Therefore, before deciding to use rotala to design your aquarium, think about whether you are ready for this crucial step.
Rotala Macrandra is an aquarium plant native to India. At home, it can be found growing along the coast in silty soils. A long-stemmed plant, under water, grows straight up, turning bright red. It spreads over the surface of the water and turns green. The plant reaches a height of 20-30 cm, is often used in nano aquariums as a background plant.
Despite the fact that rotala macrandra is a rather difficult plant to maintain, it is quite easy to purchase, and the price is quite low.
In addition to the traditional standard sample of rotal macrandra, other varieties of this plant are also known:
- rotala macrandra “green” (Rotala macrandra “green”);
- rotala macrandra narrow-leaved (Rotala macrandra “narrow leaf”);

- rotala macrandra green narrow-leaved (Rotala macrandra “green narrow leaf”);

In home aquariums in the post-Soviet space, Rotala is rare, and this is due primarily to the low information content of domestic aquarium lovers about this plant, as well as the complexity in the content of this plant.
Temperature. To maintain rotala, the temperature in the aquarium must be maintained in the range from 22 to 28 ° C, and priority should be given to the upper bar.
Lighting. Rotala requires bright lighting, as in bright light, the leaves will acquire a reddish, more decorative shade. The light period of time should be at least 12-14 hours a day. Sunlight is allowed, but no more than 3 hours a day. With a lack of light, the rotala stretches out and looks weak and pale.
Water. Water for Rotala should be soft with the presence of peat (you can use a peat filter). We change the water once every two weeks up to 30% of the volume of the aquarium. Keep an eye on the water level in the aquarium, the level should not be lower than the plant (the plant should always be in the water).
Priming. For normal growth of rotala, the soil in the aquarium should be natural, nutritious and without dyes. Various pebbles with the addition of peat or a small amount of clay are suitable as soil. Pouring soil into the aquarium is enough up to 3cm, as the rhizome is weak and small.
Fertilizer. For rotala, the use of mineral fertilizers is allowed, but it is important to remember that the dosage should be two times lower than for other plants.
Important! The plant can be planted only in areas with a weak current - a rapid flow of water can damage its fragile leaves or tear it up to the root.
For rotala, as well as for all long-stemmed plants, propagation by cuttings of the stem is typical. The length of the cuttings should be at least 7-10 cm, otherwise they will grow extremely slowly. If you take stalks from the middle part of the stem for propagation, make sure that a lateral shoot is definitely formed.
Carrying out any manipulations with Rotala, do this very carefully. Her delicate leaves respond poorly even to a light touch of her fingers. Therefore, try to minimize the time the plant spends in the air during transplantation.
If you grow rotala in a container with a low water level, make sure that its top is not above its surface. Terrestrial shoots, once in the air, will quickly lose their decorative properties. Also, once out of the water, the plant can bloom, which is also not the best way to affect its appearance.
Leaves rotala leafy have an ovoid shape with wavy edges and reach sizes up to 5 cm in length and 4 cm in width, are located on a long stalk opposite each other. The bottom side of the sheet is colored in purple, but the color of the top side varies from red to green. At rotaly large-stamen stems are slightly branched, long, growing vertically and reaching up to 20-25 cm in length. Rhizome creeping with a large number of leafy buds. The plant blooms in small pink flowers.
Rotala coarse - a real decoration aquarium. As if varnished, oval purple leaves make this variety rotalsleafy one of the most beautiful among aquarium plants. Plants should be placed in groups in the side or foreground aquarium. Only the groups should not be too dense, otherwise the lower leaves will be in the shadow of the side shoots.
