Self-segregating Angelfish?

I have my five half-grown angelfish in an 80gal tank. There's some live as well as artificial plants, and they share it with two bnp's, three male guppies, and a young (about 8 inches long) bgk. Everyone seems to be doing fine together.
There are two electric blue marble veiltails, 2 blue glitter wide fins (I think), and one blue pinoy veiltail. In the last couple weeks, I've noticed the the two blue marbles consistently hang out together, as do the two glitter wide fins. The blue pinoy seems to just hang out in between, and is pretty much ignored by both. The two 'sets' bicker a little if they get close to each other (they do't seem to be defending territories), but nothing serious.
So is this maybe the beginning of pairing off and I just got lucky, or do angels have a preference for like-colored fish?

 

I’m hoping you got lucky and have two pairs of like angels.

My breeding plan is 10-12 juvenile angels of the same type in a 90 and let them pair naturally. Then move identified pairs into 29s for breeding. Hoping to get just 3 pair out of the 10-12 and rehome the rest and use the 90 for a rearing tank.

I think my biggest challenge will be finding the same type of angel from 3-4 different sources to minimize in breeding.

I’ve researched a lot on breeding angels and most remove the eggs. I plan on letting the parents rear them for the first 2-4 weeks. I know I will experience egg eating, fry eating but want to watch the nature of parents rearing more than making $$.

 

They have a preference for like colored fish when they are pairing up. If they are two inches in diameter (at least) then your are seeing pairing behavior and your odd angel out is likely going to come under further attack as they start spawning.

 

Well, yay?
I was hoping to get one pair -- ideally it would have included the blue pinoy (who isn't really blue, but an amazingly deep velvety black). I have a 40G cycled and ready to house one pair, and planned on the other three same-sex fish staying in the 80G for now, until my other 40G is freed up. The potential of two pairs could be problematic.
I may see another aquarium set up in my future. My husband's going to kill me.

You can force a pair if you figure out the genders of your angels, you can pair them up as you wish and cross your fingers, but most angels when offered an angel of the opposite sex are willing to pair up and spawn (however as with any pair you have to watch for signs of "divorce" which can be fatal if not separated).
