Cryptocoryne reverse spiral (Cryptocoryne retrospiralis)
Cryptocoryne retrospiral (Cryptocoryne retrospiralis) - grass for the aquarium from the genus Aroid. This is a fairly common plant for aquariums.
The leaves are oblong and have a corrugated structure. The color of the leaves can vary from dark green to olive. With conscientious care forms a thick green "jungle".
The plant itself grows quite large, about 45 centimeters, because of this it must be planted along the rear septum at the aquarium. Due to the voluminous parameters of the bushes, this cryptocoryne is grown, as a rule, in large aquariums. This plant has a very rapid growth under ideal conditions. This cryptocoryne can be attributed to undemanding aquarium plants.
Maintenance and care
This plant is ideally suited for growing moderately heated aquariums, with a water degree of about 25. But if the temperature is below 20, then it immediately slows down its development. And if the water temperature is about 28 degrees, it forces growth. Why add auxiliary mineral substances (top dressing).
For a plant, a slightly acidic initial reaction of the medium causes a cryptocorin disease. And here even the most insignificant pH level may result in the dropping of almost all leaves. The most constant growth occurs only in water with an indifferent reaction and hardness of more than 6. It is such water that has its distinctive feature a more reliable pH and even its smallest micro-vibrations will not cause damage to the plant.
Cryptocoryne is absolutely not picky about the light. It tolerates prolonged shading without difficulty, however, at the same time, the leaves fade significantly and their tuberosity is destroyed. When artificial light occurs, fluorescent bulbs are put into operation. Also, for cryptocoryne, natural lighting is desirable. The duration of daylight hours, as traditionally, is at least 12 hours.
For the safe breeding of cryptocoryne, a special rather highly nutritious soil is needed for aquariums. In scarce or fresh ground, multiplication of the plant. To speed up the hydrophyte adaptation, peat and clay are added to the soil. For a normally functioning cryptocoryne improvement, the aquarium base is a valuable role. Soft soil with small particles in the affirmative effect on the improvement of the rhizome. If the soil is solid, then the roots will climb out. Cryptocoryne has a rather poorly developed root system, because of this, the soil layer in the aquarium should, if possible, be no more than 6 centimeters.
The cryptocoryne reverse spiral multiplies merely by the vegetative method, throwing sprouts on its rhizome. And if you cut off the original plant with the tip of the root, then a young plant will be born on its remaining part. If you decide to separate the shoots from the mother plant, then they must be perfectly developed, since in the newly-found place they will interrupt their growth for a long time. And if the degree of water is not large, the lighting is inferior and scarce soil, then they will completely die.
Safely cryptocoryne is grown in paludariums. But in the air, its leaves are radically smaller and the tuberosity disappears. But under the conditions of the paludarium, the plant multiplies and grows at lightning speed. Excellent conditions of detention, with an air temperature of about 27 degrees and excellent lighting, cryptocoryne blooms, but it is worth noting that under unnatural conditions, seed production does not produce.
