Well then once your angels form 1 or more pairs you should choose the 2 that seem to be dominant male & female & rehome the rest.
Are they all the same color strain? They're all the same species of angels & can breed. But color (koi, silver, zebra, etc) & fin varieties (veil or short) can be mixed in varied & unattractive ways.
If you can pick 1 pair of the same color & fin shape & want to think about raising any fry, that would be best. But it's not so easy to do! It's a lot of work.
But maybe you just want a community tank of a pair of angels, a school of corys & a school of larger bodied tetras, that can be nice too.
