Hi all, This is my first aquascape, and I'm liking the way it's turning out so far, but not completely happy with it. I just ordered some staurogyne repens to add to the foreground. I'm still not absolutely sure what plants to put in the background. I want it to look more lush and taller in the back. Any comments/criticism/suggestion? Like I said its my first aquascape, so any direction would help a great deal. Thanks so much for your time!
