Who is the Blyxa japonica?


Who is the Blyxa japonica?

In the wild, this plant can be found in Asia (Japan, China, Vietnam).

Blyxa japonica has a reputation for being very difficult to grow in aquariums. However, in good conditions, it can measure up to about 55 centimeters (22 inch) and decorate your aquarium nicely. Moreover, this beautiful size will be proof that your plant likes your tank: it starts to grow and take volume.

Its predominantly olive-green colour can, under a good light, turn red.

Planting and maintenance

How to plant and maintain the Blyxa japonica?

The planting area does not matter to the plant. On the other hand, we rather recommend the planting it in the front or in the middle because it becomes beautiful when it is expanded and you will thus be able to enjoy it better.

The main difficulty lies in its acclimatization and its recovery after transport. Indeed, she is quite sensitive to the lack of light and Co2, which are the conditions imposed during her journey to you. After this difficult time, your plant should begin to grow and flourish in its new environment; offering you beautiful long stalks, sometimes exceeding 50 centimeters (19.5 inch)!

For the lighting, do not skimp! This plant requires intense brightness (ranging from 1 watt for 2 liters (0.5 gal) to 1 watt for 1 liter (0.2 gal) ideally).

It will necessarily need a contribution in Co2.

Not particularly suitable for a beginner aquarist.

Small tip: the plant tends to float easily and it is quite difficult to maintain it in the substrate at the start. Use a thread to hang it!

Very poorly supports parcel trips. If you still decide to buy it over the internet, you risk getting it all returned. Do not worry. It will be enough for you to plant some stems so that the plant takes again a new existence.

This plant is well suited for aquascaping, but its difficult maintenance is reserved for confirmed aquarists!
