters with 2-3 leaves are separated from the old bush. Then they are tied to a wooden lath or pebble at a short distance from each other for rooting.

The second breeding method is the formation of young shoots on the leaves of an adult plant. After blackening and dying off of the mother sheet, the layers are separated and remain floating on the surface. After the formation of long floating roots, the seedlings are prepared for planting. To create a dense carpet, a mesh is used to which the roots are densely tied. The growth rate is 2-3 weeks.

The pterygoid and narrow-leaved fern does not tolerate frequent transplants and frequent blowing.

Java Fern Windelov compatible with other inhabitants in the aquarium

The main advantage of the Microsorum family is the specific structure of the foliage (it is believed that the shoots are tough and bitter in taste). This discourages herbivorous species of fish and turtles from eating the fern, so they are suitable for the neighborhood.

The plant gets along well with cichlids, guppies, scalars, apistograms, swordtails and anubias, who love to feast on greens.

It is not recommended to populate fish digging soil into the tank. They easily damage thin roots, slowly destroying the bush.

These varieties include:

  • gold fish;
  • catfish;
  • agamixis;
  • corridor, etc.

Observing the main technical indicators and simple growing rules, the aquarist gets lush bushy thickets and bright decor.
