Can't figure out the sex of my GBR

[drbabigrll]

Hey guys! I'm new to this but here goes my question? I need a little help figuring out the sex of my rams. I was told my small German Blue Ram was a female when I purchased her. But I'm not convinced. "She" seems pretty feisty towards my other ram who is supposed to be a male. I would love to breed these guys in the near future

Here is a picture of the one that was supposed to be a girl. Any help would be greatly appreciated!

For some reason only one photo uploaded so here's a video

I'm going to say that that looks like a female. The top back fin looks rounded.
Look at these pictures:

That's what I thought but then the black spot doesn't really have blue specks in it. Make me think maybe it's a boy... Thoughts?

Here's another picture

Still looks like a female to me. In the first picture you posted, you can see faint blue dots in the black patch.

Looks female to me.

Any idea why the female would be picking on the male? She tends to come at him and he backs away from her. His black stripes are only really visible when she's next to him and after she tries to scare him off.
