I have a shoal of 7 angels in my 75g with some red phantom tetras, cory's and oto's. Everyone gets along fine. Angels aggression seems to go down with larger groups but a 75g limits that number. My tank has the happy number at 7. I also keep the numbers low with the others in the tank. Also with this many I needed to run more filtration so the tank runs 2 emperor 400's. Plant density also plays into how many you can keep as they need room to swim.
