ive had a female swallowtail angelfish for 7 months and also a coral beauty for 9 months no aggression has been shown between these fish if i were to add a male zebra swallowtail angelfish would this cause any aggression in this group? tanks 150g 6 foot long

Possibly. Depending on the size difference between the male and female, I have seen established females bully newly introduced males, sometimes to the point of the male transitioning back to female, sometimes to death.

You would be better off adding a smaller female swallowtail, using an acclimation box.

Agreed. IME this is the much easier way to go about it.
