Look for subtle differences in head and body shape. Maybe also differences
in the length of the black "ear" flap.

I raised a bunch of juveniles in a 20 high and they spawned while all
crowded in there with no special treatment. The fish matured at a small
size and there was clearly one dominant male who was the first to spawn. I
moved them all but the big male to a 29 and other males spawned too. I
think the extreme crowding diffused aggression and allowed spawning in a
community. There were rocks and plants for cover. I had the same scenario
in a crowded 70 with cichlids, etc. A green sunfish fanned a nest in the
front corner and spawned with a female who was in the tank. Suggest
throwing in a bunch of greens or something you don't mind losing and
letting them bear the brunt of the aggression. Got any port cichlids?
Those might work too.

I have observed the same.
