Hi bro. Im not an expert. But jus to share... Maybe u can list down e angel fish which u wanna keep. Maybe i can tell u which is to go in first. My tank is e same size as yours. Ive got bluering, majestic, asfur, blueface, regal, coralbeauty, king, blue, earspot, scribble, french, queen, africanus n rockbeauty angel. They do chase each other time to time. But not so serious...
