Care sheet for Ludwigia peruensis, commonly known as 'Diamond Ludwigia,' which is a beautiful and vibrant aquatic plant known for its striking red coloration.
Common Name: Ludwigia peruensis (Diamond Ludwigia?)
 
Water Requirements: Ludwigia peruensis prefers slightly acidic to slightly alkaline water with a pH range of 6.0 to 7.5. It can tolerate a wide range of water hardness levels, but softer water is generally preferred. The temperature should be kept between 68 to 82 degrees Fahrenheit (20 to 28 degrees Celsius). Stable water parameters are important for optimal growth.
Lighting Requirements: High lighting is recommended for Ludwigia peruensis to promote intense red coloration. Provide a good-quality aquarium light with a color temperature of 6500K to 7500K and high intensity to ensure sufficient light penetration to the lower parts of the plant. Consider using a full spectrum LED or a high output T5/T8 fluorescent light for best results.
Substrate and CO2: Ludwigia peruensis can be planted in a variety of substrates, including gravel, sand, or aqua soil. It can grow in nutrient-poor substrates, but adding a nutrient-rich substrate or using root tabs can promote faster and healthier growth. CO2 (carbon dioxide) supplementation is not mandatory, but it can greatly enhance the plant's growth, coloration, and overall health, especially in high light setups.
Fertilization: Regular fertilization is crucial for the healthy growth and vibrant coloration of Ludwigia peruensis. You can use a liquid or substrate fertilizer formulated for aquatic plants, and follow the manufacturer's instructions for dosing. Providing essential nutrients, such as nitrogen, phosphorus, and potassium, is important for promoting healthy growth and enhancing the plant's red coloration.
Propagation: Ludwigia peruensis can be propagated through stem cuttings. Simply trim the top 4-6 inches of healthy stems and replant them in the substrate. New roots will develop from the cuttings, and the plant will continue to grow. Regular pruning will help maintain its shape and promote bushy growth.
Maintenance: Regular maintenance is necessary to keep Ludwigia peruensis healthy and vibrant. Remove any dead or decaying leaves promptly to prevent them from rotting and causing water quality issues. Prune the plant regularly to control its height and promote bushy growth. Monitoring and maintaining stable water parameters, including temperature, pH, and nutrient levels, is crucial for optimal growth and coloration.
Compatibility: Ludwigia peruensis is generally peaceful and can be kept with a variety of fish and other aquatic species. However, it can be a target for herbivorous fish that may nip at the leaves, so choose tankmates carefully. It is also important to provide enough space for the plant to grow and avoid overcrowding, as it may shade out other plants if allowed to grow too densely.
In conclusion, Ludwigia peruensis is a stunning aquatic plant that can add a burst of vibrant red color to your aquarium. With high lighting, regular fertilization, and proper maintenance, you can enjoy healthy growth and intense coloration from this beautiful plant in your freshwater aquarium.
