Blue speckled cichlid....??

Hey......need help people.....almost 3 years ago I picked up a 1 inch African Cichlid. as a juvy....I cant for the life of me now figure out what species he is...he's about 6 1/2 inches now......dark blue color througout his whole body.....and the thing that makes him different....silver like speckles throughout the whole body.......hes not a hybrid because I have seen this exact African in other peoples tanks....I believe hes from Lake Malawaii....not 100 percent sure though....if anyone can think of what he might be I give best answer right away.....thanks much.....
