Yes, that's correct ... they aren't ... although they flee from aggressive behavior on the part of the dominant fish.
But none of them have actually retreated to a spot or spots and stay there ... they'll all still cruise around the tank to some extent ... and more so now, as opposed to when there was less structure.
It's looks like I had the terminology wrong - should have been: (danios as) target fish ?

That's appears to me to be the case ... although there is an additional development.
Three of the five are roughly the same size, with one of these tending to be the dominant one, who has tried to rule the tank.
Next is a somewhat smaller one - maybe roughly half the size of the first three above - which was the one I picked up today. He's still holding fins erect in interactions - which seems to cause aggressive behavior on the part of the dominant fish.
Finally, there is one about half the size of the one immediately above. This one has learned better than to display erect finnage.
And when I say "half the size" above I mean body mass not length. Just guessing, I'd say they might be from three successive spawnings.
The additional development is that the one who was accepted into the dominant one's area/side of the tank seems also to be spending time with the other larger one.
But the majority of the shimmying and shaking is with the dominant fish.

Not a lot of demand for "unknown peacock female".
Got it, makes sense.

Yeah, sorry ... I didn't make it clear - there is only one group of peacocks: 5x of A stuartgranti Ngara
