Care Guide
To successfully cultivate Giant Red Rotala, attention to specific environmental conditions is crucial. This plant thrives in a well-lit aquarium, ideally with at least 2-3 watts per liter of light. High-quality fixtures, such as LED or T5 fluorescent lights, should be utilized to encourage vibrant coloration and dense growth.
Additionally, maintaining stable water parameters is essential. The optimal temperature range for Rotala macrandra is between 22°C and 28°C (72°F to 82°F) with a pH level between 6.0 and 7.5. Regular water changes are recommended to prevent the buildup of harmful substances and to ensure nutrient levels remain balanced.
For best results, it is advisable to trim the plant regularly to promote bushier growth and to prevent overshadowing of lower leaves, maintaining both health and aesthetic appeal.
