Alternanthera reineckii, known for its vivid colours and striking appearance, is a favourite among aquarium enthusiasts seeking to add a splash of colour to their aquatic gardens. Originating from South America, this plant is prized for its ability to adapt to various aquarium conditions while providing a stunning visual contrast.

Origin and Natural Habitat

Native to the Amazon basin in South America, Alternanthera reineckii thrives in a range of aquatic environments. Its adaptability to different water conditions in its native habitat translates well to the aquarium setting, making it a versatile choice for aquascapers.

Growth Characteristics

Growth Rate

Alternanthera reineckii exhibits a moderate growth rate, which can be accelerated with optimal lighting and nutrient conditions. Its ability to grow both submerged and emersed makes it a flexible option for different aquarium designs.

Lighting Requirements

This plant thrives under high lighting, which enhances its colouration ranging from pink to deep red. Adequate lighting is crucial for promoting vibrant growth and maintaining the health of the plant.

Water Conditions

Alternanthera reineckii is adaptable to a wide range of water parameters, preferring temperatures between 18°C to 24°C and a pH of 6.0 to 7.5. While it can tolerate various water hardness levels, softer water tends to encourage more robust growth.

Planting and Maintenance

For optimal growth, Alternanthera reineckii should be planted in a nutrient-rich substrate. Regular pruning is recommended to encourage bushier growth and prevent the lower portions of the stems from becoming bare as they stretch towards the light.

Fertilisation and CO2 Supplementation

To achieve the most vibrant coloration and growth, supplementation with CO2 and regular dosing of liquid fertilizers rich in iron and other micronutrients is beneficial. These additions will support the plant’s development and enhance its aesthetic appeal.

Propagation

Propagating Alternanthera reineckii is straightforward; simply cut the top of the stem and replant it in the substrate. The cut stem will quickly root and grow into a new plant, allowing for easy expansion of this colourful species within the aquarium.

Benefits in the Aquarium

Beyond its visual appeal, Alternanthera reineckii can contribute to the aquarium’s ecosystem by providing shelter for small fish and invertebrates. Its dense foliage can also help in absorbing excess nutrients, reducing the likelihood of algae outbreaks.

In conclusion, Alternanthera reineckii is an outstanding choice for aquarists looking to introduce vibrant colours and textures to their planted tanks. With proper care and maintenance, it can become a focal point in any aquarium, captivating onlookers with its lush, colourful growth.
