the mom is definetly an african cichlid from lake malawi. i'm not sure of the exact breed though. it looks like some of the ones i have that are believed to be mixed breeds (the possible combinations are endless really). the fish that is circled looks like a kenyi-also a malawi cichlid. the babies could have a father of any malawi cichlid in that tank, which from the pic i can see several in there. most likely, it was one of the blue ones though-my guess is your friend was circling who he thinks the dad is, and he is probably right. you will know when the babies get a lot bigger who the daddy was. i have had three generations of babies born in my african tank and each time, the babies have come out the same color as the mom-mine have all been blue too. so expect the babies to be blue....eventually....it will take a long while for their colors to show up.
