I think it's going to be real tough trying to figure out what this fish has in it. The fin coloration/pattern matches no CA cichlid species. Sometimes a cross has a very obvious resemblence to one or more of it's parents , while other times a cross produces some unique traits, resembling neither parent. One can always speculate, but it's often difficult to be certain what it is a cross of, unless the fish pocessess very obvious traits that are peculiar to a particular species.
I'm not even so sure the fish contains Veija, though it seems quite possible. The horizontal line would seem to suggest it, though there are many other CA cichlids from which this trait could originate from. The way the blue sorounds the black blotches looks like a flower line and might suggest it has flowerhorn ancestory, which would mean it is a mix of MANY CA species. Those that know the various strains of flowerhorn might be able to speculate which strain most resembles your fish, though I certainly couldn't tell you. The mouth/snout , as you have noted, is definately not Veija, but rather, resembles an Amphilophus or other CA species ( from midas?, flowerhorn?, trimac?, mayan?, festae? etc.)
