Description

Echinodorus rubin is one of the classic large red sword plants, producing broad, deeply coloured leaves in rich ruby-red to dark maroon that retain their intensity even as the plant matures. It is a vigorous grower capable of reaching 40–50 cm in height, making it a commanding background specimen in any spacious planted aquarium.

Care is straightforward. Medium light and no CO2 injection are all it needs to thrive, though its size means it benefits greatly from a nutrient-rich substrate or regular root tabs to fuel the extensive root system. Good light and iron in the substrate help sustain the deep red pigmentation on both new and mature leaves.

Supplied as an established potted plant, Echinodorus rubin suits aquariums of 200 litres or more. Its bold colouration and large stature make it one of the most visually impactful background plants available, providing an immediate and lasting focal point in the planted aquarium.

Common Questions

How intense is the red on Echinodorus rubin?

Very intense. Leaves develop a deep ruby to maroon red that holds well even on mature leaves, unlike some cultivars where older leaves turn green.

Does it need CO2?

No. Despite its large size, it grows without CO2. Root tabs and a nutritious substrate are more important than CO2 for this species.

How large does it get?

It can reach 40–50 cm in height in a mature aquarium. It is best suited to aquariums of 200 litres or more.

How do I maintain the deep colour?

Good medium light and iron-rich fertiliser or substrate are key. Ensure root tabs are replenished every few months to keep nutrient levels up.

Is it related to Echinodorus rubin narrow leaf?

Yes, rubin narrow leaf is a cultivar of the same variety with slightly narrower leaves. Both share the same deep ruby colouration and easy care requirements.
