The females are a dull brown with stripes. Yours is stressed so his coloring is off some.. This is as best as I can find, a Pseudotropheus elongatus.. Please see this copy/paste link and do the images under the pic to see different ones.. Hope his helps U..
This is a guess on his genes as the pic is not a good one of his face. This may not be the Elongatus but a different speices of Zebras.. NO the face does not change once at adult.. But U can go through the files at that link and maybe find him.. Did U get him at a LFS or a friends tank?? IF a hybrid, he would have more odd shapes then just the mouth area. could also be a deformed one from the spawn.. I have seen this in my kenyi sometimes.. hard to tell with out knowing where they came from.. IF I have time later I wil do a different search..
Hi all..just woke up. When I posted mine last week, I called it Elongatus...others suggested socolofi. I still lean toward "Elongatus ornatus". Put that into google and goto images
Incredible shot. It's like they're posing for you
