Lagenander ovoid (Lagenandra ovata) – aquarium plant families Aronnik or Araid (Araceae).
Homeland langenandra ovoid considered the island of Sri Lanka. In nature plant grows in galyto-clay soil along streams and rivers.
Aquarists rarely contain this plant.
Lagenander ovoid refers to marsh plants. Its leaves are extended upwards, up to 40 cm long and up to 15 cm wide, with a fleshy petiole reaching up to half a meter in length. The underwater part reaches a half-meter height, but its growth is slowed down.
The surface at eight weeks is covered with slightly wrapped and curved flowers that have a silver color on the outside and purple-red on the inside. The color of the plant is bright green.
Have langenandra ovoid well-developed root system, which is a creeping cord roots up to 8 mm in diameter.
For content langenandra ovoid will require a large and spacious aquarium. It will feel comfortable in water with a temperature of 24-28 ° C, hardness up to 18 ° and slightly acid or neutral reaction.
The plant tolerates very low water temperature. Needs regular substitution of up to a quarter of the total water in aquarium.
At the same time, it is necessary to take into account the parameters of the added water – they should not differ from those of old water. Recommended to support aquarium in a pure state and try to avoid the appearance of turbidity, which is extremely negative for the development langenandra ovoid (until her death). Planted in the background or middle plan aquarium.
Lighting for content this plant should be moderate. Can be used as natural. lighting, and artificially created. It is necessary to protect the plant from direct sunlight.
For this fit floating on the surface of the plant, which will create the necessary shading. In the second case, both fluorescent lamps and incandescent lamps can be used as light sources. Power lights selected individually.
With too much light, algae may develop on the leaves. lagengenra. For content plants in aquarium the soil should be well silted and contain nutrients.
When landing in the ground under the roots of the plant spread charcoal and clay. It does not need additional feeding with the help of substances added to water, since it receives everything that is needed through the root system.
Contain lagengenru ovoid in the paludarium more rationally than in aquarium, as in a marshy ground and a humid atmosphere, plant growth parameters are optimal. The content parameters are as follows: air and water temperature within 26-30 ° C, bright light, nutritious soil.
These conditions are favorable for plant reproduction.
Lagenander ovoid multiplies by separating from the rhizome daughter plants with leaf buds, which are formed only on the rhizome, and then rooted in the aquarium soil. After that, the plant is sick for some time, its leaves become shallow, then everything returns to normal.
The plant blooms in the paludarium, but it cannot be obtained in this way.
