Blyxa japonica

Blyxa japonica has not been used in aquariums for long, so little experience has been gained with it so far. In general it is difficult, and probably demands both soft water and CO2 addition to thrive. But it is highly decorative, and unlike B. aubertii it forms not a rosette but a beautiful stem which is densely covered with dark-green leaves. It should be planted in groups to achieve the most decorative effect.
