Hi all, I've received some stalks of blyxa japonica through post. the condition of the plant is not good as some leaves melted and its turn yellowish. its still alive though. i've dropped these temporarily into my smaller tank, as my 3 feet tank is not ready yet. i've tied it to some stones to keep these in upright position.i can see the pearling from the leaves especially the melting leaves. How do i trim these unhealthy leaves? or do i leave it until it regain its 'greenery'
