Help with sexing harlequin shrimp

[capnjazz]

Can anyone help sexing these harlequin shrimp? I assume they are both female (due to the blue spots underneath) and that is why they are fighting but it's hard to get a clear shot.

Males apparently lack blue pleopod tips.

Yeah, I think they are both female but I figured I'd ask here before I went back to the LFS to exchange one for a male. From the picture, do they look female to you?
