Care Tips: Gymnocoronis spilanthoides, also known as "Swampweed," is a fast-growing aquatic plant that is great for filling larger aquariums with its vibrant, lush green foliage. It thrives under medium to high lighting, which helps produce the best leaf coloration and compact growth. It prefers a nutrient-rich substrate, and regular fertilization, especially with iron and micronutrients, helps it grow well. CO₂ supplementation is beneficial for faster growth and better overall health, but it can still thrive in a low-tech setup. Gymnocoronis spilanthoides grows quickly, so trimming may be needed regularly to maintain its size and shape. It works well as a midground or background plant in aquascapes and adds a lot of green coverage to a tank. This plant is adaptable to a range of water conditions, but it performs best with stable water parameters and slightly acidic to neutral pH (6.0–7.5). It's an excellent plant for those looking for an easy-to-care-for, fast-growing, and attractive addition to their aquarium.
