The local river one is plausible, though you'd have to move the tanks to the wall to prevent people tripping on filter wires ect unlessone could find a way of running the wires under the floor or carpet. The tanks in the pic are obviously overstocked, but I think the tanks would have to be a lot bigger if you wanted to breed edible species in them.
Even so, as a tropical tank the Local river design would look very nice indeed if planted and scaped well.. I really like the glass bulbs holding plants on the tops.
