I have a few male guppies in with my angels. Along with some neons, they aren't too aggressive, because I keep them all in my 200 gallon tank

my 29 gallon is filled with 2 male guppies, 1 black skirt tetra, 2 australian rainbows, 1 large pleco, 3 male gouramis, 1 female gouramis, 2 red eyed tetras, and about 5-6 angels.
The reason why I have neons and angels together in my 200 gallon tank, is because my tank is huge, and is well planted. So there is a lot of space between the angels and neons. I have about 100 neons, and about 12 angels, altum angels too. So I can put in as many angels as I possibly can.
Also, my 350 gallon has angels and discus fishes together along with some new buddies.
