South America is the homeland. The plant is widespread throughout Earth’s tropical regions.
It is a rosette of original-shaped, glossy, bright green leaves with an air chamber at the base. It helps the plant to stay afloat. It gets its name from a lovely inflorescence that has a potent, pleasant scent. It grows incredibly quickly in the wild, frequently getting in the way of shipping, even on big rivers.
The plant is very particular about the conditions it must be kept in an aquarium. Fish fry find refuge among its highly developed roots. Eichhornia is incredibly helpful in an aquarium because of its capacity to extract nitrogen compounds and other byproducts of fish metabolism from water. It has been reported that this plant can even absorb phenolic compounds. Therefore, the best filter can be replaced by Eichhornia, which has the capacity to absorb and perfectly filter water from suspended particles.
For Eichhornia, the water temperature needs to be sufficiently high. 26 to 28 °C (up to 30 °C) is a very warm aquarium necessary for successful growth. There should be a tightly closed, humid air chamber in the aquarium that is at least 20 cm high. Dry air and drafts are completely intolerable to the plant. The water should react slightly acidic and be soft. Hardness < 6 °C; ideal pH range is 6.8–7.8. The air and water temperatures must be at least 30 to 32 °C for eichhornia to bloom.
Eichhornia needs lighting that is extremely bright. The LB type of fluorescent lamps can be used to create lighting conditions that are satisfactory. The following ratio can be used to determine the lighting’s power: 3.2–3.5 W per square meter of the water’s surface. The lamps need to be raised by 25 to 30 centimeters above the water.
Incandescent lights are not a good choice for lighting. They burn leaves because they are situated at the same distance from the plant. You must greatly increase the lamps’ power in order to move them farther. Lights on 12–14 hours.
It’s easy to keep Eichhornia in direct sunlight during the summer. The plant slows down its growth in the fall as natural light levels drop, and in unfavorable conditions, it rots and dies. You can keep the plant through the winter by keeping the water at a high temperature and bright artificial lighting.
However, in winter it is difficult to maintain the conditions in the room necessary for the successful growth of Eichhornia. Therefore, it is better to use another, long-known method of preserving Eichhornia. A well-developed plant is placed in a ring float (it is best to make it from foam) so that the roots from the very base are immersed in water, and the leaves, located on the float, do not touch the water. Otherwise, the leaf cuttings begin to rot. Under the plant at a depth of about 5 cm, you need to put a pot with silted soil so that the roots can grow into the soil. In such conditions, at a temperature of 24 – 26 ° C and normal aquarium lighting, Eichhornia successfully overwinters. With the onset of spring, it is necessary to increase the lighting and raise the water temperature.
Eichhornia produces daughter plants at the tips of its lateral shoots, making reproduction extremely simple. Once the young plants have three or four leaves, they can be divided from the parent plant. Full-fledged seeds cannot be obtained in an aquarium.

Aquarium enthusiasts find Eichhornia crassipes, also referred to as water hyacinth, to be an intriguing plant because of its remarkable appearance and quick growth. By absorbing excess nutrients, this floating aquatic plant not only gives any aquarium a lush, vibrant green look, but it also helps to improve the quality of the water. To keep it from overwhelming the tank, it’s crucial to control its explosive growth. You can keep an aquarium environment that is both aesthetically pleasing and healthy by being aware of its requirements and advantages.
