Blyxa japonica is native to nutrient-rich, shallow pools, swamps, and slow-flowing rivers in East and Southeast Asia. The plant has become well known thanks to Takashi Amano and his aquarium works from the 90s. Blyxa has a characteristic grass-like appearance that moves easily in the circulating aquarium water and creates a sense of dynamism compared to other more robust plants.
Carefully remove the pot and rock wool, rinse the roots and divide the plant if needed. Plant according to its growth habit; rhizomes remain above the substrate, while stem and rosette plants are planted with their roots in it.
Does Blyxa japonica need CO₂?
Requirements vary by species. Added CO₂ and balanced plant nutrition often improve growth and colour, but match light, nutrition and CO₂ to the requirements in the product description.
Where in the aquarium should I place Blyxa japonica?
Placement depends on mature height, growth habit and light requirement. Plan so it receives enough light without shading smaller plants.
What matters after planting?
Provide stable lighting and nutrition and avoid major changes while it establishes. Some older leaves may deteriorate as the plant adapts to new conditions.
