Blue Throat Trigger...male or female??

I wondering if anyone can shed any light on whether my Blue Throat trigger is male of female?



So males are identified by their obvious blue throat and yellow fin/tail markings:-

and females are identified by their lack of blue throat and yellow fin/tail:-

and this is mine....yellow tail markings but no blue throat...

Anyone any idea whether this is male or female?
