Once you get all the water issues solved, good starter African cichlids are: Red Fin borleyi,
Yellow fin Acei, Hongi, Yellow lab, Williamsi blue lips, one or two Peacock cichlids. I've kept all of these fish. They won't get too big for your 65 gal
. And they aren't too aggressive. Try to select all male fish. It makes things easier. With Africans, lots of rocks and caves.
With New World cichlids, nothing big. Maybe Fire mouth, Bolivian rams, other dwarf cichlids. You will probably like to add schools of Tetras. With a little experience and a lot of research you can even mix certain cichlids from different bio types. Keep AA updated.
