How does one know that a lot of the Cichlids we call Pure blood line (or whatever the term may be) arent hybrids themselves? I mean plenty of peacocks, haps, etc... will mate with different species of peacocks or haps. i.e. Say the man who discovered the Aulonocara jacobfreibergi just assumed it was a "pure" fish yet years before it was ever discovered it was unknown that it was actually a hybrid derived from two different Aulonocara? Because I know they tend to cross-hybridize. I guess God or Darwin is not on the MFK forums so I understand I might be looking too deep for an answer that is unanswerable. Just wondering if someone could set me straight on this theory of mine as if im not understanding things correctly or if it is in fact still a mystery of many Cichlid hobbyist??
