Lighting & CO2: For optimal growth, the plant requires intense lighting and constant CO2 supply to induce and maintain the vivid red colors and promote compact growth. Intense light promotes shorter internodes and the development of more saturated colors, while the CO2 supply ensures stable photosynthesis, preventing plant tissue decay. In the absence of these elements, the plant will tend to stretch excessively towards the light, losing its lower leaves and exhibiting weak, stunted growth.
Nutrition & Substrate: Nutrition must be managed by providing a fertile substrate and liquid fertilization rich in chelated iron and micronutrients to support red pigmentation. A fertile substrate or the use of root tabs near the root system significantly accelerates growth, while
Water Chemistry: This species prefers temperature between 15 and 30 °C, pH between 6.0 and 7.5, and a carbonate hardness (KH) between 2 and 12. Regular water changes are recommended to maintain stable parameters and low levels of pollutants such as nitrates and phosphates. Good mechanical and biological filtration will ensure an environment free of suspended particles, which could settle on the leaves and limit photosynthesis.
Space Management & Placement: The ideal placement is the midground of the aquarium as a color accent, placing the stems close together to form a dense bush. As a plant that can expand laterally or vertically, it is important to carefully calculate distances from neighboring species to avoid mutual shading. Proper water circulation among the foliage also prevents the formation of stagnant zones susceptible to bacterial infections.
Pruning: Maintenance is carried out by shortening the top stems to encourage the release of new low axillary shoots and maintain a compact bush. Periodically removing older or damaged leaves at the base stimulates the plant to focus energy on new growth. Using sterile, very sharp tools is essential to avoid crushing stem tissues, which could lead to necrosis or fungal infections.
Risks & Diseases: The main risks include loss of red color and leaf melting if light is low, and vulnerability to filamentous algae. Under conditions of poor water movement or nutrient imbalance, the leaves can be colonized by filamentous or green spot algae. In cases of severe stress, the stems can rot from the inside; if this occurs, damaged parts must be removed immediately to prevent infecting the entire plant.
