General Description
Hassler's Alternanthera, scientifically known as Alternanthera aquatica, is a unique aquatic plant belonging to the Amaranthaceae family. It is native to Brazil, Paraguay, and Bolivia, commonly found in riversides, lakeshores, and swampy areas. This floating plant exhibits a distinctive growth pattern, with long shoots that can extend several meters above the waterline. The internodes of Alternanthera aquatica are air-filled, giving them a swollen appearance, adapted for their life as a floating species.
Aquarium Suitability
Hassler's Alternanthera is occasionally available commercially and is considered suitable for aquariums, given its medium difficulty level in care requirements. It is a fast-growing plant that can thrive in medium to high light conditions within a temperature range of 18-30°C. Its growth habit as a stem or free-floating plant makes it an interesting addition to aquascapes, particularly ideal for surface coverage in tanks.
Demands and Hardiness
The aquarium setup for Alternanthera aquatica should include a pH range of 5-8, carbon dioxide levels between 0-40mg/l, and a nitrate concentration of 10-50mg/l. It thrives in water with a carbonate hardness of 0-21 and requires moderate levels of iron (0.01-0.5mg/l), phosphate (0.1-3mg/l), and potassium (5-30mg/l). While it is suitable for aquariums, this plant is unsuitable for outdoor use in colder climates due to its winter hardiness limitations.
Aquascaping & Usage
Alternanthera aquatica can be utilized in aquascaping layouts to create a visually appealing water surface. Its vibrant medium green coloration adds a unique aesthetic element to aquariums. This plant serves as a natural habitat and shelter for other floating species like Limnobium laevigatum, Phyllanthus fluitans, Eichhornia crassipes, and Ludwigia helminthorrhiza, providing a well-protected environment for aquatic organisms.
Propagation
Propagation of Hassler's Alternanthera primarily occurs through cuttings. By snipping and replanting the stems, aquarists can encourage the growth and expansion of this plant in the aquarium environment, maintaining its lush appearance and enhancing the overall aquatic landscape.
Habitat and Distribution
In its natural habitat, Alternanthera aquatica thrives along the water's edge, taking root in muddy substrates rich in nutrients. Its distribution spans across the regions of Brazil, Bolivia, and Paraguay, where it contributes to the biodiversity of aquatic ecosystems, particularly in areas near rivers, lakes, and wetlands.
