It is a stem plant with vibrant green foliage that adds a lush and attractive appearance to freshwater aquariums. Here are some care guidelines to help you successfully cultivate and maintain Rotala rotundifolia 'Green' in your aquarium:
Water Parameters:
Temperature: Rotala rotundifolia 'Green' thrives in tropical temperatures ranging from 72-82°F (22-28°C).
pH: It prefers slightly acidic to neutral water with a pH range of 6.0-7.5.
Hardness: Soft to moderately hard water with a dGH of 2-10 is ideal for this plant.
Lighting: Moderate to high lighting of at least 2-3 watts per gallon is recommended to promote healthy growth and intense coloration.
Substrate:
Rotala rotundifolia 'Green' can be planted in a variety of substrates, including gravel, sand, or aquatic plant-specific substrate. However, a nutrient-rich substrate, supplemented with root tabs, will promote faster growth and stronger root development.
Fertilization:
Provide regular fertilization to ensure optimal growth. You can use a complete liquid fertilizer or add root tabs to the substrate to provide essential nutrients like nitrogen, phosphorus, and potassium. CO2 injection is not mandatory but can enhance growth and coloration.
Propagation:
Rotala rotundifolia 'Green' is an easy plant to propagate through stem cuttings. Simply trim the tops of healthy stems and replant them in the substrate. New shoots will quickly emerge from the cuttings and form new plants.
Maintenance:
Regular pruning is necessary to maintain a bushy and compact growth habit. Trim the tops of the stems to encourage lateral branching and prevent the plant from becoming too tall and sparse.
Keep an eye out for signs of nutrient deficiencies such as yellowing leaves or stunted growth, and adjust fertilization accordingly.
Remove any dead or decaying leaves promptly to prevent them from rotting and causing water quality issues.
Aquarium Placement:
Rotala rotundifolia 'Green' is best placed in the midground or background of the aquarium, where it can serve as a focal point or backdrop for other aquatic plants or fish.
Tankmates:
Rotala rotundifolia 'Green' is compatible with a wide range of aquarium fish and invertebrates. Avoid keeping it with herbivorous fish or snails that may graze on the foliage.
Potential Challenges:
Rotala rotundifolia 'Green' may experience melting or shedding of lower leaves when transitioning to a new aquarium or adjusting to different water conditions. This is normal and can be remedied with proper water parameters and nutrient supplementation.
Algae growth on the leaves is a common challenge. Ensure that lighting and nutrient levels are balanced, and practice good aquarium maintenance to prevent excessive algae growth.
By following these care guidelines, you can successfully cultivate and enjoy the beauty of Rotala rotundifolia 'Green' in your aquarium. Remember to monitor water parameters, provide adequate lighting and nutrients, and perform regular maintenance to keep this plant healthy and thriving.
