I've been having that same problem with almost every post that includes pictures. It says "click the image to open in full size" in a small box and it doesn't do anything. I wish I could fix the problem.

Well, there is normally only two kinds available. Live oak and magnolia leaves. What I learned is put some live oak down on top of everything, them put some magnolia on top of the live oak. But don't put the magnolia everywhere. just put small amounts here and there, don't litter the whole tank with magnolia unlike what you should do with the live oak. I think why you should not cover everything with magnolia leaves has something to do with letting the soil breath. the live oak on the bottom helps the larger magnolia leaves to not sink down and become flat.
