Please confirm i.d

Anyone out there able to clearly identify the Cichlid in the attached picture.
I rescued seven of these Cichlids four months ago; currently the largest are approximately 12cm in length. These larger, more dominant fishes have over the past month gradually lost their all over golden colour, being replaced by a more mottled area of grey/dark green along their upper backs. Two prominent lower front teeth are also recent additions!!
I have my suspicions but would welcome any views/comments.

I am going to go on a limb and suggest that they are Parachromis Dovii

I've got a feeling its a
Parachromis friedrichsthali or a Nandopsis dovii

Don't know the ID but just posting to say its a nice fish
