But the hydrophyte is quite demanding on the conditions of detention, and because of this, grass is not so often found in amateur aquariums. She is not even often found in professional banks. At the stage of buying and choosing an aquarium, you must decide for yourself whether to take this plant or not. If you do not want unnecessary problems, then do not torment the plant and yourself.
For Rotalla Wallich, you need a tropical aquarium with a water temperature of at least 22 degrees Celsius. If the temperature of the medium drops below 22 degrees, the hydrophyte will slow down its growth and simply die over time. Water should be soft and have a slightly alkaline environment. Water should also be fairly clean and free of impurities. Each week it is necessary to replace about 15% of the total.
In order for your rotala to have a beautiful and healthy appearance, and the color of the leaves to be reddish, bright lighting needs to be organized for it. But do not think that you need to quickly install the aqua near the window, since from direct sunlight on the aquarium, algae may appear in it. The power of the lamp should be at least 0.5 W per liter of volume. Daylight hours from 12 hours. You can most likely find this plant in online stores, but you can also search your acquaintances for aquarists who grow aquarium plants.

This species somewhat resembles the river Mayak in its structure, but differs from it by the color of the foliage - most often it has a reddish-brown hue. In nature, it is most common in the region of Southeast Asia, covering India, Malaysia, and also part of China. Most often, this plant can be found in the swamps of these areas. It can live both under water and on land - in both cases, the size of the stem rarely exceeds 40 cm. At Rotala Wallich, the structure of the surface and underwater parts of the plant is different - the surface leaves are linear in structure and usually have a greenish-brown tint, while the underwater part of the stem is covered with many threadlike leaves of red color.
In the aquarium, this tender plant lurks many dangers: improperly selected water parameters, lack of lighting, the presence of undesirable chemical additives, herbivorous fish ... It is deservedly considered one of the most difficult plants to care for.
Since the root system of the grass is very weak, the level of siltation of the substrate does not play a key role. The most acceptable substrate is sand, laid in a layer of several centimeters. Rotala Wallich propagates only by cutting the stem. It can be grown both in greenhouses and in paludariums. In such conditions, the grass shows high growth rates.
It is enough just to take the stem from the plant from the aquarium and add it to the substrate, and then pour a couple of centimeters into the water tank. Such conditions provoke the plant to form air shoots. If the ambient temperature is in the range of 26 - 30 degrees, these air shoots are actively growing. Subject to bright lighting and nutritious soil, rotala will always be magnificent and beautiful.
When a plant grown in a greenhouse grows stronger, it can be transplanted into an aquarium. The adaptation period is quite decent, in just a couple of days, the hydrophyte will begin to grow again actively. But Wallich tolerates the haircut and other external influences of Rotala's hard. If you cut the upper part of the stem, then the lower part will begin to branch and will die in the future. But if she gives the first side shoot, she can be easily trimmed. Cut stems can be planted next to the mother, so you slightly tighten the bed. To get a bright crimson leaf color, the nitrate level in the water should not exceed 10 mg / l, and the phosphate level should not exceed 0.5 mg / l. In addition, you will have to constantly monitor the level of iron, sometimes you have to pour it. This is done so that calcium can go directly to the rhizome of the plant.
Rotala Wallich does not tolerate the presence of any chemical additives in the aquarium - if it becomes necessary to add them to the aquarium, a plant transplant may be required.
In the summer, inflorescences with small purple or white flowers may form on the surface of the plant.
The root system of this plant, like the entire Rotal genus as a whole, is very poorly developed - in principle, it is able to exist, not rooted in the ground, but simply floating in the water column. If it becomes necessary to root Rotala Wallich, it is best to use fine sand as a layer of 2-3 cm as soil. A small siltiness of the soil will benefit the plant, however, it usually does not need additional fertilizing, unless the addition of iron ions will improve the intensity of Rotala's color.
The most profitable Rotala Wallich looks, landed in dense groups. The red color of the foliage, especially saturated with good care, goes well with green plants, giving the aquarium a bright, exotic look.
In addition to the aquarium, this plant is suitable for cultivation in a paludarium. It is enough to place the plant in fertilized soil, recessed a couple of centimeters in water, and at a temperature of 26-30 ° C it will quickly give air shoots. In the future, the plant can be transferred to the aquarium, where, after a brief period of adaptation, it will continue to grow as if nothing had happened.
Propagated by cuttings. The separated part of the plant can be left to swim in the water column or immediately rooted in the ground - in the latter case, it will show slightly higher growth rates.
