Echinodorus rubin - AP071
Echinodorus rubin, commonly known as Rubin sword plant or Red Rubin sword, is a species of aquatic plant in the Alismataceae family. It is a cultivated variety or hybrid of the Echinodorus genus, likely derived from Echinodorus barthii. Rubin sword plants are popular in the aquarium hobby due to their striking red to burgundy coloration, which adds a vibrant contrast to the greenery of the underwater landscape.
The most notable feature of Rubin sword plants is their reddish-brown to burgundy colored leaves. The leaves are lance-shaped and elongated, similar to other sword plants, but the deep red hue sets them apart from many other aquatic species. The coloration intensifies under high light and nutrient conditions.
Rubin sword plants can grow to be relatively large, with mature specimens reaching heights of 10 to 16 inches (25 to 40 centimeters) or more. The leaves typically spread to several inches wide.
Like other Echinodorus species, Rubin sword plants develop a robust root system that helps anchor them in the substrate and aids in nutrient absorption.
Rubin sword plants can tolerate a range of water parameters, but they generally prefer slightly acidic to neutral pH (around 6.5-7.5) and water hardness on the softer side.
Rubin sword plants are often used as eye-catching focal points in freshwater aquariums. Their vivid red coloration stands out against the greenery of other aquatic plants, creating a beautiful and visually appealing underwater landscape. The plants provide hiding spots and shelter for fish and contribute to improving water quality by absorbing excess nutrients and providing oxygen through photosynthesis.
When incorporating Rubin sword plants into an aquarium, it's essential to consider their eventual size and growth habit. Provide enough space for the plant to grow, and ensure there is adequate lighting and nutrients to support its development. Regular pruning may be necessary to maintain the desired size and shape of the plant. With proper care, Echinodorus rubin can be a stunning addition to any freshwater aquarium.
Care Tips
- To maintain the vibrant red coloration, Rubin sword plants require moderate to high lighting. Adequate light will support healthy growth and the intense red tones. Additionally, providing a nutrient-rich substrate and regular fertilization will promote optimal growth and development.
- Echinodorus rubin reproduces through runners, which are horizontal stems that grow from the parent plant and produce new plantlets. Once these plantlets develop roots and reach a suitable size, they can be carefully separated from the parent plant and replanted in other areas of the aquarium.
