Genicanthus Angel Sex Change

Currently, I have a female G. semifasciatus in my tank that's been around for almost a year and is around 4". I actually bought it when it was at the verge of fully transforming to female. I'm planning to add a 3" bellus when it becomes available here (they come in large shipments once the season comes). Would the 4" semifasciatus turn into a male? Thanks.

I bought a female semifasciatus trio a couple years ago and the largest, which was about 3 1/2", transitioned to male six months ago. This was in a large, lightly populated tank however.
