Compatability?

[bunlet]

Are rainbowfish ok with angelfish? In my 55g planted tank I have 2 clown loaches, 2 australian rainbows, 4 angelfish, 6 zebra danios, 4 otocinclus, and 2 african dwarf frogs. Someone on another board said that I have to return either the rainbows or the angelfish. Please say it ain't so
