Good tip - I'm definitely working out the appropriate aquascape. Right now I'm toying with the idea leaving the entire foreground open with just a scattering of larger river rocks, and adding a small power-head to simulate stream flow. Then dense planting and driftwood in the background as the stream bank. But I also thought mabe a low groundcover in the foreground along with the river rocks would look pretty sweet as well - something that wouldn't mind the water flow from the powerhead.
