General Description
Echinodorus opacus Rataj, commonly known as the Brazilian Sword Plant, is an aquatic plant belonging to the family Alismataceae. This plant is native to southeastern Brazil, specifically found in the regions of Paraná and Santa Catarina. It is categorized under seed plants and is classified under the order Alismatales. The plant typically grows in a rosette form with slow growth, making it an intriguing addition to aquariums.
Aquarium Suitability
Considered suitable for aquariums, the Brazilian Sword Plant is categorized as a midground plant that thrives in water conditions with medium to high light intensity. With a temperature range of 18-24°C (64-75°F) and a tolerance range of 8-27°C (46-81°F), this plant can adapt to varying temperatures within aquarium settings. It demands iron levels of 0.01-0.5 mg/l, nitrate levels of 10-50 mg/l, pH levels ranging from 5 to 7, phosphate levels of 0.1-3 mg/l, and potassium levels of 5-30 mg/l for optimal growth. Its winter hardiness remains unknown.
Demands and Hardiness
In terms of propagation, the Brazilian Sword Plant can be spread through proliferating inflorescences, rhizome division, splitting, and cutting off daughter plants. Although this aquatic plant may not be readily available commercially, it can be cultivated and propagated by aquarists interested in its unique features and care requirements.
Aquascaping & Usage
With its rosette growth pattern and midground designation, the Brazilian Sword Plant offers aquarists the opportunity to create visually appealing aquatic landscapes. Its slow growth rate enables aquascapers to design intricate layouts while providing suitable habitats for fish and other aquatic species.
Habitat and Distribution
In its natural habitat in Brazil, Echinodorus opacus Rataj is commonly found in the water bodies of Paraná and Santa Catarina. Thriving in freshwater environments, this plant contributes to the biodiversity of these regions, enriching aquatic ecosystems with its unique characteristics and adaptability to varying water conditions.
