That is a peacock. I cannot see if there is red on his fins. If so I would say Auloncara Stuartgranti Cobue. If he has orange on his tail he could be Auloncara Stuartgranti Ngara Flametail or Auloncara Koningsi. His eyes are not big enough to be a Auloncara Masoni.
Here is a link to cichlid forum species profiles. It is great for this type of question.
I think I have the same fish pretty sure mine is an electric blue alhi peacock from the research I have done. I can't tell if yours has the orange in his fins mine does from what I read that was the difference between the hap and the peacock.
