General Description
Rotala mexicana, also known as Rotala pusilla, is a relatively new stem plant in the aquarium hobby, originating from tropical and subtropical regions such as South America, Western Africa, Australia, and Japan. This species is highly variable, as indicated by its multiple synonyms, with the South-American variety R. mexicana 'Araguaia' being one of the most popular choices. Featuring reddish stems and pointy yellowish-green leaves, R. mexicana is a fast-growing plant that can thrive if provided with strong light, ample CO2, and a rich supply of macro- and micronutrients.
Aquarium Suitability
Rotala mexicana is deemed suitable for aquariums, especially for hobbyists with medium-level experience due to its specific care requirements. The plant grows fast and lush under proper conditions, making it an attractive choice for background or midground planting, and even for nano tanks. It is essential to maintain high light levels, proper CO2 levels (25-40mg/l), and nutrient-rich water to ensure the optimal growth of R. mexicana.
Demands and Hardiness
According to the provided information, Rotala mexicana has medium care demands and needs favorable conditions to thrive. It requires high light levels, a temperature range of 22-28°C, and a pH range of 4.5-7. Additionally, adequate levels of nitrate (10-50mg/l), iron (0.01-0.5mg/l), and phosphate (0.1-3mg/l) are essential for its healthy growth. Although specific in its requirements, when well-maintained, this plant can grow rapidly and be a beautiful addition to the aquarium.
Aquascaping & Usage
Rotala mexicana can be effectively used in aquascaping to create a lush and vibrant background or midground. Its branching nature allows for easy propagation through cuttings, enabling aquarists to achieve a dense and hedgelike planting style if trimmed regularly. The striking coloration of the plant's stems and leaves makes it a visually appealing choice for aquascaping, adding a pop of color to any aquarium setup.
Propagation
Propagation of Rotala mexicana is typically done through cuttings. Given the plant's fast growth rate and readiness to branch, propagating new specimens from clippings is relatively straightforward. By providing suitable conditions and regular maintenance, aquarists can encourage the growth and spread of R. mexicana within the aquarium.
Habitat and Distribution
Rotala mexicana is native to various regions worldwide, including South America, Western Africa, Australia, and Japan. The plant thrives in tropical and subtropical climates, where it can be found in aquatic environments. Different varieties of R. mexicana, such as the popular 'Araguaia' variant, exhibit slight differences in growth patterns and coloration, adding to the plant's overall variability and appeal.
