If you want a breeding pair of any cichlids, and add a single interloper, you should expect carnage once the pair start to breed, especially in such a small tank. Any pair of medium size cichlids will see the entire tank as their territory, and try to kill any others once spawning begins. You might get away with it in a 6 ft tank, and even then, once spawning began you might need to divide the tank.
And any single species that could stand up to a united pair, would then be able to eat all the young.
Of course if that is not a conrcern, then it doesn't matter.
