Origin

Eleocharis vivipara is native to the southeastern United States, where it grows in shallow waters, wetlands, and marshy environments.

Ideal Placement in an Aquarium

This plant is best used in the background to midground of aquariums. Its long, fine leaves create a grassy, natural look, especially when planted in groups.

Lighting Requirements

Bright lighting is essential to maintain compact growth and vibrant green coloration. In low light, the plant may become leggy or fail to thrive.

Water Conditions

• pH range: 6.5 – 7.2
• Water hardness (dGH): 4 – 12°N (71 – 214 ppm)
• Temperature: 22 – 26 °C (72 – 79 °F)

Growth and Size

This species grows at a moderate pace and can reach a height of 20–25 cm (8–10 inches) when fully submerged. Regular trimming helps keep it neat and prevents excessive shading of smaller plants.

Propagation

Eleocharis vivipara reproduces mainly through runners (stolons) that spread across the substrate and produce new shoots. It is also known for occasional viviparous propagation, where new plantlets form directly on older leaves, especially in emersed or semi-submerged growth.

Substrate and Fertilization

Use a fine gravel or nutrient-rich substrate to support healthy root development. Supplement with root tabs or liquid fertilizers if needed, especially in low-tech setups.

Difficulty

Easy to moderate. It adapts well to a range of water conditions and doesn’t require CO₂ injection, though added CO₂ and nutrients enhance growth and appearance.

Short Description

Eleocharis vivipara is a graceful grass-like plant ideal for aquascaping. Its fine, arching stems give tanks a wild, natural look while offering hiding spaces for fry and shrimp. Often mistaken for Eleocharis acicularis, it grows taller and is better suited for larger aquariums. Suitable for both submerged and emersed conditions, it’s a flexible and attractive addition to planted tanks.
