Cryptocoryne aponogenolistnaya (Cryptocoryne aponogetifolia) is an aquarium plant of the Cryptocoryne genus (Cryptocoryne) of the aroid family (Araceae).
In natural conditions Cryptocoryne aponogenolistnaya grows on the Philippine Islands, in rivers with a rapid flow. It grows underwater, at a depth of 2 meters, forming dense thickets. The plant prefers sand and pebble soil or weathered limestone soil.
It can grow both in direct sunlight and in shady places. Cryptocoryne aponogenolistnaya It is considered to be the most beautiful among the representatives of its kind.
Cryptocoryne aponogenolistnaya – a large plant with light green, corrugated leaves. Under the current favorable conditions, the cryptocoryne in height can reach 50-60 cm, for this reason, this plant requires aquarium big size.
Cryptocoryne aponogenolistnaya very demanding maintenance aquarium plant. AT aquarium It should be placed closer to the center.
Grows evenly throughout the year. For content aponogenic cryptocoryne suitable exclusively tropical aquarium, the water in which has a temterature of 24 ° C and higher. In the case of a decrease in the temperature of the cryptocoryne, the process of dropping the leaves begins, and in young leaves the leaves become deformed.
The water hardness in the aquarium should be between 8-16 °, and the pH level – 7-8. When the content of cryptocorynes in soft water with a weakly acid reaction is not a big difference in the development of the plant is visible, however, often when changing water there is a shift in pH.
In this case, the leaves of cryptocorynes break up, turning into a jelly-like mass. This phenomenon is called cryptocorynous disease. Experienced aquarists do not recommend changing the water frequently, if there are cryptocoryne in the aquarium, it is enough to add 1 / 6-1 / 5 of the water, no more than 1-2 times a month, and you should make sure that the hardness and pH values of the water and water in the the aquarium matched.
Cryptocoryne prefers bright lighting, but long-term plant shading is very poorly tolerated. The lighting most often used is a combination of incandescent lamps and fluorescent lamps (type LB), with the required power of fluorescent lamps about 0.4 watts per 1 liter of volume. Incandescent bulbs, used as independent illuminators, should have a power of 1.2 W per 1 liter. It is advisable to use natural lighting. aquarium, but it should be strictly monitored so that there is no excess, since this factor causes the algae to overgrow cryptocorynes, that is poorly tolerated by the plant.
In the presence of bright top light, it is recommended to place small-leaved on the surface of water. floating plants (salvinia, wolfia, azolla). This creates a natural filter. For cryptocorynes, the recommended day length is more than 12 hours.
When growing aponogetonolithic cryptocorynes, special attention is paid to the soil. It should be as saturated as possible with organic nutrients. The quality of the soil can be judged by the growth of cryptocorynes.
If the plant grows well, then the soil is not acidified. When landing cryptocorynes It is recommended to use the soil from the old aquarium in a separate pot or in a new aquarium, or add peat, dried sludge, some charcoal to the soil. Medium and small pebbles, as well as large river sand are best suited as a substrate.
The soil and water of the aquarium should have the same temperature. That is why it is necessary to create a system for not quickly filtering water through the soil or to arrange heating of aquarium water from the bottom. Aquarium installed on the insulating material.
Extremely carefully you need to make minerals in the water, as the excess sodium ions of cryptocoryn does not transfer well. If the plant grows well, it is enough to feed 1-2 times a week with complex mineral fertilizer in minimal doses.
The dose of mineral fertilizers depends on the density of planting. aquarium plants and varies from 0.5 to 1.1 g per 100 liters of water.
In conditions aquarium breeding aponogenic cryptocoryne possible only vegetatively root layering and daughter plants on the rhizome. The breeding process is very slow.
A transplant to a new place of a daughter plant is possible only after how well 3-4 leaves will be formed.
