Mystery African Cichlid

Hard to tell from the photo resolution, but a pseudotropheus of some type. Either a hybrid or pseudotropheus socolofi displaying prominent stress barring (in the latter it's a temporary display, in the former it might be a permament pattern).
 
possibly very pale/stressed pseudotropheus acei, although I would expect darker, broader stress lines,

...I don't think its a socolofi because of the purple tinge, would expect a blue shade.

or a pseudotropheus hybrid
