Origin and Characteristics
Alternanthera belongs to the Amaranthaceae family and originates from the tropical regions of South America. Different species of this plant, each with unique colors and forms, meet diverse needs in aquascaping. Its leaves often appear in shades of red, purple, pink, or dark green, and their intensity changes depending on light levels. This ability to shift colors makes Alternanthera a powerful visual element in aquarium design.
Alternanthera Reineckii Green
This species is popular and resilient, with glossy green leaves and a compact form that brings a natural, calming look to planted aquariums. Unlike other colorful varieties, Reineckii Green enhances freshness and balance with its pure green tone. It thrives under medium to high light and grows faster with CO₂ injection and regular fertilization. Its tolerance to water quality fluctuations makes it suitable for beginners.

Beyond aesthetics, it contributes to oxygen production, nutrient absorption, and provides shelter for fish.
Alternanthera Betzickiana Green
This variety features oval, delicate, and symmetrical leaves that shine naturally under good lighting. Unlike red or pink species, Betzickiana Green conveys freshness and tranquility, as if a piece of forest has flowed into the water.
