This may have been answered already, but clowns and chromis will do fine. I had 2 clowns and 4 chromis, and they all lived happily together. Just make sure not to overcrowd them, as crowding can make almost any fish unhappy.
Nice photos! My dream is to have a wall tank one day.
Hopefully in the next year or so I can.
