Blyxa aubertii

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Due to its potential size, it is best suited as a midground to background plant. It forms a substantial, flowing bush that looks incredibly natural among hardscape. It should be given plenty of space to spread its long leaves.

Botanical form

Rosette

It forms a large, dense rosette of long, narrow, grassy leaves. The leaves are typically a bright, fresh green, though they can show slight reddish tints under intense light. It grows into a massive, single clump.

Growth

Fast

The growth rate is moderate to fast when provided with ideal conditions. It will continuously produce new leaves from the center, increasing the density of the clump. Without adequate nutrients, its growth slows significantly.

Substrate

High

Blyxa aubertii develops an incredibly thick and deeply penetrating root structure that demands a high-quality, nutrient-rich substrate. A deep layer of active aqua soil is essential to supply the heavy macronutrients required to support its large, dramatic rosette of long leaves. If planted in plain sand or shallow gravel, the plant will fail to anchor properly and will suffer from severe nutrient deficiencies.

Column fertilization

Recommended

Supplemental liquid fertilization is beneficial, ensuring a steady supply of trace elements. However, it should not be the sole source of nutrients. Maintaining balanced macronutrients in the water helps keep the foliage clean.

Root fertilization

Recommended

A deep, nutrient-rich substrate is vital for Blyxa aubertii to reach its full potential. The frequent addition of high-quality root tabs will significantly boost its growth. It develops a very extensive root system.

Trimming

Occasional

Maintenance involves carefully removing older, outer leaves that have become damaged. Cut the leaves off as close to the base as possible. Do not cut the leaves across the middle.

Propagation

Division

Propagation is achieved by separating the small basal shoots that occasionally form. This can be a slow process, as it does not throw out long runners. Gently tease the plantlets apart.

Sensitivity

Moderate

It is relatively hardy once established but can be prone to melting if uprooted. It prefers stable water parameters and may suffer if CO2 levels fluctuate wildly. Its fine leaves can be a magnet for thread algae.

Layout role

Midground, Background

It serves as a fantastic structural plant, creating large, grassy focal points. Its flowing leaves add a sense of movement and natural grace to the aquascape. It contrasts exceptionally well with broad-leaved plants.
