If I were you, I would replace the red minors with a species of similar color. Red minors can be fin nippers and angels have long, lovely fins. Of course, some people keep them together and don't have a problem, but I have found red minors to be nippy. I agree with bruins that you should up the hatchet number to 5. They will be more comfortable that way.
Yep, that is what I was trying to say. Sorry for not being clear.No, I believe angel is suggesting you get a different similar-looking tetra but not nippy, like (for example) red phantoms or bloodfins.
