my male is dark brown to blackish mix his jaw structure isnt to different just more square and deeper mouth, he looks different than your female in the picture. I have a powerhead in the aquarium and with my filter the water gets pushed around quite a bit. My powerhead is poined over a large rockpile where they like to lay at night. The female may be a bit too small to mate but maybe there just saying hey when the time is right we will . As for pics they will be up shortly when they cooperate.
