Bellus angel M/F compatibility

[Delphinus]

I have a pair of bellus angels (Genicanthus bellus). Have had them around 2 years or thereabouts and got them from a Canreefer shutting his tank down.

Anyhow the aggression between the two is something that sort of makes me uncomfortable. The male is a complete jerk to the female.

After all this time, it's clear it's not something that's going to lessen as time goes on.

I guess my question is, are pairs usually like this? Or is this basically not a "pair" but just a male and a female and they hate each other?

I'm getting tempted to think about selling one or both.

The only hesitation I have is that since they are sequential hermaphrodites or whatever the term is for when fish turn from one gender to the other .. is the male simply reasserting his dominance so that the female stays female basically and thus he keeps her from turning into a rival male?
