As a species (not Breed) it looks like Amphilophus Citrinellas the MIDAS Cichlid - which has the rounder blunter mouth. However if you haven't been told what species it is it could well be a "Midevil"
Might be a female... they have spangles at an earlier age which later fade... the early tell tail signs are a dark area in the dorsal fin the the bars aren't showing...
Below the same fish younger and then getting sexual mature
