wanting to create a cichlid community

[snowyangel]

So far I'm leaning towards kribs, blue or bolivian rams, keyholes, brichardi, Apisto or Severums. I would like to have atleast 2 species of these kinds(or another kind if you know of one) together in this tank. The water is like so:
ph: 7.3
hardness: 120 ppm
nitrate: 10 ppm
........and ammonia and nitrite are obviously at zero. Only thing in it is a golden striped pleco and some pygmy cories.
So what kinds of cichlids would be fit for this water type and with each other in the 55g? How many of each kind?
Thanks in advance

You can get away with 1 Sev and maybe 2 keyholes, and a couple of catfish.

keyholes sound like a good choice snowy

Anything else, like the rams or kribs? I want something with colour, and keyholes are pretty just not too colourful(but i'll still get them ).
