Not to toot my own horn, but TOOT TOOT!
I have a thread in this forum with a photo of my pair of Pelmatochromis nigrofasciatus sitting on eggs. I looked at the photos you had in the other thread, I only saw a male , or males. Females tend to be much smaller and stockier in appearance. Very mild mannered species, my 12cm male doesn't even chase the 3cm swordtail fry in there.
If you can't Dazzle them with your Brilliance, then try to Baffle them with your BullS***!
