Rotala krupnotychinkovy or rotala krasnolistnaya (Rotala macrandra)

Rotala krupnotylinkovaya (Rotala macrandra) or, as it is also called, Rotala red leaf aquarium plant of the family Derbennikovye (Lythraceae).

In natural habitat Rotala krupnotylinkovaya lives in coastal areas of water bodies of China and India.

Leaves rotary red leaf have an ovoid shape with wavy edges and reach sizes up to 5 cm in length and 4 cm in width; they are located on a long stem opposite each other. The underside of the sheet is colored in purple color, but the color of the upper side varies from red to green. Have large-mouth rotary stems are weakly branched, long, growing vertically and reaching up to 20-25 cm in length.

Rhizome creeping with a large number of leaf buds. The plant blooms in small pink flowers.

Rotala krupnotylinkovaya – the most real decoration aquarium. As varnished, oval purple leaves make this variety rotals red leaf one of the most beautiful among aquarium plants. Plants should be placed in groups on the side or foreground. aquarium.

Only groups should not be too dense, otherwise the lower leaves will be in the shadow of the side shoots.

Rotala red leaf, unfortunately so capricious and demanding in content that not every aquarist can create the necessary conditions. Sometimes aquarium for content of rotala need to be specially equipped. Grows in tropical conditions aquarium with high water temperature (27-30 ° C).

At temperatures below the recommended, even at 26 ° C (!), Growth almost stops, the old leaves quickly decay, and the young shallow. Water hardness for content This plant is recommended in the range of 2-4 °, but the henta well tolerates tougher water. The active reaction of the water should be slightly acidic or neutral.

Good development aquarium plants regular replacement of water (frequency approximately once every two weeks), as well as the addition of peat extract will contribute. In addition, CO2 fertilizing is recommended. poorly rotala krasnolistnaya tolerates the presence of chemicals dissolved in water, for example sodium ions, therefore the addition of baking soda or salt is undesirable.

For content of this aquarium plants need bright enough lighting, when casting rotals red leaf and acquire such an attractive red color (from which the second name of the plant derives). The light source must be placed directly above the plant, very useful lighting direct sunlight for 2-3 hours per day.

Combined light from fluorescent lamps and incandescent lamps can be used as artificial lighting: the former as a source of intense diffused light, the latter as a source of rays in the red region of the spectrum. Light day for rotals large-tongue should not be less than 12 hours.

But with such a bright light you need to protect aquarium plant from the blue-green algae, which are the most dangerous for him. The plant has a very poorly developed root system.

Additional roots are formed on the stalks creeping near the water. Rotaa krupnotylinkovaya can stay and floating in the water column, but in this case its growth slows down and gradually degradation occurs. Unrooted stems die with insignificant deviations of water parameters from optimal conditions.

Therefore, it is recommended to plant the plant in the ground, which should not be silted, but remain sufficiently nutritious. In the new soil, you can add peat and clay in small quantities. Since rhizomes rotary red leaf gentle, then large-sized river sand, which is spread with a layer of up to 2-3 cm, is best suited as a substrate.

Mineral fertilizers as a feed for this aquarium plants It is necessary to make it with great care, as the plant reacts extremely negatively to the slightest excess of the dissolved salts in the water. The concentration of mineral feed should be several times less than recommended for others. aquarium plants.

In addition, it is better to feed in parts in several stages during the week.

Like any other representative of long-stemmed plants, rotala krupnotylinkovaya breeds in artificial conditions by cutting the stem. Shanks taken are 7-10 cm long, because the shorter ones begin to develop more slowly.

A stalk taken from the middle of the stem must necessarily have a lateral shoot formed. Rotala red leaf is very sensitive to touch, in particular to the touch of fingers, therefore the treatment of this aquarium plant should be as careful as possible.

Plant as little as possible should be on the air during transplantation. With breeding at aquarium Avoid escape of shoots to the air, in this case shoots large-mouth rotary loses all its appeal and beauty.

In addition, the plant in ground conditions produces flowers, which is also negatively displayed on its appearance.
