The Brazilian Red Hot Alternanthera, scientifically known as Alternanthera reineckii 'Mini' or sometimes just Alternanthera reineckii 'Red', is a captivating aquatic plant prized for its striking crimson foliage. Its intense color and relatively easy care make it a popular choice for both experienced and beginner aquascapers, and it's even finding its place in terrestrial gardens as well. This comprehensive guide delves into everything you need to know about this vibrant plant, from its care requirements to its potential uses.
What Makes the Brazilian Red Hot Alternanthera Unique?
This stunning plant boasts a rich, deep red coloration that intensifies under strong light. Unlike some other red plants, the Brazilian Red Hot Alternanthera maintains its vibrant hue even in slightly less demanding conditions, although optimal light is key to maximizing its color. Its compact size, typically growing to only a few inches tall, makes it ideal for midground or foreground planting in aquariums. The small, ovate leaves are densely packed along the stem, creating a full and lush appearance. It also exhibits a relatively slow growth rate compared to other aquatic plants, making it easier to manage in a planted tank.
How to Care for Your Brazilian Red Hot Alternanthera
Light Requirements:
- High Light: While it can tolerate moderate lighting, high-intensity lighting is essential for maintaining its intense red color. Aim for at least 2-4 watts per gallon of aquarium space, or supplemental LED lighting if your tank doesn't provide enough.
Water Parameters:
- Temperature: 72-82°F (22-28°C) is ideal.
- pH: A slightly acidic to neutral pH (6.0-7.5) is best.
- Hardness: Moderate hardness is preferred.
Nutrient Requirements:
- Fertilization: Regular fertilization is crucial. A balanced liquid fertilizer containing macro and micronutrients is recommended. Consider root tabs for added nutrients. Watch for signs of nutrient deficiency, like pale leaves or stunted growth.
CO2 Injection:
- Carbon Dioxide: While not strictly necessary, adding CO2 to the aquarium will significantly enhance the plant's growth and color intensity.
Pruning and Propagation:
- Pruning: Regular pruning helps maintain its shape and encourages bushier growth. Simply trim the top few inches of the stems to promote branching.
- Propagation: Propagation is easy! Cuttings from pruned stems readily root and can be planted directly into the substrate.
Can You Grow Brazilian Red Hot Alternanthera in a Terrestrial Setting?

It prefers well-draining soil rich in organic matter and partial shade. Think of it as a vibrant addition to a rain garden or a moist area of your landscape.
