To each his own, and i agree with the comments that dogs are all designer hybrids and who knows what rays mix in the wild.
As far as wild Hybrids, I 100 percent agree this happens more than people acknowledge... especially in the motoro complex (aparicio, mot,mm etc) rays cross breed easily in captivity even when presented with the same species (unlike most other fish) and i have never heard of infertility resulting from a cross (like a mule or flowerhorn). I think we try to divide them by distrubution and local promintent markings when they are essential just that localities.
I wish someone would start a thread of hybrids, but only known gene lines to help ID rays that pop up with questionable backgrounds.
