Today, just as 3 years ago when this topic was created, if it is small enough to fit in an angel's mouth it risks being eaten.
I don't care if you keep the angels separate, or together, with other fish, or keep the angel as an adult for years by itself, they are cichlids, and will eat live food if given the chance. Individual angels have individual temperament, some more aggressive than others. Aggression & eating are two different issues.
An adult angel can easily eat an adult neon, adult male guppys are not a whole lot bigger. An adult angel can open its mouth much larger than you would think.
