Thanks for the input.
mrbman--I agree that the rear right should be the high point, the rear left, and right front should be medium, and the left front should be low.
Blyxa is an awesome plant, but I already use it heavily in a couple of other tanks, so I want to pick something different.
Anubias has already made it into the cracks in the rocks ( and I really like it there). I played with it some last night before I went to bed. If I title it "tossed salad" it might be ok, but so far, it looks like just that.
