IME I have found the females stamp their fry more so than the males yet a lot look for top notch males and skimp on the female.
This has been my experience too. That is why, even with heavy branched males.. you still get an 8 ray girl. Ideally she has good length too.. to help balance out those extra rays. In F1 look for length of that tail again and pick the best balanced females to use for breeding. Breed for balanced girls and you will have great males. Males are just females with longer fins.
You go from this.. looks like a nice female form wise..
to this... male is in spawn tank so sorry about the pphoto. He took 1st in his class at convention so is a pretty decent male.
Even as bad as this picture is.. you can still see the balance in this male. I bred for great females first. And this line was over branched and way out of balance 4 years ago. This is the line I have worked the longest.
