Lyretail anthias changing sex

[Hammer100]

I initially added 6 lyretail females about a year ago. One changed over to male after couple months.
Now two more look like they are changing over as well. Should I be concerned?

Most def. Is there any aggression yet?

Nothing really bad yet. But I have seen the 2 that are changing or appear to be changing swipe at the others like the male

I've seen multiple male lyretails in several larger tanks with no problems. Not sure where the cutoff might be though. The tanks were over 180g. Under that and I'm not sure if it would work.

In most cases the groups numbers will start to diminish due to males fighting and competing.

my tank is 180 so hopefully they work it out.
