I'm surely no expert, but I had a similar problem when trying to aquascape a 29 gallon which is 12 inches wide as well. Sticking to tall leafy plants like Cyperus helferi or Jungle Val type plants helped the tank looking fairly deep and tall. When paired with Hygrophila corymbosa "compacta", or some other swatty looking plant it worked nicely too. So the general idea is to pair tall and short plants together to form sort of a tiered effect across the whole scape.

Anyone have examples of aquascapes that can help Trena (and me) get an idea of how it would look to scape plants within such a tight space?
