Sexing Dwarfs Please Help...

[Harlequins]

I've had these dwarfs for around 6 weeks,and the one i thought was a female appear to be colouring up,it was a silvery colour,now has red & blue stripes appearing,and unsure whether its me,but seems to have a pointed dorsal fin,so now i'm not certain of the sex.

I'm now wondering if this is a young male instead,i've attached pics for help to decide please.Thanks

This is the male


Now here's pics of what i think is the female???
