I find Angels far too tempremental to bother with.
Dwarf Cichlids are always a good choice, But apistos and Cockatoo's can be very aggresive, i would tend to steer clear from those. Kribs and Rams are really neat fish and aslong as you have plenty of females to males your fine.
Keyholes are awesome cichlids and are very gentle, would be an awesome addition to your tank (if your interested i will be aquiring a few from down south soon, as i have found them very hard to source here in wellington)
Do not get Firemouths, they get big and will eat small fish and are ugly regarless of there colouration.
