I know what you say about neons being natural food to the angels,but my neons get along just fine with my angelfish.I must say my angels grew up alongside neons,so they are very used to them.I also have some ramis and all three diferent types of fish will feed next to each other.You should see how crazy they get when is lunch time.
I have seen the angels attack one another,but never a rami or a neon,.Little fishies a lot smallers than the escalares never fear them.Could it be 'cause there is plenty of room to swim away?Donno.But I will support the thought of not having neons and angels together.
