20 years ago I could walk into a LFS and be reasonably sure what was marked, was what it was said to be.
I don't believe that anyone can know if any Vieja (or just about any cichlid) is what it is called these days.
Sad but true, there is no way seeing a photo, or even live, that anyone can tell what any Vieja is just by looking. In any spawn, a certain percentage, look like the mother, and equally so, the father. But either would be a hybrid in a crossing, so you can give a name like king-sumo this, or kokface that, in the end, a mutt is still a mutt.
