Echinodorus 'Joyo Red' (Joyo Red Star)

Echinodorus 'Joyo Red' is a striking hybrid sword plant valued for its deep red foliage and relatively compact size. It is a popular choice for aquariums because it provides a strong red focal point without growing as large as many traditional Amazon sword plants.

Appearance

• Long, sword-shaped leaves.

• New leaves emerge bright ruby red.

• Mature leaves may develop shades of red, bronze, and green.

• Some plants display pale veins that contrast beautifully with the red leaf surface.

Size

• Height: 20–30 cm (8–12 inches).

• Width: 20–30 cm.

• Forms a rosette with leaves growing from a central crown.

Difficulty

Easy to moderate.

It is generally hardy and suitable for aquarists with some basic plant-keeping experience.

Lighting

• Medium to high lighting is recommended.

• Stronger lighting enhances red coloration.

• Low light may cause the plant to become greener.

CO₂ Requirements

• Soft to moderately hard water

Placement

Best used as:

Growth Rate

• Moderate growth.

• Faster growth with strong lighting, CO₂, and nutrient-rich substrate.

Propagation

• Produces plantlets on flower stalks.

• Daughter plants can be separated once they develop roots.

• Large mature plants may occasionally be divided.

Common Problems

Leaves turning green

• Insufficient light.

• Iron deficiency.

Slow growth

• Poor substrate nutrition.

• Lack of root fertilization.

Leaf melt after planting

• Common when transitioning from emersed to submerged growth.

• New underwater leaves usually replace the old ones within a few weeks.

Compatible Tankmates
