On the topic of hybrids:
I don't like hybrids between species that are as similar in looks as BPs and Angolans. It wouldn't have been hard to pass of a F1 angry ball as a new BP morph, or angolan morph for that matter.
I much prefer hybrid projects where the offspring have a distinct look all their own, such as the woma x ball, burm x ball, and carpet x gtp.
