If your guy has the black vertical line going through the eyes and I see the black dot with blue spangles I would say almost positively that you have a
GBR there.
They are South American Cichlids and should not be in the tank with your Africans.
They are great fish to keep and I had them for a long time, now Ive been keeping Bolivians and am down to one. (I have a hard time finding GBRs and Bolivians where I live.) The GBR can be sensitive to keep, they tend to be bottom dwellers and like to hide in the grasses and plants.
I really like these little guys.. and they are very personable once they get used to you.
But Im afraid you may have to find another home for him because of those Africans you have in the tank.
