Please help sexing (Senegal Bichirs)

[Mr. Mom]

Hoping I could get some assistance here on sexing these 2. I know the male's fin is supposed to be larger ... but maybe its wishful thinking ... I think I've a male and female.
I believe this could be a male


I believe this one might be female


The two of them saying hi ... possible female on left possible male on right


So am I having wishful thinking or do I have a male and female? All help is greatly appreciated ... Thanks in advance

 

[Dr.B]

Yep male and female

 

[Burbotman]

First one def male, might have pair

 

[Mr. Mom]

Thanks you guys ... its what I was thinking but I've never tried to truly figure it out before.

I chased these two off and on all day ... trying to get these pics. Anytime the camera came in view they swam away ... Frustrating.
