Yeah. I do love the fish's colors and form but topline is something I always observe. Even in fry. I don't breed fish with a bumpy topline without being ready to cull hard. Remember even of you have fish with nice topline there are still gonna be those few who have supe bumpy ones. Imagine breeding one with a bumpy topline.
actually if you look closer with your trained eye you will see that its rounded and because of his markings or coloration is making it look bumpy and im sure the original breeder of this particular fish breed out the imperfections a while back.
