I take it this would be the 240L tank you were talking about in your other thread?
If you're planning on putting anything neon tetra sized or smaller in there, avoid angel fish. If everything will be bigger than neon's, angel fish are an option. You could also go for some of the apistogramma genus - cacatuoides or agassizi are both popular choices. Keyhole cichlids are an option, as are German Blue Rams or Bolivian Rams.
Not all together mind. Have a look at those and tell us your favourites, and someone should be able to come up with a suitable stocking list.
