General Description
Dense-leaved waterweed, or Egeria densa, is a well-known aquatic plant popular in aquariums. Originating from Southeastern Brazil, it has spread globally and can be found in warm water bodies. Belonging to the Hydrocharitaceae family, this fast-growing plant is characterized by its deep green leaves and ability to thrive in both floating and substrate-anchored conditions.
Aquarium Suitability
Egeria densa is highly suitable for aquariums due to its ease of cultivation and widespread availability in commercial markets. It is a very easy plant to care for, making it ideal for beginners. While it does not require CO2 fertilization, additional CO2 can enhance its growth rate. This plant prefers colder temperatures and hard water rich in calcium, but it can tolerate warmer temperatures for short periods.
Demands and Hardiness
With a very fast growth rate, Egeria densa is considered a low-maintenance plant in aquariums. It thrives in medium to high lighting conditions and can tolerate a wide range of water parameters. However, it is important to note that it is not reliably hardy in Central Europe, so caution is advised in colder regions.
Aquascaping & Usage
While Egeria densa can be challenging to incorporate into decorative aquascapes due to its rapid growth and temperature sensitivity, it makes an excellent background plant if trimmed regularly. The plant's deep green foliage creates a beautiful contrast with other aquarium plants, adding visual interest to the tank.
Propagation
Propagation of Egeria densa is simple and can be achieved through fragmentation or cuttings. Lateral shoots are common in this plant, especially when kept as a floater. By cutting off a part of the plant and replanting it in the substrate, new growth can be easily encouraged.
Habitat and Distribution
In its native habitats of Brazil, Argentina, and Uruguay, Egeria densa prefers deep, slow-flowing, or stagnant water. However, it has been introduced to temperate-tropical regions worldwide through the aquarium trade. The plant's adaptability and ability to thrive in various environmental conditions have contributed to its widespread distribution.
