Make sure you plant the back corners pretty heavily so that the Bushfish will have a skulking area if the Angels get feisty.
Now, you will probably see some aggression in the bushfish. I have 3 in a tank that's way too small at the moment (moving them soon - just made a deal for a 90 that will be easier to set up than the 110 I'm currently dithering about) and they beat the snot out of each other for about a two weeks until they had their pecking order straight. Had some visible wounds, little bit of fungus, treated with Melafix and pimafix and it cleared up. Haven't had any damaging aggression in the last 3 months or so. I don't think they'll go after the angles, though. They didn't go after the gourami that was sharing the tank with them at the time (She's been moved to be the Queen of a 40 gallon).
