I think U misunderstand me Dolnald. at the start, I have no mean to advertise that all the plants using in my tank come from VN. many of them come from other coutries. I just use them to try to imitate a sight of Vn jungle. that just like a painter use some aquarelles made in other coutries to paint his country's landscape painting. if what U say is right, I don't know how many one is to be criticized.
