Dan, My tank has a 4' by 2' bottom area with lots of Mopani wood and a lot of plants. I wouldn't try to breed apistos with clowns or just about anything besides otos in a 29gallon. Even with a 4' by 18" tank area, my cacatoides were unable to escape predation by a dozen pygmy corys! And that tank is chockful of Anubias plus wood and slate pieces.
