I think this is what i have in my fish tank

Pseudotropheus Zebra / Metriaclima Zebra

After much searching and looking at fish that look almost the same, I think it's this. I'll post some actual pics of my fish in my tank but till then, this will have to do for now. The search to enlighten myself continues. Funny thing is, even scientists cannot agree on the name for the fish.
Due to a technicality with scientific naming conventions, there is still some debate as to whether Maylandia or Metriaclima is the valid name for this genus, though most sources seem to indicate Maylandia will become the accepted name.

Quote of the day : Since you know, you get to choose a name when you are pope. If I ever became pope I would choose the name Pourri. So people would call me Pope Pourri, and they would be forced to laugh whenever saying my name.
