A 220g can become amazingly small when big Central American cichlids are involved...and there's no sure thing cookie cutter for success in stocking a community of them. You'll almost always need a spare recovery tank (or a divider for your main tank) to isolate the fish that result from inevitable beat-downs.
If color and activity are your primary concern, you could go with a single, large cichlid (red devil or synspilum...now classified as melanurum...or another Paratheraps or Vieja...or maybe a big red snook - Petenia splendida) and a bunch of tin foil barbs or other decent-sized active fish.
