an In-depth Look

Updated: December 23, 2022

Aquarium plants are not just for decoration; they play an essential role in maintaining a healthy aquatic environment. Cardinalis aquarium plants are particularly popular among aquarists due to their bright red coloration and ease of care. However, before adding cardinalis aquarium plants to your tank, it is essential to understand their roots and stems.

Cardinalis Aquarium Plant Roots

The roots of cardinalis aquarium plants are an essential aspect of their growth and survival. The roots serve several functions, including anchoring the plant in the substrate, absorbing water and nutrients from the water column, and storing carbohydrates.

Cardinalis aquarium plants have a fibrous root system that extends deep into the substrate. The roots are thin and delicate, making them susceptible to damage during planting or maintenance. It is essential to handle the plants gently and avoid disturbing the substrate around the roots.

Cardinalis aquarium plants require a nutrient-rich substrate to thrive. A high-quality substrate should be rich in essential minerals like iron, potassium, and magnesium. A nutrient-rich substrate promotes healthy root development and encourages the growth of strong stems.

Cardinalis Aquarium Plant Stems

The stems of cardinalis aquarium plants are another critical aspect of their growth and development. The stems serve as a support structure for the leaves and flowers and transport water and nutrients throughout the plant.

Cardinalis aquarium plants have a thin stem that can grow up to 12 inches tall. The stem is covered in small, green leaves that grow in pairs along its length. The leaves are lance-shaped and have a slight curve, giving them a unique appearance.

Proper lighting is crucial for the growth of cardinalis aquarium plant stems. Insufficient light can cause the stems to become weak and spindly, while too much light can cause them to become stunted or damaged. A balance between light intensity and duration is necessary to promote healthy growth.

Cardinalis Aquarium Plant Care

Proper care is essential for the health and longevity of cardinalis aquarium plants. Here are some tips for caring for these plants:

  • Lighting: Cardinalis aquarium plants require moderate to high lighting to thrive. LED lights are an excellent choice for providing the right amount of light intensity and duration.
  • Substrate: A nutrient-rich substrate is vital for the growth of cardinalis aquarium plants. Use a substrate that is specifically designed for aquatic plants and contains essential minerals like iron, potassium, and magnesium.
  • Fertilizer: Regular fertilization is necessary to provide cardinalis aquarium plants with the nutrients they need to thrive. Use a liquid fertilizer that is specifically formulated for aquatic plants, and follow the manufacturer’s instructions.
  • Water Parameters: Cardinalis aquarium plants prefer slightly acidic water with a pH between 6.0-7.5. They also require soft to moderately hard water with a hardness level between 4-8 dKH.
  • Maintenance: Regular maintenance is necessary to keep cardinalis aquarium plants healthy. Trim dead or damaged leaves and stems, remove any debris from the substrate, and perform water changes as needed.


Can I plant cardinalis aquarium plants in gravel?

While it is possible to plant cardinalis aquarium plants in gravel, they will not thrive as well as they would in a nutrient-rich substrate.

What fish are compatible with cardinalis aquarium plants?

Cardinalis aquarium plants are compatible with most fish species. However, avoid keeping them with fish that are known to be aggressive or that may uproot the plants.

How often should I fertilize my cardinalis aquarium plants?

It is recommended to fertilize cardinalis aquarium plants once a week or as directed by the manufacturer of the fertilizer.

Can I grow cardinalis aquarium plants without CO2 injection?

Yes, cardinalis aquarium plants can grow without CO2 injection. However, they may not grow as quickly or as vibrantly as they would with CO2 injection.

In conclusion, cardinalis aquarium plants are a beautiful and beneficial addition to any aquarium. Understanding their roots and stems is essential for providing them with the proper care they need to thrive. With proper care, cardinalis aquarium plants can provide many years of enjoyment and a healthy aquatic environment for your fish.
