Thai fern (Microsorum pteropus), species
A popular aquarium plant, known in wide circles of aquarists under the name of Thai fern, exists also under the name - Javanese fern. To avoid confusion, we are talking about the same instance. The homeland of this representative of aquatic flora is the tropical regions of Southeast Asia. Thai fern - these are several types of ferns, which in turn include varieties, often existing due to the painstaking work of breeders.
Thai fern is easy to maintain. The most comfortable water temperature for almost all types of microsorum is 24 degrees, lighting, with rare exceptions, is used from moderate to bright. The Thai fern has a beneficial advantage - all its species grow well on surfaces unsuitable for other plants. It can be driftwood, reiki and even stones. The type of aquarium substrate for microsorum does not matter, since its root system is located on top of the soil. Fern receives nutrients from water, therefore it is always glad to mineral top dressing and carbon dioxide. This has a beneficial effect on its development.
Microsorum is propagated by a vegetative method. The root system is neatly divided and several seedlings are obtained, ready for planting, on which leaflets must be present. When dividing the bush, and just when caring for the plant, you need to remember - fern is a fragile plant, especially large bushes, therefore careful handling is required. In the first month after planting, the plant develops the root system and only then the leaf, so sometimes it seems that the plant has not taken root. Some subspecies of the Thai fern reproduce by spores. Young microsorum is separated from the main plant and rises to the upper layers of water, where it is overgrown with the root system, and then sinks to the bottom.
One of the main types of Thai fern is considered to be Thai narrow-fern. In aqua design, both the species and its varieties are most often used with snags. For the design of planted aquariums, the Thai ferns themselves are a wonderful find, and the Thai narrow-leaved is especially popular due to its thin branching leaves that can create images of a fabulous underwater forest.
To the narrow-leaved Thai ferns, the most recently prevailing popularity is the Filipino narrow-leaved. The leaves of this wonderful specimen are narrow, corrugated, captivating with their grace. It lives well in salt water. This fern grows faster than other species and can reach 40 cm. The plant does not tolerate suspension in water.
To design grottoes in aquascaping, they use a pterygoid trident (microsorum pteropus Trident), a plant with thin green leaves, elongated, resembling a trident. This fern grows to 30 cm. The porous surface for rooting the trident is selected, and the water is salty. It differs from other species in that it prefers low light. Moreover, it is recommended to shade it, planting floating bushes on the surface, which will serve as a trident light filter.
Another species that deserves close attention is Mikrosorum Windelov. This fern is a breeding development, which is a hybrid of the Thai fern. The external data of this microsorum are fundamentally different from their analogues — oblong branched, as if the juicy-green leaves cut through the edges do not differ in height, only 20 cm. A beautiful bush can be grown in bright light, regular filtration and water circulation. Fern grows rapidly, therefore, periodic pruning is required.
One can not ignore another variety of large-leafed Thai fern - Thai red. This plant is characterized by the fact that its young leaves have a reddish color. The growth of the leaves is accompanied by a change of color to the usual green. The shape of the leaf is longer and wider than usual.
Speaking of the rare and beautiful species of the Thai fern, it is worth mentioning the pterygoid undulate. On the long rhizome of this species of large-leaved fern, bushes with long wavy leaves alternately grow. Fern grows slowly and is a valuable find for the design of the background of the aquarium.
Often, the design of the composition involves compact plants. Among the Thai ferns there are some. Smaller than the usual pterygoid - Latifolia, and even less, does not reach 10cm - Narow.
