About This Species
The Cardinal Plant is a beautiful and unique addition to any freshwater tank, known for its vibrant green leaves that often have a striking purple or reddish underside. This contrast makes it a standout choice for adding a splash of color to the middle section of your aquarium. While not the easiest plant for a first-timer, it's a rewarding challenge for those looking to expand their skills. It grows upwards in a single, distinct stalk, making it look very neat and organized. To keep it happy, you'll need a good light and a nutrient-rich base like aquarium soil or gravel enriched with root-tabs, as it absorbs many nutrients through its roots. It grows at a slow to moderate pace, so you won't need to trim it constantly. If you want to create more Cardinal Plants, you can simply snip the top half of a healthy stalk and replant it into the substrate, where it will grow new roots. Its slower growth means you should watch out for algae growing on its leaves, which can be a sign that there's too much light or a nutrient imbalance in the water.
