Blyxa Aubertii (Bamboo Plant or Roundfruit Blyxa)

Blyxa aubertii, commonly known as the bamboo plant or roundfruit Blyxa, is a striking, strictly submerged aquatic plant highly favored in the aquascaping community. Unlike its smaller and more common relative, Blyxa japonica, Blyxa aubertii forms a much taller, dense basal rosette of long, grass-like leaves that gracefully sway in the water current. Under optimal conditions, its coloration transitions from a translucent green to a dramatic bronze or reddish-brown hue.

Quick Facts 

Origin: Widespread across tropical and subtropical Asia, Africa, and Australia

Max Size: 30 to 50 cm in height

Placement: Midground in large tanks; background in medium tanks

Growth Rate: Moderate

Difficulty: Moderate to advanced

Aquarium Care & Requirements

Lighting: Medium to high. Moderate lighting keeps the leaves a vibrant green, while intense light brings out stunning red and bronze pigmentations.

CO2 Supplementation: Highly recommended. While it can survive without it, CO2 injection ensures stable longevity, lush growth, and prevents the leaves from becoming overly brittle.

Substrate & Nutrition: It is a heavy root feeder. A nutrient-rich soil substrate or regular supplementation with root tabs is critical for its health. Fine gravel or aquasoil works best.

Water Parameters:Temperature: 22–28°C (72–82°F)

pH: 6.0–7.0 (prefers slightly acidic, soft water)

Hardness: 5–6° dGH

Propagation and Handling

Handling Caution: The leaves are exceptionally fragile and can snap easily during maintenance. It also does not tolerate aggressive or boisterous fish that might pick at or uproot it.

Propagation: It reproduces vegetatively by developing side shoots and splitting at the base. You can propagate the plant by gently pulling these individual shoots apart at the root base and replanting them.

Flowering: In a healthy tank, it frequently sends up thin stalks that produce small, white, self-pollinating flowers just below or at the water surface.
