Looks like an insignus (P. spilonotus Tanzania) to me. Has the same beak nose, blue coloration on the face and broken melanin along the mid-line. My breeding group have a bit more of a broken line (more like 3 wide spots), but it's close enough.
I have 3 just like yours. They were given to me. I was told they were insignus also. Mine are all females. They tend to hang at the top of the tank. Anyone no why this is?
