Do you mean you want to make it look like this?
Personally I think it is easier to start out with Java fern, anubias, and Amazon swords. That is what I wish I had done and what I will do if my plants don't stop melting. Java fern come in different shapes. Here is the only pictures of Java v needle leaf I have found. The leaves can get taller as Hygro Willow.
