Image is for reference only Size: As indicated by the "XXL" designation, Dennerle Echinodorus argentinensis XXL is a larger-sized plant compared to regular specimens. The specific dimensions or measurements may vary, but it is generally intended to provide a more substantial presence in the aquarium.

Appearance: Echinodorus argentinensis has broad, elongated leaves that grow in a rosette form. The leaves are typically a vibrant green color and can reach a significant size, especially in the case of XXL specimens. The plant's size and lush foliage can create a striking focal point in the aquarium.

Growth: Echinodorus argentinensis is known to be a relatively fast-growing species compared to other Echinodorus varieties. Its growth rate can be moderate to fast under favorable conditions, and it may produce new leaves regularly, adding to its voluminous appearance.

Lighting and CO2 Requirements: Echinodorus argentinensis typically thrives in moderate to high lighting conditions. Adequate lighting is necessary to support the plant's photosynthesis and promote healthy growth. While this plant can benefit from carbon dioxide (CO2) supplementation, it can also grow well without it, making it suitable for both low-tech and high-tech aquarium setups.

Water Parameters: Echinodorus argentinensis can adapt to a range of water parameters, although it generally prefers the following:

• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5
• Hardness: Soft to moderately hard water (2-15 dKH)

Placement and Propagation: Echinodorus argentinensis can be used as a background plant or as a centerpiece in larger aquariums. It should be planted in the substrate, making sure to provide enough space for its sizeable rosette to spread out. Propagation can be achieved by dividing the plant at the root level and replanting the separate sections.
