Atonogeton wavy (Aponogeton stachysporus, undulatus), or as it is called, Atonogeton viviparous – aquarium plant, belonging to genus Atonogeton (Aponogeton), family Aponogontonovye (Aponogetonaceae) .
Homeland Atonogeton wavy is india. It is also believed to be common in Burma, Bangladesh, Thailand, Indonesia, and Malaysia.
Habitat Atonogeton viviparous are ditches, ponds, swamps.
Rhizomes Atonogeton viviparous tuberiform, translucent leaves, with a pattern on them and a narrowed top, have a length of 25 cm and 4 cm wide. The height of the bush in favorable conditions can be 70cm.
Atonogeton wavy known among aquarists as an unpretentious aquarium plant and has excellent decorative qualities. The leaves have a light green color and a beautiful chess pattern.
Place Atonogeton wavy necessary in the background aquarium. In small aquariums the plant is stunted even in favorable conditions, but at the same time it retains its attractiveness and originality. Grows evenly throughout the year, but looks best in summer and autumn.
In nature, it blooms in late summer, and in aquarium blooms rarely. Needs a bright illuminated.
For lighting you can use incandescent and fluorescent lamps such as LB. Lighting power should be as follows: 0.4-0.5 W for fluorescent lamps and 1.2-1.5 W for incandescent lamps.
Prolonged shading by the plant is poorly tolerated. Natural light will be useful to him.
The temperature of the water should be between 22-28 ° C. In cooler water Aponogeton slows its growth and can shed its leaves. At the same time in the ground tuber is preserved, and upon the occurrence of favorable conditions gives new leaves.
Water should be soft and neutral or weakly acidic. Optimal conditions content the water hardness is 40 and the pH is less than 7. With a water hardness greater than 80, the plant grows slowly and does not reach a large size.
The soil should be nutritious and with a moderate amount of sludge. If the soil contains a lot of sludge, then the tender rhizome of the plant rots. The substrate should consist of coarse sand and small pebbles.
If the substrate consists of larger particles, then the roots will develop worse. The soil layer should be at least 3 cm, and for adult plants – 5 cm.
Breeding Atonogeton viviparous occurs vegetatively. A parent plant can form seven children in one growing season.
Arrows are formed from the mother plant, which stretch to the surface. Then a nodule forms at the end of the arrow, from which the leaves of the young plant appear. Over time, the knot grow in size and turns into a tuber.
Plant with a tuber can be separated and planted in the ground aquarium. Roots grow quickly.
If a young plant is not separated, then when the tuber grows in size up to 5 mm, the arrow will rot and the plant will float freely near the surface of the water and throw out more and more young leaves. Old leaves die in this case. As a result plant sinking under the weight of its tuber and sinks to the ground, where it forms the root system and a large rosette of leaves.
Its name “Viviparous” Atonogeton wavy received thanks to its reproduction characteristics.
