I hightly recommend the fighting conchs. They do a great job on the sand bed, and are fun to watch. My non-aquarist friends always enjoy watching its "elephant trunk" probing the sand and low level rocks. It's not a fish, but it does a great job and is fun/interesting to watch - what more could you ask for?
