I have noticed that one hybrid is missing from the list thus far into the thread. The Angolan x Ball. I realize this is not as much of a stretch for the simple fact that their natural ranges do cross, but it is still a hybrid. It's been awhile since I have seen one, but they were done a number of years ago. This hybrid I find the most unsettling, as the captive population of Angolans is still not that great, and I don't know why you would want to "muddy" the Angolans at htis stage of their population.

Just my .02 cents.
